摘要：

The twigs of Dorstenia poinsettifolactone yielded poinsettifolactone, a new dihydro-4-phenylcoumarin, and dorspoinsettifolin, a new 7,8-(2,2-dimethylpyrano)-4'-methoxyflavanone. Three known prenylated flavonoids, 4-hydroxylonchocarpin, 4-methoxylonchocarpin and 4'-hydroxyisolonchocarpin, were also isolated and identified. Structures were established by spectroscopic analysis and chemical correlations. (C) 1999 Elsevier Science Ltd. All rights reserved.
