Abstract

The invention discloses an extraction process and application of ginseng polypeptide. The extraction process comprises the following steps: S1, pretreatment; S2, crushing; S3, extraction; S4, separation; S5, filtration; and S6, disinfection, wherein a filter membrane used in the step S5 is an alumina carrier prepared by using a specific method and is connected with a covalent organic skeleton filter membrane. Through adjustment of the geometric structure of a covalent organic skeleton and selection of different construction units for adjustment of the pore size and pore shape of the covalent organic skeleton, the filter membrane best suitable for separation of ginseng polypeptide is prepared, and high-efficiency separation and extraction of ginseng polypeptide are realized.

Description

technical field [0001] The invention belongs to the field of ginseng polypeptide preparation, and in particular relates to an extraction process and application of ginseng polypeptide. Background technique [0002] Ginseng has a very special position in the history of Chinese medicine. It is known as the "king of Chinese herbal medicine" and is the representative of Chinese traditional medicine. Modern medical research has proved that ginseng has a good protective effect on the central nervous system, cardiovascular system, respiratory system, blood and hematopoietic system, endocrine system and reproductive system. In addition, studies have proved that ginseng also has significant anti-tumor, anti-radiation, anti-aging and detoxification effects. In the past 30 years, with the development of chemical analysis methods, great progress has been made in the separation, purification and structural identification of ginseng components. It is known that ginseng root contains act...
