摘要

目的研究双边栝楼种子中不皂化类脂的化学成分,为制定中药瓜蒌和瓜篓子的质量标准奠定基础。方法乙醚提取脂肪油,氢氧化钾进行皂化反应,对不皂化类脂进行硅胶柱层色谱分离和纯化,用IR,MS,IH-NMR,13C-NMR等光谱技术和对照品对照等方法鉴定化合物的结构。结果鉴定了6个化合物,分别为栝楼仁二醇(I),7.氧代二氢栝楼仁二醇(Ⅱ),lOa-葫芦二烯醇(Ⅲ),豆甾-7-烯-3p-醇(Ⅳ),豆甾-7,22二烯-3p-醇(V)和豆甾-7,22-二烯-3-O-B-D-葡萄糖苷(Ⅵ)。结论前3个化合物系首次从该植物中分离获得。

Abstract

OBJECTIVE To study the chemical constituents of unsaponifiable lipids from the seeds of Trichosanthes rosthornii Harms in order to develop some quality standards for Fructus Trichosanthis and Semen Trichosanthis. METHODS To extract the fatty oil from the seeds of Trichosanthes rosthornii with ether,to carry out the saponification with potassium hydroxide,to isolate and purify the unsaponifiable lipids by using silica gel column chromatography,and to elucidate the stuctures of their constituents by means of IR,MS,1H-NMR,13C-NMR and au-thentic apecimens.RESULTS Karounidiol,7-oxodihydro karounidiol,lOa-cucurbitadienol,stigrnast-7-en-3b-ol,stigmast-7,22-dien-3b-ol and stigmast-7,22-dien-3- O-b-D-glucoside were elucidated. CONCLUSION The preceding three compounds were found in this plant for the first time。
