| Abstract: | The active polysaccharide (non-starch) in Hovenia acerba Lindl.is extracted by boiling water-ethanol.The content of polysaccharide in Hovenia acerba Lindl.is 13.83%.Through anthrone-H_2SO_4 colorimetry method the polysaccharide was measured at wavelength 568 nm with a recycle rate 99.20% and RSD 1.13%.The results indicated that this method is simple,recurring and very stable. |
