Chemical constituents of C-glycosylflavones from Mimosa pudica / 药学学报

ABSTRACT

<p><b>AIM</b>To study chemical constituents of Mimosa pudica of Hainan province.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSION</b>Compound I is a new compound and componuds II - IV were isolated from this plant for the first time.</p>
