【摘要】 从国产番麻叶中分离出八种甾族皂甙元,为替告皂甙元(Tigogenin)、海柯皂甙元(Hecogenin)、9-去氢海柯皂甙元(9-Dehydrohecogenin)、洛柯皂甙元(Rockogenin)、12-表洛柯皂甙元(12-Epjrockogenin)、芰脱皂甙元(Gitogenin)、绿莲皂甙元(Chlorogenin)和曼诺皂甙元(Manogenin)。12-表洛柯皂甙元首次由植物分离得到。除海柯皂甙元以外,其他七种甙元均与部分合成的对照样品核对,还对芰脱皂甙元以外的其他七种甙元的核磁共振谱作了分析和讨论。更多还原

【Abstract】 Tigogenin, hecogenin, 9-dehydrohecogenin, rockogenin, 12-epirockogenin, gitogenin, chlorogenin and manogenin were isolated from leaves of Agave americana L. gathered from Kwangtung Province. Although 12-epirockogenin has been reported in the literature as the reduction product of hecogenin, yet it is the first time ever isolated directly from a plant. The NMR spectra of these sapogenins with the exception of gitogenin were also reported and discussed.更多还原
