bacterial species. The phenyl m-nitro substituted derivative (13) showed a mild
antimicrobial activity against Escherichia coli and remained inactive against other
experimental bacteria. The m-chloro aryl (14) and m, p-dichloro aryl (15) derivatives showed the most potent activity against all bacteria except Escherichia coli;
whereas, the naphthyl-substituted derivative of carvacryl ether (16) exhibited more
potent antibacterial activity than carvacrol against Proteus vulgaris, and Bacillus
