Abstract

The invention provides a method for comprehensively extracting polysaccharides, polyphenol and saponin from camellia oleifera abel defatted cakes. The method includes the following steps: obtaining polysaccharides through aqueous extraction, concentration, deproteinization and ethanol precipitation after the camellia oleifera abel defatted cakes are degreased; concentrating and adding salt into the supernatant after the ethanol precipitation of the polysaccharides, and performing extraction to obtain the polyphenol through ethyl acetate; and absorbing and analyzing the aqueous phase after extraction of the polyphenol through resin to obtain the saponin. According to the method, effects of substances such as the polysaccharides and the polyphenol during extraction of the saponin are overcome, and the purity of the saponin is improved; and the polysaccharides, the polyphenol and the saponin are obtained, and the defect of low utilization rate of camellia oleifera abel defatted cakes in the existing methods is overcome.

Description

technical field

[0001] The invention relates to a method for comprehensively extracting polysaccharides, polyphenols and saponins from camellia oleifera, and belongs to the field of extraction and deep processing of active ingredients of camellia oleifera. Background technique

[0002] Camellia ( Camellia oleifera Abel. ) belongs to the genus Camellia in the family Theaceae, and is mainly distributed in southern regions such as Guangxi, Hunan, and Jiangxi in my country. It is one of the four traditional woody oil plants that are as famous as olives, oil palms, and coconuts. Camellia oleifera is the residue left after oil extraction of camellia oleifera fruit, also known as tea seed cake, tea bran and other names. Camellia oleifera is a by-product of tea oil production, its yield is nearly three times that of camellia oil, and it is rich in biologically active substances such as saponin, polysaccharides, and polyphenols, and has good development and utilization in the fields...
