Description

technical field [0001] The invention relates to the technical field of steviol glycoside extraction, in particular to a device for extracting notoginseng from Panax notoginseng and an extraction method thereof. Background technique [0002] Panax notoginseng is a precious medicinal material in my country. The famous and precious Chinese medicine "Sanqi" has the functions of promoting blood circulation and removing blood stasis, reducing swelling and pain, relaxing tendons and activating collaterals, among which it is famous for its hemostatic function. "Compendium of Materia Medica" states that "Sanqi stops bleeding, dissipates blood and relieves pain", and Sanqi has the reputation of "stopping bleeding without leaving stasis, removing blood stasis without hurting the body", and it is actually an important medicine for regulating blood. Physicians of the past dynasties have used Panax notoginseng as the top grade to stop bleeding, and are widely used for internal and externa...

Problems solved by technology

The water-soluble component of Panax notoginseng is a special amino acid isolated from the root of Panax notoginseng, which can shorten the coagulation time of mice and significantly increase the number of platelets, but there is no production of Panax notoginseng preparations yet and use

[0003] In the prior art, there are many reports about extracting notoginseng, and the patent of CN1865232A discloses a method for extracting notoginseng from notoginseng, through the alcohol solution extraction method, and then carrying out water extraction treatment, adding ethanol precipitation to the aqueous solution, filtering To remove impurities, the aqueous solution is extracted with n-butanol, and the combined water phase is directly polymerized with styrene and diethylbenzene as monomers. Crystallization obtains notoginseng with higher purity, but the temperature is room temperature during water extraction, which leads to longer water extraction time, and the notoginseng is not pulverized when water extraction is carried out, and the efficiency of water extraction is low, which reduces the Extraction Efficiency of Panax notoginseng

[0004] The patent of CN107162926A discloses a method for extracting notoginseng, which uses industrial notoginseng waste residue as raw material to extract notoginseng, and when the product obtained by the thin layer detection method is verified to contain notoginseng during the extraction process, the follow-up process is continued. Purification, crystallization and other follow-up steps, after purification and TLC detection, the eluate with only one spot and the same Rf value corresponding to the notoginseng reference substance was combined and crystallized, but ethanol and concentration were not used during the extraction process The liquid is stirred and mixed, resulting in more impurity content in the crude extract of Panax notoginseng

[0005] The patent of CN1414009A discloses a kind of notoginseng extraction method, the notoginseng raw powder is leached with methanol, obtains methanol extract and residue, the residue of notoginseng raw powder is extracted with water after methanol extraction, obtains water extract, and water extract is extracted with water. Extraction with n-butanol, freeze-drying the water layer to obtain the crude extract of notoginseng, further separation and purification of the crude extract of notoginseng to obtain notoginseng, but the crude extract of notoginseng was not removed, resulting in the purified notoginseng crude extract There are many impurities in seven elements, which affect the quality of notoginseng

[0006] In summary, when the existing technology extracts notoginseng, there will be incomplete crushing of notoginseng and no heating of the extraction solution, resulting in low efficiency of water extraction, resulting in a low extraction rate of notoginseng; the extraction process The ethanol and the concentrated solution were not stirred and mixed, resulting in more impurity content in the crude extract of notoginseng; the crude extract of notoginseng was not removed, resulting in higher impurity content in notoginseng, which had a negative impact on product quality Influence, for this reason, we have proposed a kind of device and extraction method of notoginseng from Panax notoginseng, to solve the above problems
