利用正相硅胶柱色谱、反相硅胶柱色谱、凝胶Sephadex LH-20柱色谱、制备薄层色谱(PTLC)及重结晶等分离手段,从海洋红树林植物黄槿(Hibiscus tilisceus)中分离得到11个化合物,通过MS、1D和2D NMR等波谱技术鉴定了所有化合物的结构,分别为coniferaldehyde(1),3,4-二羟基苯甲酸甲酯(2),松脂醇(3),丁香脂素(4),格榄酮(5),黄芪苷(6),植醇(7),胆甾-5-烯-3β,7α-二醇(8),胆甾-5-烯-3β,7β-二醇(9),胆甾醇(10)和声-胡萝卜苷(11)。这些化合物均为首次从该植物中分离获得。
From the medicinal mangrove plant Hibiscus tilisceus, eleven compounds were isolated by the normal phase silica gel, reverse phase silica gel, Sephadex LH-20 column chromatography separation, and by the preparative thin layer chromatography (PTLC) as well as by re-crystallization. The structures of the purified compounds were elucidated by the analysis of spectroscopic data including MS, 1D and 2D NMR as coniferaldehyde (1), methyl 3,4-dihydroxybonate (2), pinoresinol (3), syringaresinol (4), gramrione (5), astragalin (6), phytol (7), cholest-5-ene-3β,7α-diol (8), cholest-5-ene-3β, 7β-diol (9), cholesterol (10), and β-daucosterol (11) These compounds were obtained from this plant for the first time.
