摘  要:目的:研究肾茶(Clerodendranthus spicatus)地上部位的水溶性成分。方法:应用大孔吸附树脂层析,硅胶柱层析。反相柱层析和Sephadex LH-20柱层析等多种方法进行分离纯化,通过波谱解析和理化鉴别进行结构鉴定。结果:分离得到7个化合物,分别为:咖啡酸(caffeic acid,1)、迷迭香酸(rosmarinic acid,2)、迷迭香酸甲酯(methyl rosmarinate,3)、紫草酸单甲酯(methyl lithospermate,4)、紫草酸二甲酯(dimethyl lithospermate,5)、特草酸乙单甲酯(methyl lithospermate B,6)、紫草酸乙二甲酯(dimethyl lithospermate B,7)。结论:化合物3—7均为首次从该植物中分得。AIM: To study the water-soluble constituents of the aerial paris of Clerodendranthus spicatus. METHOD: The water soluble fractions were subjected to a series of chromatographic separation methods to afford six caffeic acid depsides, as well as free caffeic acid. Their structures were elucidated mainly by spectroscopic methods. RESULT: Seven compounds: caffeic acid (1), rosmarinic acid (2), methyl rosmarinate (3), methyl lithospermate (4) and dimethyl lithospermate (5), methyl lithospermate B (6), dimethyl lithospermate B (7) have been isolated from Clerodendranthus spicatus. CONCLUSION: Compounds 3 - 7 have been isolated from this plant for the first time.
