半红树植物黄槿中的三萜和甾醇成分(英文)

Triterpenes and Steroids from Semi-mangrove Plant Hibiscus tiliaceus

目的:研究半红树植物黄槿(Hibiscus tiliaceus L.)的化学成分。方法:分离纯化采用硅胶色谱、Sephadex LH-20凝胶色谱、高效液相色谱等方法。结构鉴定通过理化常数和波谱数据与文献对照确定。结果:从黄槿中共分离鉴定了10个化合物,分别为:木栓酮(1)、粉蕊黄杨二醇(2)、β-粘霉烯醇(3)、羽扇豆醇(4)、日耳曼醇(5)、豆甾-4-烯-3-酮(6)、豆甾-4,22-二烯-3-酮(7)、麦角甾-4,6,8(14),22-四烯-3-酮(8)、β-谷甾醇(9)和豆甾醇(10)。结论:化合物3～5和8为首次从该植物中分离得到。

AIM： To study the chemical constituents of semi-mangrove plant Hibiscus tiliaceus. METHODS： The isolation and purification of compounds were performed by silica gel, Sephadex LH-20 and HPLC, and their structures were determined by comparison of their physical and spectral data with the literatures. RESULTS： Ten compounds were isolated and identified as friedelin （1）, pachysandiol （2）, glutinol （3）, lupeol （4）, germanicol （5）, stigmast-4-en-3-one （6）, stigmast-4, 22-dien-3-one （7）, ergosta-4, 6, 8 （14）, 22-tetraen-3-one （8）, β-sitosterol （9）, and stigmasterol （10）. CONCLUSION： Compounds 3-5 and 8 were isolated from this plant for the first time.
