Abstract:Objective:To study the tannins from Tripterygium hypoglaucum. Method:Compounds were isolated by column chromatography and elucidated on the basis of spectroscopic analysis and comparison of references. Result:The compounds obtained were determined as (+)catechin,(-)epigallocatechin,procyanidin B-3,procyanidin B-4 and gallocatechin (4α→8)epicatechin.Conclusion:All the compounds were obtained from this plant for the first time.
