红葱化学成分研究

Studies on Chemical Constituents of Eleutherine americana

目的:对红葱Eleutherine americana Merr.et K. Heyne的化学成分进行研究。方法:采用硅胶柱层析分离纯化化合物,通过MS、NMR等波谱技术确定化合物结构。结果:从红葱中分离得到9个化合物,分别鉴定为:异红葱甲素(1)、红葱乙素(2)、异红葱乙素(3)、β-谷甾醇(4)、8-羟基-3,4-二甲氧基-1-甲基-蒽醌-2-羧酸甲酯(5)、Hongconin(6)、4,8-二羟基-3-甲氧基-1-甲基蒽醌-2-羧酸甲酯(7)、Eleutherinone(8)、Kadsuric acid(9)。结论:其中化合物9为首次从该植物中分离得到。

Objective: To research the chemical constituents from Eleutherine americana.Methods: Column chromatography with silica gel was employed to isolate and purify the constituents.Their structures were elucidated by means of MS and NMR.Results: Eight constituents were obtained and identified as Isoeleutherol(1),eleutherin(2),isoeleutherin(3),β-sitosterol(4),8-hydroxy-3,4-Dimethoxy-1-methyl-anthra-9,10-quinone-2-carboxylic acid methyl ester(5),Hongconin(6),4,8-Dihydroxy-3-Methoxy-1-methyl-anthra-9,10-quinone-2-carboxylic acid methyl ester(7),Eleutherinone(8),Kadsuric acid(9).Conclusion: Compound 9 is isolated from the plant for the first time.
