[0002] Wine culture has a long history, and wine has been loved by the general public since ancient times. In today's society, drinking alcohol for social events, festivals, gatherings with friends and relatives, and a drink during meals has become a normal thing. After entering the human body, alcohol will be quickly absorbed and accumulated in the blood and various tissues (especially brain tissue, whose alcohol concentration is about 10 times that of blood). Only a very small amount of alcohol can be directly excreted from the body, and most of it still needs to be metabolized by the liver. Acute excessive drinking can cause symptoms such as headaches, dizziness, vomiting, inattention, memory loss, and emotional instability. Alcohol has both advantages and disadvantages for the body. The key lies in the amount of alcohol consumed. The body absorbs a certain amount of alcohol, but people who drink often exceed the scope of quantity. Excessive alcohol will damage the stomach and increase the burden of liver detoxification. Long-term drinking will cause permanent liver damage.

[0003] Currently, there are many kinds of products for sobering up and protecting the liver, most of which are medicines or hormone medicines. Many medicines, fruits, Chinese medicines, etc. have certain sobering up effects, but products with different sobering up formulas have different effects on sobering up. Existing products are difficult to meet conventional sobering up needs and are inconvenient to carry. Therefore, how to provide a product with efficient sobering up and protecting the liver and easy to carry is a problem that needs to be solved urgently by technical personnel in this field. Summary of the invention

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with 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 are within the scope of protection of the present invention.

[0036] Example 1

[0037] Liquid A is directly selected from the 3-fold concentrated roxburghii stock solution from the factory, and the pH is adjusted to between 4 and 5.5 with food sodium bicarbonate;

[0038] Preparation of Solution B:

[0039] (1) Material selection: Select the preferred materials that have medicinal effects and are edible, including Dendrobium officinale, Hovenia dulcis, Pueraria root, Cornus officinalis, Chicory, Polygonatum sibiricum, Crataegus pinnatifida and Sugarcane.

[0040] (2) Crushing: According to the characteristics of the materials themselves, Dendrobium officinale, Pueraria root, Hovenia dulcis, and Chicory were ground into powder using a crusher, sugarcane was squeezed into juice using a juicer, and Cornus officinalis, Polygonatum sibiricum, and Hawthorn were cut into 1x1 cm blocks;

[0041] (3) Soaking: Add pure water to the powder and block materials to cover the materials by 2 to 3 cm, and soak for 30 minutes to allow the materials to fully absorb water. The texture of the materials will become softer, shorten the cooking time, and the effective ingredients will be more easily dissolved in water;

[0042] (4) Decoction: After soaking, add 40 to 50 times the weight of water into a special container and boil it. Heat it with rapid fire. After boiling, simmer it with slow fire for 80 minutes. Decoction to a certain ratio of ingredients to water: 1g:30mL of Dendrobium officinale, 1g:20mL of Hovenia dulcis, 1g:20mL of Pueraria root, 1g:20mL of Cornus officinalis, 1g:20mL of Cichorium indica, 1g:20mL of Crataegus pinnatifida, 1g:20mL of Polygonatum sibiricum;

[0043] (5) Compounding: Through a large number of experimental proportions and tastings, and then through single-factor experiments to determine the formula combination, the formula ratio with the best taste, flavor, and color is obtained, that is, the following components in weight percentage: 35% of roxburghii (liquid A), 17% of dendrobium officinale, 2.8% of hovenia dulcis, 11.2% of kudzu root, 11.5% of cornus officinalis, 5.5% of chicory, 3% of hawthorn, 5.5% of polygonatum, and 8.5% of sugar cane; after mixing, a composite liquid is obtained;

[0044] (6) Concentration: The composite solution is concentrated by using a vacuum concentrator at 0.08 MPa, 30 rpm, and 55° C. to a concentration of 4 to 6 times;

[0045] (7) Centrifugation: Centrifuge at 5000 rpm for 5 min to remove impurities in the liquid;

[0046] (8) Packaging: Based on the body's alcohol intake of 8 ml / kg, the dosage of oral liquid is 15 ml. For an adult weighing 60 kg, 480 ml is required to achieve a better effect. This oral liquid is concentrated 3 to 6 times, so a 50 ml special bottle is selected for packaging;

[0047] (9) Sterilization: circulating steam sterilization, temperature 100°C, time 15-30 min;

[0048] Bottle structure Figure 1 As shown: comprising: a bottle body 7 and a matching bottle cap 3, wherein the bottle body 7 is divided into a liquid A storage area and a liquid B storage area by a closely connected partition 1 5 and a partition 2 6, wherein the partition 1 5 is provided with a through hole 1, and the partition 2 6 is provided with a through hole 2, and the positions of the through hole 1 and the through hole 2 are not opposite;

[0049] A bevel gear 1 is disposed inside the bottle cap 3, and a bevel gear 2 is disposed on the side wall of the bottle body 7 in the B liquid storage area, and the bevel gear 1 and the bevel gear 2 are meshed;

[0050] An L-shaped shaft is connected to the center of the bevel gear 2, and the end of the L-shaped shaft is connected to the crank slider mechanism 4. The end of the crank slider mechanism 4 is fixed to the center of the partition 1 5.

[0051] Principle of bottle packaging: when the bottle cap 3 is twisted, the bevel gear 1 rotates accordingly, thereby driving the bevel gear 2 2 meshing with it to rotate, and converting the rotation of the bottle cap 3 along the circumferential direction of the bottle body into the rotation of the bevel gear 2 2 along the axial direction of the bottle body. The bent part at the end of the L-shaped shaft connected to the bevel gear 2 2 serves as a crank, connected to a crank slider mechanism 4, and the slider of the crank slider mechanism 4 is fixed as a whole with the partition 1 5. When the rotation of the bevel gear 2 2 along the axial direction of the bottle body drives the crank to rotate, the partition 1 5 connected to the crank slider mechanism 4 moves upward along the axial direction of the bottle body, converting the rotation of the bevel gear 2 2 along the axial direction of the bottle body into the direct motion of the slider along the axial direction of the bottle body, thereby separating the partition 1 5 and the partition 2 6. The left half of the partition 1 5 has a through hole, and the right half of the partition 2 6 has a through hole. When the two partitions are in contact, the through holes complement each other, and liquid A is separated from liquid B. When the two partitions are separated, the through holes of the two partitions flow, and liquid A is mixed with liquid B.

[0052] Experimental example:

[0053] 1. Flavonoid content determination test

[0054] (1) To prepare a standard curve, 10 mg of rutin standard was completely dissolved in 70% (v / v) ethanol, the volume was fixed to 50 mL, and the solution was shaken to obtain a 0.2 mg / mL rutin standard solution.

[0055] (2) Take 0, 1.0, 2.0, 3.0, 4.0, 5.0, and 6.0 mL of rutin standard solution, and add 1 mL of 5% (m / v) NaNO2 solution, 1 mL of 10% (m / v) Al(NO3)3 solution, and 10 mL of 4% (m / v) NaOH solution in sequence. Each addition of reagents requires 6 minutes of reaction. Finally, add 70% (v / v) ethanol to 25 mL and let stand for 30 minutes. Use 70% (v / v) ethanol as the blank solution, measure the absorbance at 510 nm, and obtain the standard curve y=0.0121x+0.0016(R 2 =0.9994).

[0056] (3) Determination of flavonoids in samples: 1.0 mL of the sample solution prepared in Example 1 was taken, and the absorbance was measured at 510 nm according to the above steps. The flavonoid content of the sample (mgRE / 100 mL) was calculated according to the standard curve.

[0057] The results of the flavonoid content test are as follows (among the active ingredients of the oral solution, flavonoids mainly come from four raw materials: Rosa roxburghii, Dendrobium officinale, Pueraria lobata, and Hovenia dulcis):

[0058] Flavonoid content of four raw materials in standard 50ml oral solution

[0059] type Proportion (%) Volume after concentration (mL) Flavonoid content (mg) Rosa roxburghii 35 17.5 255.850 Dendrobium 17 8.5 3.840 Pueraria root 11.2 5.6 6.152 Zhizizi 2.8 1.4 8.311

[0060] In summary, the content of flavonoids in the oral solution is approximately 548.306 mg / 100 ml.

[0061] 2. Effect test:

[0062] An average of 15 male and female interns and graduate students aged 20-27 were selected as the subjects. Criteria: (1) Informed consent to the content and purpose of the experiment and voluntary participation in the experiment; (2) Healthy and without cardiovascular and cerebrovascular diseases.

[0063] Test method: drink 100mL of 53° liquor at one time, then drink the oral solution and rinse your mouth. After 5 minutes, blow into a special alcohol tester (produced by Shenzhen Zhaowei Technology Co., Ltd.) every 15 minutes to test, and immediately convert it into blood alcohol concentration. Record the data. Randomly select 6 people from 30 test personnel to calculate the average data as a group of data, and draw a blood alcohol concentration time change graph. The results are shown in the attached figure. Figure 2-5 As shown. (Sample 1 is a 3-fold concentrated oral liquid for alcohol detoxification and liver protection, and Sample 2 is a 4-fold concentrated oral liquid for alcohol detoxification and liver protection). Figure 1-5 They respectively represent the blood alcohol concentration data graph changes of the oral liquid packaging bottle and the test subjects after drinking alcohol but not drinking the oral liquid, and the blood alcohol concentration data change graph after drinking alcohol and drinking the oral liquid at the same time.

[0064] In summary, the test results show that the oral liquid has a certain effect of sobering up when the test subjects do not drink the oral liquid after drinking alcohol and when the test subjects drink the oral liquid after drinking alcohol at the same time.
