| Abstract: | Twelve compounds were isolated from Micromelum falcatum and purified by repeated column chromatography on silica,Sephadex LH-20 gel,and HPLC and structurally identified by spectral analysis.The compounds were identified as 5-formyl-6,7-dimethoxycoumarin(1),isoscoploletin-β-D-glucoside(2),6-(trans-1-buten-3-only)-7-methoxycoumarin(3),isoscopoletin-(6-hydroxyl-7-methoxyl coumarin,isoscopoletin)(4),microfalcatin isovalerate(5),micromelin(6),syringin(7),coniferin(8),Methyl 2-O-β-D-glucopyranosylbenzoate(9),2-hydroxy-5-methoxy-trans-cinnamic acid(10),3,5-dimethoxyl-4-hydroxyl benzaldehyde(11) and o-sec-butyl phenol(12).Compound 1 previously synthesized but first isolated as natural product,and the other compounds were isolated from this plant for the first time except 5 and 6. |
