Abstract

The invention discloses a preparation method of taxus chinensis extractive. The preparation method comprises the following steps: (1) preparing a taxus chinensis raw material; (2) conducting ultrasonic wall-breaking treatment, soaking the taxus chinensis raw material in a soaking agent in a stirring manner to obtain a soak solution, and conducting the ultrasonic wall-breaking treatment on the soak solution to obtain a material liquid; (3) performing enzymolysis: transferring the material liquid to a reaction container, adding neutral protease which is 0.3-1.0% of the taxus chinensis raw material in weight to the reaction container, obtaining a mixed liquor, regulating the pH value of the mixed liquid to 6.8-7.0, conducting enzymolysis to hydrolyze free proteins in glycoprotein and glycan, deactivating enzyme, and obtaining a pulp liquid; (4) conducting reflux extraction on the pulp liquid to obtain an extracting solution, filtering and concentrating the extracting solution to obtain a concentrated solution, and filtering the concentrated solution to obtain a filter liquor; (5) conducting spray drying to obtain the taxus chinensis extractive. The preparation method increases the dissolution rate and accelerates the extraction rate.

Description

technical field [0001] The invention relates to a preparation method of a yew extract, and also relates to the application of the yew extract, which belongs to the field of medicinal plant development. Background technique [0002] Taxus is the general name of Taxus genus Taxus. The medicinal value of yew has been recorded in "Compendium of Materia Medica", and it is mainly used for the treatment of cholera, typhoid and for detoxification. It is recorded in "Modern Dictionary of Traditional Chinese Medicine" and "Materia Medica Tui Chen" that its nature and taste are bitter, flat, and slightly poisonous. Modern Chinese medicine also uses it to treat diabetes, kidney disease and gynecological diseases. More than 400 compounds have been isolated from yew plants, the main components are taxanes and non-taxanes. Taxanes are taxane diterpenoids, and non-taxanes are mainly triterpenes, steroids, homoterpenes, flavonoids, phenylpropanoids, and phenols. In my country's tradition...
