    • Abstract


      Kanugin C19H16O7 yields myristicic acid andp-methoxy salicylic acid when decomposed with aqueous alcoholic potash and myristicic acid ω: 4-dimethoxy-2-hydroxy-acetophenone when decomposed with absolute alcoholic potash. Nor-kanugin has been identified as robinetin by a comparison of the flavonols and their derivatives. It is, therefore, concluded that kanugin is 3∶7∶5′-trimethoxy-3′∶4′-methylenedioxy-flavone. The crystalline components of the seeds, flowers and root bark ofPongamia glabra are compared.
