Article abstract of DOI:10.1016/S0031-9422(97)01117-5

Two new tri-O-glycoside flavonols: kaempferol and quercetin 3-O-α- rhamnopyranosyl(1 → 6)-βglucopyranosyl(1 → 6)-β-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.
