Comparison of methods in determination of polysaccharide in Lycium barbarum L.
Objective: To compare difference in determination content between phenol -vitriolic colorimetry method and anthrone sulphuric acid colrimetry method for polysaccharides in Lycium barbarum. Methods: Above two methods were employed to determine content of polysaccharides by UV spectrophotography. Results: The determination value of anthrone-sulphuric acid colorimetry method is high than the phenol-vitriolic colorimetry method, and its values dissimilarity have statistical significance between two methods.Conclusion: The result of phenol-vitriolic colorimetry method is more reliable and accurate, it can be considered as the optimum assay method for polysaccharides in Lycium barbarum.
