Determination of Polysaccharides from Lycium Rethenicum Murr with the Method of H2 SO4 -Phenol
Objective:To test the content of Polysaccharides from Lycium rethenicum Murr with the method of H2 SO4 -Phenol.Methods:Adopt the ultraviolet spectrophotometer with blank group and glucose group.Re-sults:There was a good linear relationship between the content of polysaccharides and the absorbance within the range of 0.10mg, and the average recovery rate was 100.72% and RSD was 2.49%.Conclusion:The method is simple,accurate,reproducible and can be used as a quality control method for Lycium rethenicum Murr.
