description

Two new benzopyran derivatives, (6E,10E)-isopolycerasoidol and polycerasoidin methyl ester, have been isolated from a methanolic extract of the stem bark of Polyalthia cerasoides. Their structures were established on the basis of chemical and spectral evidence. Polyalthia sclerophylla contains (6E,10E)-isopolycerasoidol, besides the known polycerasoidin and polycerasoidol. In addition, a known phenylpropene derivative, trans-asarone, has also been isolated from both species and fully characterized.
