Abstract

AIM

To 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.

RESULTS

Four compounds were isolated and identified as: 7, 8, 3', 4'-tetrahydroxyl-6-C-[alpha-L-rhamnopyranosyl-(1 --> 2)]-beta-D-glucopyranosyl flavone (I); 5, 7, 4'-trihydroxyl-8-C-[alpha-L-rhamnopyranosyl-( --> 2)]-beta-D-glucopyranosyl flavone (II); 5, 7, 3', 4'-tetrahydroxyl-6-C-[alpha-L-rhamnopyranosyl-(1 --> 2)]-beta-D-glucopyranosyl flavone (III); catcher (IV).

CONCLUSION

Compound I is a new compound and componuds II - IV were isolated from this plant for the first time.

摘要

目的

研究海南含羞草的化学成分。

方法

采用大孔吸附树脂Diaion HP - 20、葡聚糖凝胶Sephadex LH - 20、Toyopearl HW - 40、MCI Gel CHP - 20、RP - 18和正相硅胶柱色谱法对化学成分进行分离纯化，并根据物理和光谱数据鉴定其结构。

结果

分离鉴定出4个化合物，分别为：7, 8, 3', 4'-四羟基-6-C-[α-L-鼠李糖基-(1→2)]-β-D-葡萄糖基黄酮（I）；5, 7, 4'-三羟基-8-C-[α-L-鼠李糖基-(→2)]-β-D-葡萄糖基黄酮（II）；5, 7, 3', 4'-四羟基-6-C-[α-L-鼠李糖基-(1→2)]-β-D-葡萄糖基黄酮（III）；捕蝇草素（IV）。
