Abstract: The contents of polysaccharide in leaves of Morus alba L. were measured by anthrone-H2SO4 colorimetry.Wavelength for measurement was 620nm and converting factor of polysaccharide was 3.07;Good linearity ranged from 10~60μg/ml,r=0.999005;Average recovery rate of polysaccharide was 98.81% with 2.08% of RSD(n=5). The results showedthe highest content of polysaccharide was in leaves of Morus alba L. collected at Oct.; The method used in this paper was simple,accurate and stable. It can be used for determination of the polysaccharide in leaves of Morus alba L..

Key words: leaves of Morus alba L., polysaccharide, anthrone-sulfuric acid determination
