Method for extracting ginsenoside from American ginseng

Abstract

The invention belongs to the technical field of medicine and discloses a method for extracting ginsenoside from American ginseng. The method comprises the following steps of performing superfine grinding on American ginseng, sieving with a 100-400-mesh medicinal sieve, adding a lignin degrading enzyme with the activity of 50-80U / mL for enzymolysis for 0.5-1.5h at 55-65 DEG C, filtering, adding residues into 65-80% alcohol for leaching for 2-3 times, filtering, concentrating filtrate at reduced pressure, drying, and obtaining a ginsenoside crude product. According to the method, the superfine grinding and enzyme treatment are combined, so that the efficiency and amount of extracting the ginsenoside from the American ginseng are improved and increased.

Description

technical field

[0001] The invention belongs to the technical field of medicine and relates to a method for extracting traditional Chinese medicines, in particular to a method for extracting ginsenosides from American ginseng. Background technique

[0002] American ginseng (Panax.quinquefolium L., English name: American Ginseng), also known as American ginseng, Cantonese ginseng, American ginseng, American ginseng, is the dried root of American ginseng, a plant of Araliaceae. Ginsenoside is one of its main active components, which has anti-fatigue, hypoxia resistance, immune regulation, anti-tumor effects, among which ginsenosides Rg1, Re, and Rb1 are regarded as the representative components of American ginseng.

[0003] At present, the extraction of ginsenosides mainly adopts water extraction and alcohol precipitation method, heating reflux method, microwave extraction method and ultrasonic extraction method. However, the traditional extraction method has defects such as ...
