| 中文摘要: |
| 山土瓜( Ipomoea hungαiensis Lingelsh. et Borza) 根茎用甲醇提取， 利用硅胶柱层
析、Sephadex LH - 20 柱层析和反相柱层析进行化学成分分离纯化， 从中分离得到7 个化合物.
根据现代波谱技术和理化性质对化合物结构进行鉴定，鉴定结构为: 3β - friedlinol (1) 、lupeol
3 - (3 R - hydroxy) - octadecanoate (2) 、6 ,7 - dihydroxycoumarin (3) 、octadecyl caffeate (4) 、
syringic acid (5) 、β - sitosterol -β- D - glucopyranoside (6) 和β - 谷笛醇(7) .其中化合物
(2) 、(5) 为首次从该植物中分离得到. |
| 英文摘要: |
| Seven compounds were obtained by silica gel chromatography , SephadexLH - 20 chromatography and reversed phase
chromatography from the methanol extract of the root of Ipomoea hungαl iens is Lingelsh. et Borza in Yunnan. TIe
chemical structures of these compounds were identified by modern spectroscopic analysis combined with their physico chemical
data. These compounds were identified to be 3β， - friedlinol (1) , lupeol 3 - (3 R - hydroxy) - octadecanoate
(2) , 6 ,7 - dihydroxycoumarin (3) , octadecyl caffeate (4) , syringic acid (5) ， β - sitosterol -β- D - glucopyranoside
(6) and β- sitosterol (7). Among them, compounds 2 and 5 were isolated from I. hungaiensis for the first time. |
