灰毛豆叶片的化学成分研究

Chemical Constituents from the Leaves of Tephrosia purpurea

从灰毛豆叶片中分离得到10个化合物,通过波谱数据和理化性质分别鉴定为:stigmast-1,5-dien-3β-ol(1),clemaphenol A(2),松脂醇(3),桉素(4),3-吲哚甲醛(5),色氨酸(6),(S)-4-苄基-2-噁唑烷酮(7),4-羟基苯基丙酸(8),buteaspermanol(9),bovatachalcone(10)。其中化合物1、2、4、5、7、8、9首次从该植物中分离得到。

Ten compounds were isolated from the MeOH extracts o~ the Tephrosia purpurea leaves. The structures o~ the compounds were determined on the basis of spoctmscopic data and physicochemical properties. Their structures were elu- cidated as stigmast-1,5-dien-3β-ol （1） ,elemaphenol A （2）, （ ＋ ）-pinoresinol （3） ,eudesmin （4） ,indole-3-carhal.de- hyde （5）,tryptophan （6）, （S）-4-benzyl-2-oxazoHdinone （7）,4-hydroxybenzene pmpanoic acid （8）,buteaspermanol （9）, bovatachalcone （10）. Compounds 1,2,4,5 ,7,8,9 were isolated from the rifle plant for the first time.
