摘要

摘要: 目的研究海南含羞草(Mimosa pudica)的化学成分。方法利用Diaion HP-20，Toyopearl HW-40，MCI-Gel CHP-20，Sephadex LH-20，RP18及硅胶等柱色谱法对海南含羞草成分进行分离纯化，根据理化性质和光谱数据鉴定化合物的结构。结果分离鉴定了4个化合物：7,8,3′,4′-四羟基-6-C-［α-L-鼠李糖-(1→2)］-β-D-葡糖黄酮碳苷(I)，5,7,4′-三羟基-8-C-［α-L-鼠李糖(1→2)］-β-D-葡糖黄酮碳苷(II)，5,7,3′,4′-四羟基-6-C-［α-L-鼠李糖-(1→2)］-β-D-葡糖黄酮碳苷(III)，儿茶素(IV)。结论化合物I为新化合物，化合物II～IV为首次从该植物中分离得到。

Abstract: AimTo study chemical constituents of Mimosa pudica of Hainan province. Methods The constituents were separated and purified by column chromatography with macroporous adsorption resin Diaion HP-20, Sephadex LH-20, Toyopearl HW-40, MCI Gel CHP-20, RP-18 and normal phase silica gel. Their structures were identified on the basis of physical and spectral data. ResultsFour compounds were isolated and identified as: 7,8,3′,4′-tetrahydroxyl-6-C-［α-L-rhamnopyranosyl-(1→2)］-β-D-glucopyranosyl flavone (I); 5,7,4′-trihydroxyl-8-C-［α-L-rhamnopyranosyl-(1→2)］-β-D-glucopyranosyl flavone (II); 5,7,3′,4′-tetrahydroxyl-6-C-［α-L-rhamnopyranosyl-(1→2)］-β-D-glucopyranosyl flavone (III); catcher (IV). ConclusionCompound I is a new compound and componuds II-IV were isolated from this plant for the first time.
