Abstract:
AIM: To measure and compare the content of glycyrrhizic polysaccharides in Glycyrrhiza in three different growth time. METHODS: The contents of polysaccharides were determined by phenol-sulfuric acid method and by reference to glucose, and wavelenth in spectrophotometer was set at 490 nm. RESULTS: There was difference of the content of the extracted polysaccharides among Glycyrrhiza for 1, 2 and 3 year, amounted to 11.75%, 11.07%, 7.88%, respectively. CONCLUSION: Annual glycyrrhiza appeared to be the appropriat crude drug for polysacchrides content. 1.Colle
