| 中文摘要 |
本研究由大葉刺桐 （Erythrina arborescens Roxb.） 莖皮部分離得到八個成分，經光譜分析確定其結構分別為squalene （1）, phytosterols （2）, oleanolic acid （3）, alpinumisoflavone （4）, erythrivaroneC （5）, warangalone （6）, erythrinin C （7） 及phytosteroid glycosides （8） 。From the methanolic extracts of stem bark of Erythrina arborescens Roxb. (Leguminosae) eight components were obtained. The structure of these compounds were elucidated as squalene (1), phytosterols (2), oleanolic acid (3),alpinumisoflavone (4), erythrivarone C (5), warangalone (6), erythrinin C (7) and a mixture of phytosteroid glycosides (8) by the usual spectroscopic methods and 2D NMR techniques. |
