Abstract
Objective To investigate the chemical components from the branches and leaves of Tephrosia purpurea. Methods The isolation of chemical components were carried out by column chromatographies on silica gel and Sephadex LH-20. Their structures were identified on the basis of NMR and MS analysis, and by comparison of their spectroscopic data with those reported in the literature. Results Twelve compounds were obtained from the branches and leaves of Tephrosia purpurea and characterized as: pumilanol ( 1 ) , tephrocandidin A ( 2 ) , tephrospiroketone I ( 3 ) , 1β-hydroxy-6, 7α-dihydroxyeudesm-4 ( 15 )-ene ( 4 ) , calophione A ( 5) , (+)-lariciresinol-9′-stearate ( 6) , tephroapollin D ( 7) , cineroside A ( 8) , hookerianin ( 9) , ( 2S)-5-hydroxy-7, 4′-di-O-(γ, γ-dimethylallyl) flavanone ( 10) , tephrospirolactone ( 11) , candirone ( 12) . Conclusion All the compounds mentioned above were isolated from T. purpurea for the first time.关键词
