Abstract:
Two new tri-O-glycoside flavonols: kaempferol and quercetin 3-O-alpha-rhamnopyranosyl(1-->6)-beta-glucopyranosyl(1-->6)-beta- galactopyranosides, were identified from the leaves of Albizia lebbeck. Structures were established by conventional methods of analysis and confirmed by ESI-MS, 1H and 13C-NMR spectral analysis.
