Abstract

The invention provides a method for extracting, separating and purifying formononetin and calycosin from Astragalus mongholicus waste residue. The technical scheme adopted in the invention is as follows: taking waste residue after the production and process of astragalus injection as a raw material; adopting a series of original and efficient technologies for extracting, separation and purifying such as homogenate extraction-mixing enzyme induction biotransformation technology, negative pressure cavitation extract technology, liquid-liquid extraction technology, macroporous absorption resin enrichment technology, normal phase silica gel medium pressure column chromatography technology and devitrification at a low temperature, recrystallization technology and the like to obtain the formononetin and calycosin with high purity, wherein the purity thereof can be more than 95%, and the yield is 80-95%. The raw material used in the invention is the waste residue in the industry production, and the process of the method is simple and practicable, has small pollution to the environment; the obtained formononetin and calycosin have low production cost, high purity and yield, good repeatability, high utilization effect of Astragalus mongholicus resources and the like; and the method is suitable to scaled industrial production.

Description

technical field

[0001] The present invention relates to a method for extracting, isolating and purifying functional active ingredients astragalus isoflavones from astragalus waste residue, in particular to a method for extracting, separating and purifying formononetin and calycosin from waste residue of astragalus injection produced and processed . Background technique

[0002] Astragalus membranaceus (Fisch.) Bunge var. mongholicus (Bunge) Hsiao or Astragalus membranaceus (Fisch.) Bunge dry roots. According to the Pharmacopoeia, Astragalus is sweet in taste and slightly warm in nature. It has the functions of enhancing the body's non-specificity, improving heart function, dilating coronary arteries, diuresis and detumescence, benefiting health and solidification, promoting granulation of sores, antibacterial, antiviral, anti-fatigue, anti-aging, Promote hematopoietic function, protect the liver and other effects. It is often used for qi deficiency and fatigue, lack of fo...
