Abstract

The invention discloses a process for separating and extracting angelica polysaccharide and application thereof. The process comprises the following steps: directly extracting angelica sinensis crude powder by water, precipitating by using 95% ethanol to obtain crude polysaccharide after concentrating an extracting solution; adding saturated Ca(OH)2 to remove protein after dissolving the crude polysaccharide by water; processing by strong acid cation exchange resin (SACER) and strong-base anion exchange resin (SBAER) respectively; dialyzing by using a dialysis bag after concentrating, so as to obtain the angelica polysaccharide after concentrating. The extraction and separation method disclosed by the invention is simple and feasible, the obtained neutral angelica polysaccharide is high in purity, and the angelica polysaccharide has a significant increasing effect on peripheral blood white blood count (WBC) and LC in mice. Thus, theoretical direction and an experiment basis are provided for further research of the mobilization action of the angelica polysaccharide on hydrogenated soy phosphatidylcholine (HSPC).

Description

technical field [0001] The invention belongs to the technical field of natural medicines, and in particular relates to a process for separating and extracting polysaccharides from Angelica sinensis and its application. Background technique [0002] Angelica sinensis is the dried root of Angelica sinensis diel, which is mainly produced in Minxian County, Gansu, Yunnan, Sichuan, Shaanxi, Hubei and other places in China. Angelica is sweet, pungent, and warm in nature. It is a well-known and commonly used traditional Chinese medicine. It has the effects of nourishing blood and promoting blood circulation, regulating menstruation, relieving pain, and laxative. . With the in-depth research on Angelica sinensis and the application of new technologies, a variety of chemical active ingredients have been isolated: ligustilide, ferulic acid, angelica polysaccharides, trace elements, vitamins, amino acids, chalcone, Semiterpenes, alkyne compounds. In recent years, the promotion of he...
