Essential oils from Calamintha umbrosa and Nepeta species viz. N. leucophylla; N. hindostana; N. ciliaris and N. clarkei (family Lamiaceae), was tested against six bacterial strains. To evaluate the correlation between the antimicrobial activity and the essential oils, PCA and HCA analysis was done. PCA and HCA analysis of the antibacterial activity revealed that essential oils of Nepeta species had a strong and broad spectrum antibacterial effect against bacterial strains of P. aeruginosa and S. scandidus. The N. leucophylla oil showed higher activity against Gram-negative bacteria P. aeruginosa (10.5 mm, MIC 10 µL/mL) and K. pneumonia (9.1 mm, MIC 45 µL/mL) among all Nepeta oils which may be due to presence of active antimicrobial iridoids compounds.
