  摘要：

  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, H-1 and C-13-NMR spectral analysis. (C) 1998 Elsevier Science Ltd. All rights reserved.
