Abstract

Three resveratrol oligomers have been isolated from the stem bark of H. gregaria including a resveratrol trimer i.e. α-viniferin (1), and two resveratrol tetramers i.e. vaticanol B (2) and hopeaphenol (3). These structures were determined by spectroscopic evidence including UV, IR, 1H , 13C NMR and compared with that of the reported data in the literatures. Activities of the compounds were determined toward brine shrimp Artemia salina (toxicity) and murine leukemia P-388 cells (cytotoxicity). The compound 1 is the most active against A. salina (LC50 = 49,0 ± 5,8 μg/mL), and the compound 3 has very active level toward murine leukemia P-388 cells (LC50 = 5,7 ± 0,3 μM).Key words : Resveratrol oligomers, H. gregaria, toxicity, and cytotoxicity.

Abstract

Nine resveratrol oligomers have been isolated from the stem bark of Hopea mengarawan i.e. diptoindonesin D (1), balanocarpol (2), ampelopsin A (3), hopeaphuran (4), heimiol A (5), parviflorol (6), a-viniferin (7), isohopeaphenol (8), and vaticanol B (9).The structures of these compounds were determined based on spectroscopic evidence such as UV, IR, 1-D, 2-D NMR and comparison with the reported data. Those compounds implied that Hopea tends to produce resveratrol dimers. Moreover, in subgenus level, besides ampelopsin A (3) and isohopeaphenol (9), resveratrol oligomers in H. mengarawan the same as in H.dryobalanoides. It indicated that H. mengarawan and H. dryobalanoid.es came from the same subgenus.
