Abstract
Two new furano-flavones (compounds C and D) were reported by Row1 from the root bark of Pongamia pinnata (L.) Merr., besides karanjin (I) and its methylene dioxy derivative, named pongapin. From a study of the alkaline degradation and other reactions, they were regarded as isomeric with pongapin and karanjin respectively.
