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.
