太白花化学成分的研究(英文)

Chemical constituents of Cladonia stellaris

目的 研究地衣植物太白花(又称雀石蕊)Cladonia stellaris的化学成分。方法 太白花经石油醚提取,采用硅胶柱色谱和硅胶制备TLC分离纯化,波谱分析鉴定结构。结果 从太白花的石油醚部分得到6个化合物,分别鉴定为:松萝酸(Ⅰ)、去甲环萝酸(Ⅱ)、珠光酸(Ⅲ)、漂红梅衣酸(Ⅳ)、2-羟基-4-甲氧基-6-正戊基苯甲酸(Ⅴ)和2,4-二羟基-6-正戊基苯甲酸(Ⅵ)。结论 化合物Ⅱ和Ⅳ为首次从太白花中分离得到。

Object To study the chemical constituents in lichen plant of Cladonia stellaris. Methods C. stellaris was extracted with petroleum ether, separated and purified by column chromatography and preparative TLC on silica gel. All the compounds were identified on the basis of spectral analysis. Results Six compounds were obtained. Their structures were characterized as usnic acid (Ⅰ) , evinic acid (Ⅱ) , perlatolic acid (Ⅲ) , olivetoric acid (Ⅳ) , 2-hydroxyl-4-methoxyl-6-pentyl benzoic acid (Ⅴ) and 2, 4-dihy- droxyl benzoic acid (Ⅵ), respectively. Conclusion Compounds Ⅱ and Ⅳ were isolated from C. stellaris for the first time.
