【Abstract】 Objective: To study the chemical constituents from the whole plants of Polygala telephioides.Method: Compounds were isolated by repeated silica gel and Sephadex LH-20 column chromatography,and their structures were determined by spectral analysis and physicochemical properties.Result: Six xanthones were isolated from P.telephioides,and their structures were identified as 1,3,7-trihydroxyxanthone(1),1,7-dihydroxy-3-methoxyxanthone(2),1,3-dihydroxyxanthone(3),1,7-dihydroxyxanthone(4),1-methoxy-2,3-methylenedioxyxanthone(5) and 1,7-dimethoxyxanthone(6).Conclusion: All the compounds were obtained from this plant for the first time.更多还原
