五叶地锦化学成分研究

Chemical constituents from Parthenocissus quinquefolia

目的：研究五叶地锦Parthenocissus quinquefolia茎的化学成分。方法：采用薄层色谱,硅胶柱色谱,Sephadex LH-20凝胶柱色谱等方法进行分离纯化,使用波谱分析技术和理化常数对照等方法对得到的化合物进行结构鉴定。结果：从五叶地锦的醋酸乙酯部位分离得到9个化合物,分别为没食子酸（3,4,5-trihydroxy-benzoic acid1）,piceatannol（2）,白藜芦醇（res-veratrol3）,resveratrol trans-dehydrodimer（4）,cyphostemmin B（5）,pallidol（6）,cyphostemmin A（7）,槲皮素3-O-α-L-鼠李糖苷（quercetin-3-O-α-L-rhamnoside8）,myricetin-3-O-α-L-rhamnoside（9）。结论：化合物1,4~9均为首次从该植物中分离得到。

The chemical constituents of Parthenocissus quinque were investigated.The chemical constituents were isolated by column chromatography on silical gel and sephadex LH-20.Their structures were elucidated on the basis of spectral analysis and of comparison of physical constant.Nine compounds were isolated from this plant and the structures of them were identified as 3,4,5-trihydroxy-benzoic acid（1）,piceatannol（2）,resveratrol（3）,resveratrol trans-dehydrodimer（4）,cyphoste mmin B（5）,pallidol（6）,cyphostemmin A（7）,quercetin-3-O-α-L-rhamnoside（8）,myricetin-3-O-α-L-rhamnoside（9）,respectively.Compounds 1,4-9 were isolated from this plant for the first time.
