Abstract
From Plumbago indica a new quinone derivative-plumbagic acid lactone, two f lavonol methyl ethers-azaleatin (5-O-methylquercetin), ayanin (3,7,4', tri- O-methylquercetin), two aliphatics-palmitic acid, myricyl palmitate and one naphthoquinone-plumbagin have been isolated. The major constituent plumbag in has been subjected to Schmidt reaction, allylic bromination, oxymercurat ion and demercuration and Thiele-Winter addition. All the natural and react ion products have been characterized by spectroscopic studies.
