龙须草化学成分研究

Chemical Constituents of Juncus setchuensis

目的：研究龙须草的化学成分。方法：采用各种柱色谱法分离其成分,运用多种波谱方法鉴定化合物结构。结果：从龙须草的乙酸乙酯部位共分离得到8个化合物,分别鉴定为：2-羟基-3-甲基蒽醌（1）、大黄素甲醚（2）、豆甾醇（3）、豆甾-3,6-二酮（4）、香草醛（5）、正二十七烷酸（6）、反式对羟基桂皮酸（7）、4-羟基-3-甲氧基苯甲酸（8）。结论：其中,化合物1、2、4、6为首次从该属植物中分离得到,化合物1~8均为首次从该植物中分离得到。

Objective： To study the chemical constituents of Juncus setchuensis.Methods： Column chromatography was used in the isolation procedure.The structures of isolated compounds were elucidated by spectral data.Results： Eight compounds were isolated and their structures were identified as 2-hydroxy-3-methylanthraquinone（ 1）,physcion（ 2）,stigmasterol（ 3）,stigmast-3,6-dione（ 4）,vanillin（ 5）,n-heptacosanoic acid（ 6）,trans-hydroxycinnamic（ 7） and 4-hydroxy-3-methoxy benzoic acid（ 8）.Conclusion： Compound 1,2,4 and6 are obtained from this genus for the first time and all the compounds are obtained from this plant for the first time.
