Özet

Two new phenylpropanoid glucosides, 1,2-erythro-1-(3,4,5-trimethoxyphenyl)-2-(beta-D-glucopyranosyloxy)propan-1,3-diol (1) and 7,8-threo-2',8-epoxysyringylglycerol-7-O-alpha-D-glucopyranoside (ericarboside; 2) have been isolated together with four known compounds 2',7-epoxysyringylglycerol-8-O-beta-D-glucopyranoside (ficuscarpanoside B; 3), benzylrutinoside (hydrangeifolin; 4), phenethylrutinoside (5), and caffeic acid from the BuOH soluble part of the MeOH extract of the leaves and flowers of E. arborea L. Final purification of the compounds was achieved on a reversed-phase HPLC. Their structures have been elucidated by extensive 1D- and 2D-NMR, and mass spectroscopic techniques.
