Abstract


Three megastigmanes, bridelionoside B (1), (3S,5R,6R,7E,9S)-megastigmane-7-ene-3,5,6,9-tetrol (2), and dihydroalangionoside A (3), and one phenylpropane glucoside, syringin (4) were isolated from the methanol extract of Ficus microcarpa leaves. Their structures were elucidated by spectroscopic methods including ESI-MS, 1D- and 2D-NMR in comparison with the literature values.

Keywords: Ficus microcarpa, Moraceae, megastigmane.
