Abstract

The seeds of Psolalea corylifolia were extracted with ether and 60% EtOH, successively. The latter extract was found to contain the known constituents psoralen, angelicin, corylifolinin, bukuchiol, p-hydroxybenzoic acid, and astragalin, together with two new benzofuran derivatives, corylifonol and isocorylifonol. Their structures have been elucidated by spectral evidence and chemical transformation.
