【摘要】 应用色谱技术,从红树植物海漆Excoecaria agallocha L.中获得11种酚苷类化合物。其中,化合物1为新的酚苷类化合物,命名为1-(3,5-dimethoxy-4-hydroxybenzyl)-6-O-galloyl-1-O-β-D-glucopyranoside(1)。已知糖苷分别鉴定为3,5-dimethoxy-4-hydroxybenzyl-1-O-β-D-glucopyranoside(2),hydrangeifolin I(3),(2-methoxy-5-hydroxymethyl-phenyl)-1-O-β-D-(6-O-galloyl)glucopyranoside(4),(3,5-dimethoxy-4-hydroxyphenyl)-1-O-β-D-(6-O-galloyl)glucopyranoside(5),3-methoxy-4-hydroxyphenyl 1-O-β-D-(6-O-galloyl)glucopyranoside(6),3,4,5-trimethoxyphenyl-(6-O-galloyl)-1-O-β-D-glucopyranoside(7),koaburaside(8),koaburaside monomethyl ether(9),cuneatasides D(10),(E)-isosyringin(11)。化合物2-6,8-11为首次从大戟科海漆属中分得。新化合物的结构经理化性质及1D,2D NMR方法确定,已知化合物的结构通过波谱分析及与文献数据比较得以确定。更多还原

【Abstract】 Chemical examination of a Chinese mangrove plant Excoecaria agallocha L.led to the isolations of a new glucoside named l-(3,5-dimethoxy-4-hydroxybenzyl)-6-O-galloyl-l-O-β-D-glucopyranoside(1),together with 10 known glycosides including 3,5-dimethoxy-4-hydroxybenzyl-l-O-β-D-glucopyranoside(2),hydrangeifolin I(3),(2-methoxy-5-hydroxymethyl-phenyl) -l-O-β-D-(6-Ogalloyl) glucopyranoside(4),(3,5-dimethoxy-4-hydroxyphenyl)-l-O-β-D-(6-O-galloyl) glucopyranoside (5),3-methoxy-4-hydroxyphenyl l-O-β-D-(6-O-galloyl) glucopyranoside(6),3,4,5-trimethoxyphenyl-(6-O-galloyl)-O-β-D-glucopyranoside (7),koaburaside(8),koaburaside monomethyl ether(9),cuneatasides D(10),and(?)-isosyringin(11).Their structures were determined through the extensive spectroscopic analysis and comparison with the reported data in literature. Compounds 2-6,8-11 were isolated from the genus Excoecaria for the first time.更多还原
