【摘要】 用硅胶柱层析和凝胶柱层析对红树林植物海漆(Excoecaria agallochaL.)的乙酸乙酯提取物进行分离纯化,从中分离得到9个化合物;通过波谱学数据它们分别鉴定为kayadiol(1)、8(14),15-isopimaradiene-7α,18-diol(2)5、,11-epoxy-9-hydroxy-7-megastigmen-3-one(3)、annuionone E(4)、28,30-dihydroxy-lup-20(29)-ene-3-one(5)、mes-sagenic acid G(6)、3,β24-dihydroxy-12-oleanen-28-oic acid(7)s、yringaresinol(8)、ethyl gallate(9)。这些化合物均为首次从该植物中分离得到。更多还原

【Abstract】 Nine compounds were isolated from the EtOAc extract of the leaves of Excoecaria agallocha L.by gel and silica gel column chromatography.On the basis of spectral data,they were identified as kayadiol(1),8(14),15-isopimaradiene-7α,18-diol(2),5,11-epoxy-9-hydroxy-7-megastigmen-3-one(3),annuionone E(4),28,30-dihydroxy-lup-20(29)-ene-3-one(5),messagenic acid G(6),3β,24dihydroxy-12-oleanen-28-oic acid(7),syringaresinol(8),and ethyl gallate(9).All the compounds were isolated from the plant for the first time.更多还原
