Abstract
The bark of Ekebergia pterophylla yielded atraric acid, beta-amyrin, beta-amyrone, oleanonic acid, beta-sitosterol, beta-sitosteryl acetate and the novel coumarins, pterophyllins 1 and 2. Extractives of the wood yielded the novel coumarins, pterophyllins 3-5. Lupeol was isolated from the hexane extract of the leaves. (C) 1998 Elsevier Science Ltd. All rights reserved.
