异柱五加叶中齐墩果烷型皂苷的研究

摘要

Four known oleanane glycosides were isolated for the first time from the MeOH extract of the leaves of Acanthopanax sieboldianus forma albeofolium Yook by using column chromatography.They were identified as kalopanax-saponin B (1),acanthopanax saponin CP3 (2),kalopanax-saponin A (3) and sieboldianoside A (4) on the basis of physicochemical and spectroscopic data (1H NMR,13C NMR,2D NMR and FAB-MS).%利用柱色谱从异柱五加 (Acanthopanax sieboldianus forma albeofolium Yook) 叶的甲醇提取液中分离出四个齐墩果烷型皂苷类化合物.通过波谱方法(1H NMR、13C NMR、2D NMR和FAB-MS)鉴定它们分别为kalopanax-saponin B (1)、acanthopanax saponin CP3(2)、kalopanax-saponin A (3) 和sieboldianoside A (4).
