Embodiment 1
[0024] The overall preparation process of the three chemical component groups of Schisandra chinensis:
[0025] (1) Wash Schisandra chinensis, dry at 50°C for 36 hours, pulverize, and pass through a 30-mesh sieve;
[0026] (2) Heat and reflux the pulverized Schisandra chinensis with 10 times the amount (weight ratio) of distilled water to extract twice, each time for 3 hours, filter, combine the water extract, and concentrate under reduced pressure to a density of 1.05;
[0027] (3) Dry the residue after water extraction at 50°C, heat and reflux extraction with 5 times the amount (weight ratio) of 90% ethanol for 3 times, each time for 2 hours, filter, combine the alcohol extracts, and concentrate under reduced pressure to a density of 1.05;
[0028] (4) adding 95% ethanol to the water extract, adjusting the alcohol concentration of the extract to 80% (volume ratio), fully stirring the precipitate, and standing for 12 hours;
[0029] (5) filter to obtain the precipitate and s...
Embodiment 2
[0035] In this embodiment, if petroleum ether (boiling point is 60-90° C.) is refluxed for 1 hour for precipitation, then vacuum-dried for 12 hours, a light red powder is obtained, which is a crude polysaccharide extract with a crude polysaccharide content of 60-75%.
Embodiment 3
[0037] For example, the precipitate is refluxed with petroleum ether (boiling point: 60-90°C) for 1 hour, then refluxed with ether for 1 hour, and vacuum-dried for 12 hours to obtain a white powder, which is a crude polysaccharide extract with a crude polysaccharide content of 75-95%. .

Abstract
The invention belongs to the technical field of medicine and discloses three extracts of chemical compound groups of Chinese magnolia vine and a preparation technology thereof. The invention is characterized by drug ingredients saving and less toxicity. The three extracts are respectively crude amylose extract, total organic acid extract and total Lignans extract, wherein, the weight content of the crude amylose extract is between 50 and 95 percent, the weight content of the total organic acid is between 50 and 70 percent and the weight content of the total Lignans content is at least 50 percent. The Chinese magnolia vine is crushed, screened, distilled, filtered, deposited, absorbed and eluted, and then the eluted liquid is gathered and concentrated, thus, the extract is obtained. The preparation method has simple technology and the content is stable.
Description
technical field [0001] The invention belongs to the technical field of medicine, and relates to extracts of three chemical component groups of schisandra chinensis and a preparation process thereof. The total content of the chemical components of the three extracts obtained according to the preparation process can reach more than 50%. Background technique [0002] The water-soluble components of Schisandra chinensis are mainly polysaccharides and organic acids, and the fat-soluble components are mainly lignans. These three chemical composition groups all have definite pharmacological effects. Polysaccharides have liver protection, anti-fatigue, immune promotion, anti-oxidation, anti-aging and anti-tumor effects; organic acids have expectorant and antitussive effects; the pharmacological effects of lignans involve the digestive system, cardiovascular system, and central nervous system , reproductive system and anti-oxidation, anti-aging and other aspects. (Chinese Materia M...
