摘要：

From the stems of Cyathocalyx crinatus, a rain forest plant in Borneo, six new Diels-Alder adducts, named crinatusins A(1), A(2), B-1, B-2, C-1, and C-2, together with a known chalcone derivative, 4',6'-dihydroxy-3',5'-dimethyl-2'-methoxychalcone have been obtained. Their structures were determined on the basis of spectroscopic data and chemical methods. Crinatusins showed a lethal toxicity against brine shrimp. (C) 2000 Elsevier Science Ltd.
