Abstract: 【Objective】There is a rich resource of Tephrosia purpureain China.The chemical components from different parts of T.purpureawere investigated in order to explore their structures.【Methods】The chalcones were isolated and purified by column chromatography on silica gel,and their structures were identified by spectral analyses and compared with literature.【Results】Eleven chalcones chemical components were obtained from the branches and leaves of T.purpurea and characterized as:elatadihydrochalcone(1),spinochalcone A(2),3′,5′-diisopentenyl-2′,4′-dihydroxychalcone(3),candidachalcone(4),O-methylpongamol(5),(+)-tephrosone(6),spinochalcone C(7),epoxyobovatachalcone(8),tunicatachalcone(9),crassichalone(10)and(S)-elatadihydrochalcone(11).【Conclusion】All the compounds mentioned above belong to chalcones,which are isolated fromT.purpureafor the first time.
