摘要
The root bark of Pongamia pinnata Pierre (syn P. glabra Vent.) has afforded a new biflavonyloxymethane, pongabiflavone, along with a known furanoflavone, 3-methoxy-(7, 8, 2 '', 3 '') furanoflavone. The structure of this new compound was elucidated from extensive spectral studies, including 2D-NMR spectroscopic experiments. The antioxidant, radical quenching activity- superoxide and nitric oxide quenching activities of both pongabiflavone and previously isolated karanjabiflavone have been evaluated which can be a key to cure Psoriasis.
