Antibacterial Activity Studies of Essential Oils from Red Sage (Lantana Camara)

Résumé

Abstract Essential oils are important source of rich medicinal compounds. They are highly volatile, aromatic compounds from natural origins. The essential oils cause the hydrophobility of the bacteria cytoplasm, resulting to the cell wall degradation. The recent activity studies of Lantana camara have mapped out the need to investigate the antibacterial potency of its essential oil. Herein, the result and discussion of the characterization with their antibacterial activity of Lantana camara was reported; the Minimum inhibitory concentration (MIC) on the bacteria (Positive and Negative Gram) with Ciprofloxacin a known antibiotic as the positive control. The broth and agar diffusion method were used in estimating Zone of the inhibition. Oil show moderate antibacterial potency with respect to each of the bacterium used; the potency tends to increase considerably with increase in concentration (25% <50% < 80% < 100%). The zone of inhibition exhibited by the assay at 100% concentration of the essential oil on E. coli was the closest shown to that of the control (ciprofloxacin), also the MIC on E. coli at 100% concentration of the essential oil was greater than that of the control (ciprofloxacin). Consequently, essential oils from lantana camara becomes a wellspring of antibiotics for restraining bacteria action.
