Three stilbenoid compounds, hopeaphenol (1), laevifonol (2), dan (+)-α-viniferin (3) had been isolated from acetone extract of the stem bark of Shorea leprosula Miq. The molecular structures of (1), (2), and (3) was determined based on spectroscopic data, including UV, IR, 1H NMR, and 13C NMR, and comparison with that reported in the literature.
