Two new C-methyl flavanones, named matteucin (III) and methoxymatteucin (IV) were isolated from the root of Matteuccia orientalis TREV. (Aspidiaceae), together with the known desmethoxymatteucinol (I) and matteucinol (II). The structures of these flavanones were determined to be (2S)-5, 7, 2'-trihydroxy-6, 8-dimethylflavanone and (2S)-5, 7, 2'-trihydroxy-5'-methoxy-6, 8-dimethylflavanone, respectively, by spectroscopic evidence.
