摘要
目的:研究金叶子(Craibiodendron yunnanese W.W.Smith)的化学成分。方法:利用65%乙醇提取,大孔吸附树脂和硅胶柱色谱等方法进行分离纯化,根据化合物的光谱数据鉴定结构。结果:从金叶子中分离得到7个化合物,分别鉴定为儿茶素(catechin)(1),3,3’,4’,5,6,7,8-heptahydroxyflavan(2),十五碳酸(3),槲皮素(quercetin)(4),乌苏酸(3β-hydroxyurs-12-en-28-oic-acid)(5),棕榈酸(palmitic acid)(6),Benzoicacid,4-[2-(4-methoxyphenoxy)ethyl(]7)。结论:化合物1,2,3,5,7为首次从该种植物分离得到。
Objective： To study the chemical constituents of the leaves of Craibiodendron Yunnanese W. W. Smith. Method： The chemical constituents of Craibiodendron yunnanese W. W. Smith were extracted by 65% ethanolic. Then the chemical constituents were isolated and purified by Diaion and silica gel. Their structures were elucidated on the basis of spectroscopic evidences and physicochemical properties. Result： seven compounds were isolated and identified as catechin （ 1 ）, 3,3＇ , 4＇ , 5,6,7,8 - heptahydroxyflavan （2）, Pentadecanoic acid （3）, quercetin （4）, 313- hydroxyurs- 12- en- 28- oic- acid （5）, palmitic acid （6）, Benzoicacid ,4 - [ 2 - （4 - methoxyphenoxy） ethyl ] （ 7 ）. Conclusion ： Compounds 1,2,3,5,7 were isolated from the leaves of Craibiodendron yunnanese W. W. Smith for the first time.
