preparation of some new spiro-substituted 4-hydroxypyranoquinolinones and their corresponding dihydropyrano cis-diols is described. The freeradical scavenging activity of the compounds was determined by means of their interaction with the stablefreeradical 1,1-diphenyl-2-picrylhydrazyl (DPPH) and the superoxide anions generated by the enzymic xanthine-xanthine oxidase system. The spiroadamatylpyranoquinolinone
