Abstract
Objective: To establish an analysis method for the determination of the content of polysaccharides from Prunus mume. Method: Using Phenol-sulfuric Method to determination of the content of polysaccharides for P.mume. Result: The absorbance was determined at 488 nm. The linear curves was fine between the concentration rang of 0.02-0.2 g ·L-1 (r=0.999 8)
the average recovery was 100.38%
the RSD was 0.892%.The content of polysaccharide in P.mume was 2.51%. Conclusion: Phenol-sulfuric method is a simple operation process with accurate result
laying a foundation for further study on polysaccharides in P.mume.
