Description

technical field

[0001] The invention relates to a method for extracting polysaccharides in Astragalus membranaceus by using enzyme treatment. Background technique:

[0002] Radix Astragali (Radix Astragali) is the dried root of Astragalus membranaceus (Fisch) Bge.Var.mongholicus (Bge) Hsiao. or A. membranaceus (Fisch) Bge. of the leguminous plant Astragalus membranaceus (Fisch) Bge. Astragalus polysaccharide is one of the main components of Astragalus, which has a wide range of pharmacological effects.

[0003] The traditional method of extracting astragalus polysaccharides is mainly direct water extraction or water extraction after degreasing. The medicinal part of astragalus is the root, in which there are more cellulose, hemicellulose and lignin, and the release of active ingredients during the extraction process has a greater impact. hindering effect, so the extraction rate is low. Although newer extraction methods such as ultrasonic or microwave methods have certain e...
