CHEMICAL AND ANTIBACTERIAL PROPERTIES OF KIONS FROM EUCALYPTUS SSP.CITRIODOROL THE ANTIBIOTICPRINCIPLE FROM THE KION OF E . CITRIODOROA

Abstract

The kinos of four Eucalyptus species, viz., E. citriodora, E. robusta,E. pilularis and E. globulus, have been studied for their general physical and chemical characteristics as well as their antibacterial activity against a few representative micro- organisms. Ellagic acid is present in all the four species while glucose could be detected only in E. citriodora and E. globulus kino. In combination, possibly as a glucoside of 7-methylkmmpferol, glucose was found chromatographically in the former kino.The kino from E. citriodora showed considerable activity against Grampositive organisms which warranted the isolation of the active principle.
