Abstract: This paper reported a study on the purification and preliminary analysis of polysaccharides of Opuntia Vulgaris Mill. The coarse polysaccharides yield 4.62% has been obtained from the old Opuntia Vulgaris Mill. The coarse polysaccharides of the tender Opuntia Vulgaris Mill was 4.10%. The yield is muchmore than the yield of Angelica sinensis Dids. and Lycium chinense Mill. The component sugars after hydrolysis of the polysaccharide were identified as glacose, arabinose, Xylose and rhamnose. It could be separated into oneneutralfraction(A)and two acidic fractions(B, C), observed with themethod of DEAE-Dextran Gel A-25 chromatography. The sugars of each part are 17%-43%.
