Two new phenylpropanoid glucosides, 1,2‐ erythro ‐1‐(3,4,5‐trimethoxyphenyl)‐2‐( β‐ D ‐glucopyranosyloxy)propan‐1,3‐diol ( 1 ) and 7,8‐ threo ‐2′,8‐epoxysyringylglycerol‐7 ‐O ‐ α‐ D ‐glucopyranoside (ericarboside; 2 ) have been isolated together with four known compounds 2′,7‐epoxysyringylglycerol‐8 ‐O ‐ β‐ 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.
