| Abstract: | To establish the method for determination of polysaccharide from Rhizoma of Osmunda japonica and the content of polysaccharide from Rhizoma of O. japonica in different locations and different harvest times was compared. Method: Sulfuric acid-phenol method was used and the sugar content was determined by the spectrophotometer at 490 nm. Result: The content of polysaccharide from Rhizoma of O. japonica in different locations was 1.22%-1.85% and in different harvest times was 0.91%-1.37%. Conclusion: The different locations and different harvest times would affect the content of polysaccharide from Rhizoma of O. japonica. |
