Evaluation of Antibacterial and Antioxidant Effects of Mix Essential Oil for Oral Health Care

Abstract

: Essential oil have some antioxidant and antimicrobial properties. The aim of this study was to determine the chemical compounds, antioxidant and antimicrobial activities of essential oil. The analysis of the mix essential oil was carried out using gas chromatography mass Spectrometry. The antioxidant activity of the essential oil was also evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. Antimicrobial properties of the essential oil were assessed against Enterococcus faecalis, Streptococcus mutans, Streptococcus sanguinis using the disk diffusion method. Free radical scavenging potentials showed values for IC 50 in 194 µg/ml for mix essential oil, which are close to the natural antioxidant (ascorbic acid) with an IC 50 of 2.98 µg/mL. The major of mix essential oil were α -pinene (24.54%), D-limonen (18.00%), cis-1- methyl-4-(1-methylethenyi)-l-cyclohexane (14.95%), 3-carene (8.92%), L-menthone (8.26) and β -pinene (5.72%).
