药用红树林植物黄槿的化学成分研究

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...
