Abstract:The content of polysaccharides in Artemisia capillaries Thunb was determined by oxybenzene-sulfuric acid colorimetry in 490nm,Conversion factor of polysaccharides f=1.3214,Between 10ug/ml and 50ug/ml absorbance and the content have good linear relation(r=0.9998),The average recoveries were 99.76%,Precision RSD% were 1.24%,The content of polysaccharides in Artemisia capillaris Thunb reaches 7.0%
Keywords:Artemisia capillaries Thunb  polysaccharides  Determination
