Antibacterial, Antifungal Properties and Chemical Composition of Essential Oils of Satureja hortensis L. and Satureja khuzestanica Jamzad

Abstract

<strong>Background & Aim: </strong>The aim of this study was to investigate the antibacterial, antifungal properties and chemical composition screening of essential oils of <em>Satureja khuzestanica</em> Jamzad and <em>Satureja hortensis</em> L.<br /> <strong>Experimental: </strong>For determination of antibacterial and antifungal activity of these essential oils, <em>Staphylococcus aureus</em> and <em>Candida albicans</em> were targeted, respectively. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of each essential oil were determined individually. Also, chemical composition of essential oils was identified and characterized by gas chromatography armed by mass spectrometry (GC–MS).<br /> <strong>Results: </strong>The total of 22 and 21 compounds were identified in the essential oils of aerial parts of <em>S. hortensis</em> and <em>S. khuzestanica,</em> respectively. The major components of <em>S. hortensis</em> essence were carvacrol (56.36%), γ-terpinene (24.75%), p-cymene (5.81%) and the major constituents of <em>S. khuzestanica</em> essence was reported carvacrol (69.62%), γ-terpinene (9.25%) and p-cymene (8.36%). The obtained results showed the antibacterial and antifungal activity of both extracted essential oils against the tested pathogens. The MIC and MBC of <em>S. hortensis</em> and <em>S. khuzistanica</em> essential oils against <em>S. aureus</em> were determined 0.1 and 0.5 μl/ml, and 0.1 and 0.2 μl/ml against <em>C. albicans</em>, respectively.<br /> <br /> <br /> <br /> <br /> <br /> <strong>Recommended applications/industries: </strong>The results showed that <em>S.hortensis</em> oil had higher antimicrobial activity compare to <em>S. khuzistanica.</em>
