Phytochemical analysis of the leaves from Chromolaena subscandens afforded ß-sitosterol, umbelliferone, /-methoxybenzoic acid, and several known flavonoids, as well as a new one, 5,7-dihydroxy-8,4'-dimethoxyflavanone, which we have named subscandenin [1]. The structure of this new flavanone was established by spectral methods.
