Abstract
Six new compounds, diospyrolide (1), diospyrolidone (2), diethyl (2R)-malat e (3), 3-(E)-coumaroylbetulin-28-yl ethyl nonanedioate (4), 3-(E)-coumaroyl betulin-28-yl ethyl succinate (5), and 3-(E)-coumaroylbetulin-28-yl ethyl ( 2R)-2-hydroxysuccinate (6), have been isolated from the heartwood of Diospy ros maritima. Compounds 1 and 2 are novel trinorlupanes, and 4, 5 and 6 are lupane derivatives. Their structures were determined using spectral and ch emical methods.
