Two new prenylflavanones, tanariflavanones A (1), and B (2), and one known compound, (-)-nymphaeol-C (3), were isolated from the fallen leaves of Macaranga tanarius. Compounds 1 and 2 showed inhibition of radical growth of lettuce seedlings at 200 ppm. Their structures were elucidated primarily by NMR, circular dichroism, and mass spectroscopic methods.
