摘要：

Chemical investigation of Kancolla seeds revealed the presence of an array of polyphenols which were dominated by kaempferol and quercetin glycosides. Also isolated was a glucoside of vanillic acid. This is the first report of quercetin 3-O-beta-D-apiofuranosyl-(1"'-->similar to2")-O-[a-L-rhamnopyranosyl-(1"'-->6")]-similar to3-D-galactopyranoside-3',4'-dimethyl ether. All structures were elucidated by chemical and spectroscopic methods, namely NMR (H-1, C-13, COSY, HMQC, HMBC), mass data (FAB-MS, HRFAB-MS, GC-MS), IR and UV. (C) 2003 Elsevier Ltd.
