Abstract:Objective:To purify and determine the contents of polysaccharide in Morus alba L.Methods:The polysaccharide were preliminarily purified by 10% trichloroacetic acid and resin.The contents of polysaccharide were determined by sulfuric acid anthrone method and detected at 620 nm by UV/Visible spectrophotometry.Results:The average contents of polysaccharide in Morus alba L.was 2.62%.The recovery rate was 98.81% with 2.08% of RSD(n=5).Conclusion:The sulfuric acid anthrone method is reasonable.
Keywords:Morus alba L  Polysaccharide  Purification  Sulfuric acid anthrone
