摘要 目的:研究白射干根茎的化学成分。方法:采用各种柱色谱法分离,通过理化鉴别及波谱分析技术鉴定化合物的结构。结果:从白射干根茎中分离得到了11个化合物,分别鉴定为粗毛豚草素(hispidulin,1),鼠李柠檬素素(rhamnocitrin,2),鸢尾甲黄素A(iristectorigenin A,3),4′,5,7,8-四羟基-6-甲氧基异黄酮(4′,5,7,8-tetrahydroxy-6-methoxy isoflavone,4),6-羟基鹰嘴豆素A(6-hydroxybiochanin A,5),鸢尾甲苷B(Iristectorin B,6),鸢尾甲黄素A(Iristectorigenin A,7),山柰酚-7-甲醚(Kaempferol-7-methyl ether,8),怪柳黄素-7-葡萄糖苷(Tamarixetin-7-glucoside,9),鸢尾甲苷A(Iristectorin A,10),3′,3,5-三羟基-4′,7-二甲氧基黄酮-3-O-β-D-半乳糖苷(3′,3,5-trihydroxy-4′,7-dimethoxy-flavone-3-O-β-D-galacto pyranoside,11)。结论:化合物1~11均是首次从该植物中分离得到。 Objective: To study the chemical constituents in the rhizoma of Iris dichotoma.Method: The chemical constituents were isolated by various column chromatographic methods.The structures of the compounds were elucidated on the basis of physiochemical properties and spectral analysis.Result: Eleven compounds,hispidulin(1),rhamnocitrin(2),iristectorigenin A(3),4′,5,7,8-tetrahydroxy-6-methoxy isoflavone(4),6-hydroxybiochanin A(5),iristectorin B(6),iristectorigenin A(7),kaempferol-7-methyl ether(8),tamarixetin-7-glucoside(9),iristectorin A(10),3′,3,5-trihydroxy-4′,7-dimethoxy-flavone-3-O-β-D-galactopyranoside(11) were isolated and identified.Conclusion: Compounds 1-11 were obtained from this plant for the first time.
