中文摘要: |
塞内加尔刺桐( Erythrina senegalensis )枝叶以甲醇提取,用硅胶柱层析和Sephadex LH-
20凝胶柱层析进行化学成分分离纯化,得到5个生物碱,经核磁共振波谱和理化性质分析对化合物
结构进行鉴定,鉴定它们的结构为 erytharbine(1 1)、(+)-erysotramidine(2 2)、erysotrine(3 3)、
erysotrine- N -oxide(4 4)、 (+)-11 α -hydroxyerysotrine(5 5)。均为首次从塞内加尔刺桐中分离得到。 |
英文摘要: |
Five alkaloids were isolated from Erythrina senegalensis by silica gel chromatography and Sephadex LH-20
chromatography. Their structures were identified as erytharbine (1), (+)-erysotramidine (2), erysotrine (3), erysotrine-N-ox⁃
ide (4) and (+)-11α-hydroxyerysotrine (5) by the analysis of NMR spectroscopic data combined with their physicochemical
data. All the alkaloids were isolated from Erythrina senegalensis for the first time. |
