The extraction technology of soluble polysaccharides from Siraitia grosvenorii(Swingle) C.Jeffrey and its constituents analysis were studied.Polysaccharides of Siraitia grosvenorii(Swingle) C.Jeffrey was extracted with hot water and precipitated by alcohol,in which the fat,simple saccharides and protein were removed with petroleum ether,80% alcohol and the Sevag method,respectively.The optimum condition of extracting polysaccharides from Siraitia grosvenorii(Swingle) C.Jeffrey was the ration of 1(Siraitia grosvenorii)∶30(distilledwater),80 °C for two times and for 4 h once time.The polysaccharides were made of D-glucose,D-galactose,D-xylose,Larabinose,L-rhamnose and glucuronic acid.
