Antibacterial And Antioxidant Activity Of Combined Essential Oil From Three Selected Herbs

Abstract

In this research, the combination of essential oils from Citrus maxima peel, Cymbopogon citratus, and Zingiber officinale rhizome with 1:1:1, 1:1:2, 1:2:1, 2:1:1 ratio, respectively, was carried out to test the antimicrobial and antioxidant activities. The minimum inhibitory concentration (MIC) of the antibacterial properties with different ratios of the combination was determined by the disc diffusion method that was effective against both Gram-positive and Gram-negative bacteria including Staphylococcus aureus, and Escherichia coli while using the DPPH free-radical scavenging activity examinations led to determine the antioxidant activities. According to the result, 1:1:2 ratio and 1:2:1 ratio gave the best ratio for antioxidant activities and the antibacterial activities, respectively. In contrast, the 1:1:1 ratio was the lowest ratio for two activities.
