摘要
目的 研究东亚绢藓 Entodon okamurae的化学成分。方法 用硅胶柱色谱、凝胶柱色谱及制备 TL C对东亚绢藓的乙醇提取物进行分离纯化 ,通过 1 HNMR、1 3CNMR、DEPT、IR、MS等波谱学方法对其分离产物进行结构鉴定。结果 分离得到了 9个化合物 ,分别确定为 :大黄酚 (chrysopham ol, )、大黄素甲醚 (physcion, )、二十九烷 - 10 -醇 (nonacosam n- 10 - ol, )、dryocrassol( )、邻苯二甲酸异丁酯 (phthalic acid isodibutyl ester, )、正十六烷醇 (n- hexadecanol, )、莪术醇 (curcumol, )、β-谷甾醇 (β- sitosterol, )和β-胡萝卜苷 (β- daucsosterol, )。结论 上述化合物均系首次从该属植物中得到 ;除 β-谷甾醇和 β-胡萝卜苷外 。
Object To study the chemical constituents of Entodon okamurae Broth Methods The ethanol extract of E okamurae was isolated by silica gel column chromatograpy and Sephadex LH 20, and purified by preparative TLC; nine compounds were identified by 1HNMR, 13 CNMR, DEPT, IR and MS spectral data Results Their structures were elucidated as chrysophamol (Ⅰ), physcion (Ⅱ), nonacosamn 10 ol (Ⅲ), dryocrassol (Ⅳ), phthalic acid isodibutyl ester (Ⅴ), n hexadecanol (Ⅵ), curcumol (Ⅶ), β sitosterol (Ⅷ) and β daucsosterol (Ⅸ) Conclusion All the compounds are first isolated from Entodon C. Müll. and except β sitosterol and β daucesosterol, others from the plants of Liveworts and Mosses for the first time
