Description

Technical Field

[0002] As people's quality of life improves, the development and research of products with medical and health functions has become a hot topic in the current pharmaceutical, health care and cosmetics industries. Ginkgo leaf extract and its preparations are representative products among them.

[0003] The extraction steps of ginkgo leaf extract generally include: raw material preparation → sterilization → crushing → alcohol extraction / water extraction → column chromatography. In the prior art, the crushing of ginkgo leaves is generally achieved by a crusher. After the ginkgo leaves are crushed, ginkgo leaf powder is obtained. The ginkgo leaf powder is mixed with an extraction solvent, and the effective ingredients in the ginkgo leaf powder are extracted through the interaction of the extraction solvent and the effective ingredients in the ginkgo leaf powder.

[0004] The existing ginkgo leaf crushing equipment has poor crushing effect and poor wall breaking effect. The effective ingredients in the ginkgo leaf powder are more difficult to be penetrated and dissolved by the extraction solvent, which affects the extraction efficiency of the ginkgo leaf.

DETAILED DESCRIPTION

[0041] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0042] like Figure 1 to Figure 12 As shown, a ginkgo leaf extract extraction device in one embodiment of the present invention includes a second shell 2, a feed port 201 for feeding into the second shell 2 is fixedly connected to the second shell 2, a sealing cover 202 for sealing the entrance of the feed port 201 is rotatably connected to the feed port 201, and the sealing cover 202 can form a closed environment with the second shell 2. A crushing assembly 3 is installed on the second shell 2, and the crushing assembly 3 can crush the ginkgo leaves in the second shell 2.

[0043] Specifically, Figures 1 to 12 As shown, the crushing assembly 3 includes a first motor 301, which is mounted on the upper end of the second housing 2. A first transmission rod 302 is provided through the second housing 2, and the first transmission rod 302 is rotatably connected to the second housing 2. The first motor 301 can drive the first transmission rod 302 to rotate at a high speed in the second housing 2. A plurality of crushing blades 303 are fixedly connected to the first transmission rod 302, and the crushing blades 303 rotate at a high speed with the first transmission rod 302. The crushing blades 303 contact the ginkgo leaves during the high-speed rotation, thereby crushing the ginkgo leaves.

[0044] like Figures 1 to 12 As shown, a plurality of first wall-breaking components 14 are fixedly connected to the outer wall of the second shell 2, and the first wall-breaking components 14 are communicated with the second shell 2. When the second shell 2 and the crushing component 3 cooperate to crush the ginkgo leaves to a certain extent, the centrifugal force generated by the high-speed rotation of the crushing component 3 causes the ginkgo leaves to move to the end away from the crushing component 3 and enter the first wall-breaking component 14. The first wall-breaking component 14 can further crush the ginkgo leaves, improve the crushing effect of the ginkgo leaves, and improve the wall-breaking effect, so that the extraction solvent can more easily penetrate and dissolve the ginkgo leaves after the wall-breaking treatment, which is beneficial to the interaction between the extraction solvent and the effective ingredients in the ginkgo leaf powder, and is beneficial to improving the extraction efficiency of the ginkgo leaf extract.

[0045] Specifically, Figures 1 to 9As shown, the first wall-breaking assembly 14 includes a plurality of first wall-breaking shells 1403, and the plurality of first wall-breaking shells 1403 are sequentially arranged from top to bottom. A second transmission rod 1402 is provided through the plurality of first wall-breaking shells 1403, and a second motor 1401 is installed on the upper end of the second transmission rod 1402. A first wall-breaking blade 1405 matching the first wall-breaking shell 1403 is fixedly connected to the second transmission rod 1402. The second motor 1401 can drive the second transmission rod 1402 to rotate at a high speed, and the first wall-breaking blade 1405 rotates at a high speed with the second transmission rod 1402. During the high-speed rotation process, the first wall-breaking blade 1405 can realize the wall-breaking process of the ginkgo leaf.

[0046] like Figures 1 to 9 As shown, a connecting rod 17 is installed between the first wall breaking shell 1403 and the second shell 2, and a connecting component is installed between the first wall breaking shell 1403 and the second shell 2. The connecting component is used to connect the second shell 2 and the first wall breaking component 14, and can realize the control of the passage between the second shell 2 and the first wall breaking component 14.

[0047] like Figures 1 to 9 As shown, the connecting component includes a third through hole 1701 formed on the connecting rod 17, and the third through hole 1701 sequentially penetrates the first wall-breaking shell 1403 and the second shell 2, so that the first wall-breaking shell 1403 and the second shell 2 are connected. In the process of crushing the ginkgo leaves, the crushing component 3 generates centrifugal force, which forces the ginkgo leaf powder to enter the third through hole 1701. The thrust generated by the centrifugal force enables the ginkgo leaf powder in the third through hole 1701 to be injected into the first wall-breaking shell 1403. The ginkgo leaf powder injected into the first wall-breaking shell 1403 first contacts the first wall-breaking blade 1405. In the process of colliding with the first wall-breaking blade 1405, part of the ginkgo leaf powder will be broken for the second time, which is more conducive to the first wall-breaking blade 1405 to perform wall-breaking processing. If the first wall-breaking blade 1405 collides with the ginkgo leaf powder during the rotation, it will also cause the ginkgo leaf powder to rebound in the first wall-breaking shell 1403, causing the ginkgo leaf powder to collide at high speed multiple times. The ginkgo leaf powder is crushed twice in the process of multiple rebounds and collisions, and then the first wall-breaking blade 1405 realizes the third crushing, thereby improving the crushing effect of the ginkgo leaf powder.

[0048] The connecting rod 17 is provided with a first valve (not shown in the figure) matching the third through hole 1701. When the ginkgo leaves in the second shell 2 are crushed for a certain period of time or to a certain extent, the first valve can be opened to connect the connecting rod 17 to the first wall-breaking shell 1403 and the second shell 2. When the first valve is opened, the ginkgo leaf powder can be injected into the first wall-breaking shell 1403 through the connecting rod 17 and contact the first wall-breaking blade 1405.

[0049] It is worth noting that connecting the second shell 2 and the first wall-breaking component 14 through the third through hole 1701 is only one embodiment of the present invention, and is not the most preferred solution. The second shell 2 and the first wall-breaking component 14 can also be connected in other ways and force the ginkgo leaf powder to be injected into the first wall-breaking component 14.

[0050] like Figure 6-7 As shown, a third connecting pipe 1404 is installed between adjacent first broken wall shells 1403, the third connecting pipe 1404 connects the two first broken wall shells 1403, and the second transmission rod 1402 runs through the third connecting pipe 1404. The bottom wall of the first broken wall shell 1403 is fixedly connected with a sealing bearing 15, and the sealing bearing 15 can prevent the ginkgo leaf powder in the upper first broken wall shell 1403 from entering the lower first broken wall shell 1403 along the second transmission rod 1402. A delivery pipe 16 is installed between adjacent first broken wall shells 1403, and a second valve (not shown in the figure) is installed on the delivery pipe 16, and the passage between the adjacent first broken wall shells 1403 is controlled by the second valve.

[0051] like Figure 1 to Figure 6 As shown, a third material output pipe 21 is installed outside the second shell 2, a second material output pipe 20 is installed between the first wall-breaking component 14 and the third material output pipe 21, a fourth material output pipe 22 is installed on the third material output pipe 21, and a steam extraction device 23 is installed at the other end of the fourth material output pipe 22. The ginkgo leaf powder that has been wall-broken in the first wall-breaking component 14 can enter the steam extraction device 23 through the second material output pipe 20, the third material output pipe 21, and the fourth material output pipe 22 in sequence for steam extraction.

[0052] In the process of crushing the ginkgo leaves, the ginkgo leaf powder is injected into the first wall-breaking component 14 only by the centrifugal force generated by the crushing component 3. The injection speed of the ginkgo leaf powder may not be ideal, thereby affecting the efficiency of the ginkgo leaf crushing and the extraction efficiency of the ginkgo leaf extract. Figures 1 to 12As shown, the first transmission rod 302 has a first cavity 3021, and a rotating connection assembly 5 matching the first cavity 3021 is installed on the first transmission rod 302, and a first connecting pipe 6 is installed on the rotating connection assembly 5, through which gas can be transported into the first cavity 3021, and a plurality of first nozzles 304 for spraying gas are installed on the first cavity 3021. The gas enters the first cavity 3021 through the first connecting pipe 6, and then sprayed out by the first nozzle 304. The first connecting pipe 6 continuously increases the pressure in the first cavity 3021, so that the first nozzle 304 can eject the gas in the first cavity 3021 at a high speed, and the ejected gas forms one of the means for crushing the ginkgo leaf. At the same time, the second shell 2 can be pressurized, so that the second shell 2 is in a high pressure state, and the gas can be continuously transported into the second shell 2. When the ginkgo leaves in the second shell 2 are crushed to a certain extent, the first valve is opened, and the high-pressure environment in the second shell 2 forces the ginkgo leaf powder that meets the process conditions to enter the third through hole 1701, and accelerates the speed of the ginkgo leaf powder passing through the third through hole 1701, so that the ginkgo leaf powder hits the first wall-breaking blade 1405 at a faster speed and forms a rebound in the first wall-breaking shell 1403, which is more conducive to the wall-breaking processing of the ginkgo leaf powder.

[0053] like Fig.11 As shown, the rotating connection assembly 5 includes an inner annular shell 501, and the inner annular shell 501 and the crushing assembly 3 are integrally formed or welded, and a plurality of first through holes 3022 are provided on the first transmission rod 302, and the first through holes 3022 are located in the inner annular shell 501, and the outer annular shell 502 is rotatably connected to the outer portion of the inner annular shell 501, and an exchange chamber is formed between the outer annular shell 502 and the inner annular shell 501. A plurality of second through holes 5011 are provided on the inner annular shell 501, and the first connecting pipe 6 transports gas to the exchange chamber, and the gas then enters the first cavity 3021 from the exchange chamber. Even if the position of the first connecting pipe 6 does not change during the rotation of the first transmission rod 302, gas can still be transported into the first cavity 3021.

[0054] like Figure 1 to Figure 6 As shown, a filter screen cartridge 19 matching the connecting rod 17 is installed inside the second housing 2, and the aperture of the filter screen cartridge 19 is not larger than the aperture of the third through hole 1701, which largely avoids the situation where powder with larger particles enters the third through hole 1701 and causes the third through hole 1701 to be blocked. That is, the aperture of the filter screen cartridge 19 is not larger than the aperture of the channel of the connecting component, which avoids the situation where the connecting component is blocked.

[0055] like Figures 1 to 11As shown, there are two rotating connection components 5, and two groups of first through holes 3022 matching the rotating connection components 5 are respectively provided on the first transmission rod 302. A second connecting pipe 7 is installed on the other rotating connection component 5, and the other end of the second connecting pipe 7 is connected to an extraction solvent source. That is, the extraction solvent can be transported into the first cavity 3021 through the second connecting pipe 7, and the extraction solvent is then sprayed out through the first nozzle 304. Through the cooperation with the first connecting pipe 6, the gas and liquid can be ejected at high speed together, so that the extraction solvent can also break the ginkgo leaves during the ejection process, and the ginkgo leaves and the extraction solvent are preliminarily mixed in the second shell 2 to achieve the pre-extraction of the ginkgo leaves.

[0056] In actual use, the ginkgo leaf extraction device has a variety of setting modes, including a mixing mode and a crushing mode. In the mixing mode, when the ginkgo leaf is crushed to a certain degree in the second shell 2, the first connecting pipe 6 and the second connecting pipe 7 simultaneously input gas and extraction solvent into the first cavity 3021. Or the first connecting pipe 6 first delivers part of the gas to the first cavity 3021, and the gas is used to achieve secondary crushing of the ginkgo leaf, and then the first connecting pipe 6 and the second connecting pipe 7 cooperate to deliver the gas and liquid to the first cavity 3021. The extraction solvent and gas are ejected from the first nozzle 304 at a high speed, and the ginkgo leaf powder is mixed with the extraction solvent while the ginkgo leaf powder is crushed for the second time, and the extraction solvent and the ginkgo leaf powder are stirred by the crushing component 3, which is conducive to continuing the subsequent extraction steps. After the extraction solvent is sprayed out in a certain proportion, the first valve is opened again, and the first connecting pipe 6 continues to input gas into the first cavity 3021 for pressurization. The mixed liquid of ginkgo leaf powder and extraction solvent is injected into the first wall-breaking shell 1403 through the third through hole 1701, and the wall breaking process is completed in the first wall-breaking component 14.

[0057] Ginkgo leaf powder can be mixed with the extraction solvent to form a mixed liquid, and the extraction solvent can take away the heat generated by the crushing component 3 during the crushing process, thereby heating the extraction solvent and cooling the crushing component 3. In the subsequent extraction steps, the energy consumed for heating the mixed liquid can be reduced, which is beneficial to energy saving and environmental protection.

[0058] However, during the heat exchange between the mixed liquid and the crushing component 3, the mixed liquid is in a pre-extraction state, and the phenolic hydroxyl flavonoids in the ginkgo leaf powder will be precipitated. When exposed to the air, the oxidation of the phenolic hydroxyl flavonoids and the oxidation products in the extract are potentially harmful to the human body. For example, they react with free radicals to generate resonance-stable semiquinone free radicals. These semiquinone free radicals are further oxidized to generate quinones. Quinone substances are widely used in dyes as chemical intermediates, polymerization inhibitors, oxidants, etc. Short-term exposure to an environment with high quinone content will have a strong irritating effect on human eyes and skin, leading to diseases such as conjunctival and corneal discoloration and respiratory tract infections, and long-term inhalation will cause visual disorders. Long-term skin contact will cause dermatitis, skin discoloration and erythema, and in severe cases, skin ulcers. That is, the phenolic hydroxyl flavonoids precipitated during the heat exchange between the mixed liquid and the crushing component 3 will produce quinone substances after contacting with oxygen, which will affect human health. In order to solve the above problems, Figure 1 As shown, a gas delivery component 11 is provided on one side of the second shell 2, and the gas delivery component 11 can circulate the gas in the second shell 2. Even if the gas in the second shell 2 produces quinone substances, the high-pressure gas in the second shell 2 is circulated by the gas delivery component 11, so that the gas in the second shell 2 will not leak, and the high-pressure state in the second shell 2 is maintained within a certain range. By circulating the gas in the second shell 2, not only can the leakage of the gas containing quinone substances be ensured, but also the heat loss in the second shell 2 can be reduced, which is beneficial to energy saving and environmental protection.

[0059] Specifically, Figure 1 to Figure 4 As shown, the gas delivery assembly 11 includes a second pump 1101, a first gas output pipe 1102 and a second gas output pipe 1103 are installed on the second pump 1101, and the other end of the first gas output pipe 1102 is connected to the second shell 2. A gas storage tank 12 is installed at the other end of the second gas output pipe 1103, and a gas input pipe 13 is installed between the gas storage tank 12 and the first connecting pipe 6. That is, the gas in the second shell 2 passes through the second pump 1101, the first gas output pipe 1102, the second gas output pipe 1103, the gas storage tank 12, and the gas input pipe 13 in sequence, and is finally delivered to the first connecting pipe 6, and then the first connecting pipe 6 delivers the gas back to the second shell 2.

[0060] like Figure 1As shown, a third gas output pipe 1104 is installed on the second gas output pipe 1103, and the passage between the second gas output pipe 1103 and the third gas output pipe 1104 is controlled by a third valve (not shown in the figure). As the use time of the extraction device increases, the content of quinone substances in the gas circulated by the gas delivery component 11 will increase until the oxygen in the air is consumed during the gas circulation process of the gas delivery component 11. At this time, there are more quinone substances in the gas circulated by the gas delivery component 11. At this time, the gas circulated by the gas delivery component 11 can be discharged from the third gas output pipe 1104, and the other end of the third gas output pipe 1104 can be a waste gas treatment device, which treats the waste gas and then discharges it to avoid direct discharge of the waste gas to affect human health. Of course, the other end of the third gas output pipe 1104 can also be a device for extracting quinone substances, which can realize the extraction of quinone substances.

[0061] like Figure 1 As shown, the gas storage tank 12 can temporarily store gas. When the ginkgo leaves in the second shell 2 are completely crushed and enter the steam extraction device 23 for hot steam extraction, the sealing cover 202 needs to be opened to add ginkgo leaves to the second shell 2. The gas storage tank 12 completely stores the gas circulated by the gas delivery component 11 to avoid the waste gas affecting human health. The gas has a certain amount of heat, which can be used to heat the extraction solvent during the next use.

[0062] Preferably, in order to prevent the ginkgo leaves from producing quinones during the use of the present extraction device, during the use of the device, one end of the first connecting tube 6 can be connected to a nitrogen source, and after the ginkgo leaves are added, the sealing cover 202 is closed, and the second shell 2 is made vacuum through the gas delivery component 11. During the process of crushing the ginkgo leaves in the second shell 2 by the crushing component 3, nitrogen is introduced, and the gas delivery component 11 circulates nitrogen, and the nitrogen forms a high pressure in the second shell 2, so that the ginkgo powder can be injected into the first wall-breaking component 14, and cooperates with the second connecting tube 7 to inject the extraction solvent into the second shell 2.

[0063] Of course, it is also possible to completely evacuate the second shell 2. There is no need to circulate gas into the second shell 2 or keep the interior of the second shell 2 in a high-pressure state. It only reduces the speed of injecting ginkgo leaf powder into the first wall-breaking component 14, sacrificing some crushing efficiency and reducing some energy consumption. It can be set according to process requirements.

[0064] In order to further reduce the heat generated by the second shell 2, the crushing component 3 and the first wall-breaking component 14 in the process of crushing the ginkgo leaves, the service life of the second shell 2, the crushing component 3 and the first wall-breaking component 14 is increased. Figure 1 to Figure 14As shown, the first shell 1 is installed outside the second shell 2, and the first shell 1 wraps the second shell 2, the crushing component 3 and the first wall-breaking component 14 inside, and forms a second cavity 8 between the outer wall of the second shell 2 and the inner wall of the first shell 1. Since the extraction solvent is generally methanol, ethanol or water, etc., which has good heat exchange performance, a second liquid input pipe 10 communicating with the second cavity 8 is installed on the first shell 1, and the other end of the second liquid input pipe 10 is connected to the extraction solvent source, and the extraction solvent is input into the second cavity 8, and heat is exchanged with the second shell 2, the crushing component 3 and the first wall-breaking component 14, so as to increase the temperature of the extraction solvent and reduce the temperature generated during the operation of the second shell 2, the crushing component 3 and the first wall-breaking component 14, so as to achieve the heating of the extraction solvent and reduce the temperature of the second shell 2, the crushing component 3 and the first wall-breaking component 14, which is beneficial to prolong the service life of the extraction device and is beneficial to energy saving and environmental protection.

[0065] Among them, Figure 1~Figure 3 As shown, the first motor 301 and the second motor 1401 are both located outside the first shell 1, and a motor bracket 4 is installed between the first motor 301, the second motor 1401 and the first shell 1. The first motor 301 and the second motor 1401 are installed on the first shell 1 through the motor bracket 4, and they do not contact the extraction solvent in the second cavity 8.

[0066] Specifically, Figure 1 to Figure 4 As shown, a liquid delivery component 9 is installed on one side of the first shell 1, and the liquid delivery component 9 can deliver the extraction solvent in the second cavity 8 to the first connecting pipe 6, and the first connecting pipe 6 then delivers the extraction solvent to the crushing component 3, and then the crushing component 3 injects the extraction solvent into the second shell 2.

[0067] Among them, Figure 1 As shown, the liquid delivery component 9 includes a first pump 901, on which a first liquid input pipe 902 and a liquid output pipe 903 are installed. The first liquid input pipe 902 is used to extract the extraction solvent in the second cavity 8, and is connected to the first connecting pipe 6 through the liquid output pipe 903. The extraction solvent enters the first connecting pipe 6 through the liquid output pipe 903 to complete the delivery of the extraction solvent.

[0068] like Figures 1 to 13As shown, since the ginkgo leaf powder is ejected from the connecting component by centrifugal force and high pressure, the second shell 2 is also provided with a liquid delivery component 9 to ensure that the ginkgo leaf powder entering the connecting component will not cause blockage. However, in the process of being broken by the crushing component 3, even if it is broken for a long time, there will be a very small part of the ginkgo leaves that may not be broken into ginkgo leaf powder that can pass through the connecting component. To solve the above problem, the interior of the first shell 1 is equipped with a second wall-breaking component 18, and the second wall-breaking component 18 can cross the liquid delivery component 9 to extract the ginkgo leaf powder that has not entered the first wall-breaking component 14 in the second shell 2 in the form of negative pressure, and can complete the crushing of the ginkgo leaf, so that the ginkgo leaf powder can meet the requirements of the extraction process. The second wall-breaking component 18 is located in the second cavity 8 formed by the first shell 1 and the second shell 2, immersed in the extraction solvent, and the heat generated in its crushing process can be heat-exchanged with the extraction solvent, while increasing the heat of the extraction solution, reducing the heat of the second wall-breaking component 18 itself.

[0069] Specifically, the second wall-breaking assembly 18 includes a second wall-breaking shell 1801, a partition 1802 is installed inside the second wall-breaking shell 1801, a third motor 1803 is installed at the lower end of the partition 1802, and a second wall-breaking blade 1804 matching the third motor 1803 is installed at the upper end. A material input pipe 1805 is installed between the second wall-breaking shell 1801 and the second shell 2, and the remaining ginkgo leaves in the second shell 2 are transported to the second wall-breaking shell 1801 through the material input pipe 1805. A first material output pipe 1806 is also installed on the second wall-breaking shell 1801, and the other end of the first material output pipe 1806 is connected to the third material output pipe 21, and the broken ginkgo leaves are transported to the steam extraction device 23 through the first material output pipe 1806. At this point, all the ginkgo leaves in the second shell 2 are broken and have undergone good wall-breaking treatment, so that the extraction solution is easier to interact with the ginkgo leaf powder, which is beneficial to the extraction of substances in the ginkgo leaves.

[0070] When in use, it is first necessary to open the sealing cover 202, add ginkgo leaves into the second shell 2 through the feed port 201, close the sealing cover 202, and start the gas delivery component 11 to discharge the gas in the second shell 2 to keep the second shell 2 in a vacuum state, and select a circulating gas mode, a nitrogen mode, a vacuum mode and other modes according to the process requirements.

[0071] Among them, the circulating gas mode does not need to evacuate the gas in the second housing 2 to a vacuum, but fills the second housing 2 with gas to keep the second housing 2 in a high pressure state. The gas enters the first transmission rod 302 through the first connecting pipe 6, and is ejected at high speed through the first nozzle 304, and contacts with ginkgo leaves during the ejection process to achieve the crushing of ginkgo leaves. After being crushed to a certain extent, the extraction solvent located in the second cavity 8 is extracted into the second connecting pipe 7 by the liquid delivery component 9, and is delivered to the first transmission rod 302 by the second connecting pipe 7, and is ejected at high speed through the first nozzle 304, and contacts with ginkgo leaf powder during the ejection of the extraction solution, and the crushing of ginkgo leaves is achieved, and the ginkgo leaf powder is beneficial to the mixing of the extraction solution. When the mixed solution in the second housing 2 is mixed to a certain extent, the first valve is opened, and the mixed solution in the second housing 2 is ejected into the first wall-breaking component 14 from the connecting component due to centrifugal force and high pressure. The first wall-breaking component 14 divides the solution in the second housing 2 into multiple portions, and performs wall-breaking treatment respectively, which can further improve the wall-breaking effect of ginkgo leaf powder, and is beneficial to the extraction of ginkgo leaf powder extract. When the mixed solution in the second housing 2 enters the first wall-breaking component 14 completely, the high-pressure gas in the second housing 2 can be extracted by the gas delivery component 11, and temporarily stored by the gas tank 12, and the sealing cover 202 is opened to add ginkgo leaf in the second housing 2. That is, the first wall-breaking component 14 and the crushing component 3 are two completely independent spaces, and the first wall-breaking component 14 and the crushing component 3 can operate independently, which is beneficial to improving the crushing efficiency of ginkgo leaf. After the wall-breaking is completed in the first wall-breaking component 14, the mixed solution in the first wall-breaking component 14 is transported to the steam extraction device 23 by the second material output pipe 20, the third material output pipe 21 and the fourth material output pipe 22, and final extraction is performed.

[0072] A method for extracting ginkgo leaf extract in one embodiment of the present invention comprises the following steps:

[0073] S1. Pretreatment: remove alkylphenol substances in ginkgo leaves that are allergic to humans and complete sterilization treatment; S2. Crushing: crush the pretreated ginkgo leaves, and then divide the crushed ginkgo leaves into multiple small portions, and perform wall breaking treatment on each portion; S3. Mixing: put the crushed ginkgo leaves and extraction solvent into a pure nitrogen environment, and stir the two to mix them evenly to obtain a ginkgo leaf mixture; S4. Extraction: perform multiple cycles of extraction on the ginkgo leaf mixture.
