【摘要】 云南巴豆（Croton yunnanensis）枝叶风干粉碎后用甲醇提取，使用硅胶柱层析、MCI柱层析、Sephadex LH-20凝胶柱层析及HPLC等分离技术对其化学成分进行分离纯化，得到5个倍半萜类化合物，分别是（-）-ent-6α-methoxyeudesm-4(15)-en-1β-ol (1), oplodiol (2),(7R~*)-opposit-4(15)-ene-1β,7-diol (3), aphanamol I (4)和orientalol C (5)。化合物11-4为首次从该种植物中分离得到。更多还原

【Abstract】 The branches and leaves of Croton yunnanensis were dried and extracted with methanol. The chemical components were separated and purified by silica gel column chromatography, MCI column chromatography, Sephadex LH-20 gel column chromatography and HPLC. These compounds were identified as(-)-ent-6α-methoxyeudesm-4(15)-en-1β-ol(1),oplodiol(2),(7R~*)-opposit-4(15)-ene-1β,7-diol(3), aphanamol I(4) and orientalol C(5). Compounds 1-4 were isolated from this plant for the first time.更多还原
