Abstract

The invention provides a method for extracting saponin in plants through microbial fermentation. The method comprises the following steps: firstly, extracting saponin in sapindus mukurossi peel and Chinese honeylocust fruits by using deionized water, respectively removing impurities in an extracting solution by using deionized water and an ethanol solution, then degrading saccharides, proteins, pectin, cellulose and other substances in the extract by adopting microorganism yeast, and finally, further purifying the saponin in the extract by utilizing cation exchange resin and AB-8 macroporous adsorption resin in sequence, so that the saponin yield and the purity of the saponin in the extract can be improved to the maximum extent. In addition, due to the fact that the saponin shows certain weak alkalinity, the saponin can be salified and dissolved in an acid solution and can be precipitated under an alkaline condition. Therefore, the saponin is refined by adopting a hydrochloric acid ethanol-ammonia water precipitation method, and the preparation method is simple to operate, and is scientific and reasonable. The saponin extracted by the method of extracting saponin in plants throughmicrobial fermentation can be directly used in various cleaning agent products.

Description

technical field [0001] The invention relates to a method for extracting saponins from plants, in particular to a method for extracting saponins from plants by microbial fermentation. Background technique [0002] Soapberry, also known as hand-washing fruit or round soap, is distributed in vast areas such as Southeast Asian countries, and it has a wide range of applications in greening, soil and water conservation, and environmental protection. With the in-depth study of Sapindus chinensis, its chemical composition and pharmacological effects have been gradually discovered, which has attracted more and more attention. Sapindus saponin is mainly distributed in the skin of Sainberry, which is an excellent natural surfactant. Sapindus saponin not only has good emulsifying, dispersing, foaming, moisturizing effects, but also has bactericidal, analgesic, and anti-inflammatory properties. , insecticidal and blood pressure lowering effects. As a natural active substance, Sapindus ...
