Pongarotene (1), a new rotenoid and karanjin (2), a known flavonol, were isolated from the seeds of Pongamia pinnata. The structure determination of these compounds were based on spectral analyses including 2D-NMR. The antifungal, antibacterial and phytotoxicity results of pure compounds 1 and 2 as well as of the methanol (M) and ethyl acetate (E) crude extracts are also being reported.
