Abstract
Four new styryllactones, leiocarpin A (1), 7-epi-goniodiol (2), leiocarpin B (3) and leiocarpin C (4), respectively, were isolated from the stem bark of Goniothalamus leiocarpus. Their structures were elucidated by means of s pectral method. The relative configurations of 1, 2 and 3 were determined b y X-Ray crystallographic analysis. Compounds 2 and 3 possess antitumor acti vities.
