[Studies on content determination of polysaccharides in Periploca forrestii] [English Abstract, Journal Article]
Zhongguo Zhong Yao Za Zhi 2009 May; 34(10):1241-4.
OBJECTIVE: To establish a method for content determination of polysaccharides in Periplocaforrestii.
METHOD: The conversion coefficient of P. forrestii. polysaccharide to glucose was obtained by refined polysaccharides, and then the content of crude polysaccharides was determined by sulfuric-phenol method.
RESULT: The content of crude polysaccharides in P. forrestii. was 54.68% (RSD 3.0%, n = 6), and the average recovery was 101.7% (RSD 6.0%, n =6).
CONCLUSION: The method was simple, rapid, and accurate.
