| Résumé | One new triterpene glycoside 3-O-beta-D-xylopyranosyl-(1 -> 4)-[beta-D-glucopyranosyl-(1 -> 3)]-beta-D-xyl opyranosyl-(1 -> 4)-beta-D-xylopyranosyl-(1 -> 3)-alpha-L-rhamnopyranosyl-(1 -> 2)-alpha-L-arabinopyranosyloleanolic acid, was isolated from Weigela x ``kosteriana variegata'' (Caprifoliaceae), with three known ones. Their structures were characterized by a combination of mass spectrometry and 1D and 2D NMR spectrocopic techniques including H-1- and C-13 NMR, COSY, TOCSY, NOESY, HSQC, and HMBC experiments. The toxicological properties of some glycosides were determined with a zebrafish-based assay. The results show that the most active compounds were toxic to the larvae in the range of 1 mu M. |
