title: A new biflavonyloxymethane from Pongamia pinnata.
abstract: The root bark of Pongamia pinnata Pierre Syn Pongamia glabra (Family: Fabaceae) has afforded a new biflavonyloxymethane, karanjabiflavone, along with a known furanoflavone, pongapin. The structure of this new biflavonyloxymethane was elucidated from extensive spectral studies including 2D-NMR experiments. Both of these compounds possess antioxidant activity.
