Four oligoresveratrols ranging from dimer to tetramer, isolated from stem bark of Hopea mengarawan (Dipterocarpaceae) plants were tested for their activity as hydroxyl radical scavenger. The activity of these compounds was evaluated against the 2-deoxyribose degradation induced nu the hydroxyl radical generated via a Fenton-type reaction. Result showed that balanocarpol, heimiol A, vaticanol G. and vaticanol B had IC (50) 3.83 ; 15.44 ; 2.01 ; 4.71 uM, respectyively. These results suggest that oligoresveratrols from stem bark og H. mengarawan maybe useful as potential sources of natural antioxidants.
