    • Abstract

       

      Gossypin has been ethylated and hydrolysed. The resulting pentaethyl ether of gossypetin is further methylated and the product converted into tetra-ethyl tambuletin by alkali fission and condensation of the ketonic product with the anhydride and sodium salt ofp-ethoxy benzoic acid. This confirms the relationship between gossypin and tambuletin.
