WEI Yong-sheng, ZHENG Min-yan,CAO Lei(Department of Chemistry,Xianyang Normal University,Xianyang,Shaanxi 71200,China)  
The soluble polysaccharides in Fagopyrum esculentum Moench were extracted by the traditional method of boiling with water and depositing in alcohols.After removing proteins,the content of polysaccharides was determined by phenol-sulfuric acid method with glucose as standard sample.The result showed that there were favorable linearity relationship between the absorption and content determined in the range of 1~10mg/L at the wavelength of 489nm.The content of polysaccharides was about 4.31%.
