Beberapa Oligomer Stilbenoid dari Tumbuhan Shorea multiflora Burck

Abstract
Two dimers of stilbenoids, (-)-balanocarpol (4), and (-)-ampelopsin A (5), along with a tetramer (-)-hopeaphenol (6) were isolated from the stem bark of Shorea multiflora Burck (Dipterocarpaceae), locally known as Meranti. Their structures were determined by physical and UV, IR, 1H-NMR, and 13C-NMR spectroscopic data.
Keyword : (-)-ampelopsin A, (-)-balanocarpol, Dipterocarpaceae, (-)-hopeaphenol, Meranti, Shorea multiflora Burck.
