简介:目的:研究版纳藤黄Garciniaxipshuanbannaensis果实的化学成分.方法:利用硅胶柱色谱和SephadexLH-20柱色谱分离版纳藤黄果实的化学成分,通过波谱技术鉴定化舍物的结构。结果:从该植物果实的乙醇提取物中分离并鉴定了12个化合物,其结构分别为tovophyllinB(Ⅰ),β-谷甾醇(Ⅱ),熊果酸(Ⅲ),1-十八醇(Ⅳ),isogarcinol(Ⅴ),3’,5,7-三羟基-4’-甲氧基黄酮(Ⅵ),木犀草素(Ⅶ),luteolin-7—O-glucuroaicacidmethylester(Ⅷ),胡萝卜亭(Ⅸ),牡荆苷(Ⅹ),β-D-吡喃阿拉伯糖(Ⅺ),蔗糖(Ⅻ)。结论:化合物Ⅰ、Ⅲ~Ⅺ为首次从该种植物中得到.
简介:目的:研究刺蒺藜果实中的呋喃皂苷。方法:以硅胶柱层析,反相硅胶柱层析及制备液相分离化合物,根据理化性质,波谱数据及化学反应鉴定结构。结果:分离得到两个皂苷,分别为3-O-{β-D-xylopyranosyl(1→3)-[β-D-xylopyranosyl(1→2)]-β-D-glucopyranosyl(1→4)-[α-L-rhamnopyranosyl(1→2)]-β-D-galactopyranosy}-26-O-β-D-glucopyranosyl-5α-furost-12-one-22-methoxyl-3β,26-diol(terrestrosideA)和3-O-{β-D-xylopyranosyl(1→3)-[β-D-xylopyranosyl(1→2)]-β-D-glucopyranosyl(1→4)-[α-L-rhamnopyranosyl(1→2)]-β-D-galactopyranosy}-26-O-β-D-glucopyranosyl-5α-furost-22-methoxyl-3β,26-diol.结论:TerrestrosideA为新化合物。
