川射干叶的化学成分研究

摘要

OBJECTIVE:To study the chemical compositions of the leaves of Iris tectorum. METHODS:Using 70% ethanol for extracting,silica gel column chromatography,Sephadex LH-20 chromatography and thin-layer chromatography were used to iso-late and purify the chemical compositions of the leaves of I. tectorum,the compound structures were analyzed and identified accord-ing to the physicochemical properties and spectral data. RESULTS:12 compounds were isolated from the leaves of I. tectorum, namely 5,7,4′-trihydroxy-6-methoxy isoflavone(1),tiliamin-7-O-β-D-glucopyranoside(2),5-hydroxy- 4′,7- dimethoxy-isofla-vone(3),tectoridin(4),tectorigenin(5),iridin(6),dimethyl tectorigenin(7),genistein(8),protocatechuic acid(9),isorham-netin-7-O-β-D- glucoside (10),daucosterol (11),tetradecanoic acid (12). CONCLUSIONS:Compounds 1,2,3 are isolated from the plants of the genus for the first time,and the study has laid the foundation for the quality evaluation of I. tectorum.%目的：研究川射干叶的化学成分。方法：采用70％乙醇提取，硅胶柱层析及Sephadex LH-20色谱、薄层色谱对川射干叶的化学成分进行分离纯化，根据理化性质和波谱数据分析鉴定化合物结构。结果：从川射干叶中分离得到12个化合物，分别为5，7，4′-三羟基-6-甲氧基黄酮（1）、金合欢素-7-O-β-D-葡萄糖苷（2）、5-羟基-4，′7-二甲氧基异黄酮（3）、射干苷（4）、射干苷元（5）、野鸢尾苷（6）、二甲基射干苷元（7）、染料木素（8）、原儿茶酸（9）、异鼠李素-7-O-β-D-葡萄糖苷（10）、胡萝卜苷（11）、十四酸（12）。结论：化合物1、2、3均为首次从该属植物中分离得到，该研究为川射干叶质量评价奠定了一定基础。
