Study on the Extraction and Purification of Polysaccharide from Schisandra Chinensis(Turcz) Baill Fruit

In this paper,two polysaccharides verified by UV-VIS and infrared spectroscopy,were obtained through the following steps:ext raction,ethanol precipitation,deproteinization,decolorization and column chro matography by DEAE cellulose. Quantification result of polysaccharide in Schisan dra Chinensis(Turcz)Baill Fruit show that crude polysaccharide content percent age in it is 6.1%, the three extraction ratio are 55.6%,38.5% and 4.8% respectiv ely ,the loss of crude polysaccharide during deproteinization by Savage method i s 7.2% and the percentages of the pure polysaccharides in Schisandra Chinensis (Turcz ) Baill Fruit are 0.387% and 0.06% .
