Two new prenylated flavanones, 2 S-3'-(2-hydroxy-3-methylbut-3-enyl)licoflavone-4'-methyl ether ( 3) and 2 S-3'-(2-hydroxy-3-methylbut-3-enyl)abyssinone II ( 4), and four known flavanones ( 1, 2, 5, 6) were isolated from the stem bark of Erythrina addisoniae. The structures were elucidated on the basis of their spectroscopic and physicochemical data. None of the compounds showed antioxidative properties. 4'-Methylabyssinone V ( 1) and abyssinoflavanone VII ( 6) showed moderate cytotoxic activity (IC 50 = 5 and 3.5 micromol/L, respectively), but apoptosis (caspase-3/7-activation, nuclear fragmentation) was selectively induced by abyssinoflavanone VII ( 6).
