摘要
对产自云南思茅银叶巴豆(Croton cascarilloides)的化学成分进行了研究.利用反复硅胶柱层析、重结晶等分离手段从中分离纯化得到8个化合物,通过现代波谱技术和理化常数测定鉴定了结构,它们是3个二萜,2个芳香类化合物,1个黄酮苷和β-谷甾醇及β-胡萝卜苷.
The chemical constituents of Croton cascarilloides were studied and eight compounds were isolated. The structure of these compounds were elucidated as ent - 8, 9 - 7 α - hydroxy - 11β - acetoxykaura - 8 (14), 16 - dien - 9, 15 - dione( 1 ) ; ent - 8, 9 - seco - 7 α - hydroxykaura - 8 ( 14 ), 16 - dien - 9, 15 - dione (2) ; ent - 8, 9 - seco - 8, 14 - epoxy - 7 α - hydroxy - 11 β- acetoxy - 16 - kauren - 9, 15 - dione(3) ; luteolin - 7 - O - a - L - rhamnoside ( 4 ) ; vanillin (5) ; anisic acid (6) ; β- sitosterol (7) and β- daucosterol (8) by spectral analysis.
