Objective To isolate and identify the structures of the phenolic compounds from Geum aleppicum Jacq..Methods The structures of six compouds were determined by the physical and chemical data and spectroscopic analysis after the purification by thin-layer chromotography and silical gel column chromatography.Results Six phenolic compounds were isolated from Geum aleppicum Jacq.,and their structures were established to be benzoic acid(Ⅰ),gallate acid(Ⅱ),salicylic acid(Ⅲ),vanilin(Ⅳ),3,4,5-trihydoxybenzoic dehyde(Ⅴ) and 3,4,5-trihydoxybenzoic acid,ethyl ester(Ⅵ).Conclusion The compounds Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ,Ⅵ are isolated from this plant for the first time.
