[Chemical constituents of C-glycosylflavones from Mimosa pudica].
OBJECTIVE
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).


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