    Author: Yuan K, Lü JL, Yin MW.
    Journal: Yao Xue Xue Bao; 2006 May; 41(5):435-8. PubMed ID: 16848320.
    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.
