Comparative study of the chemical profiling, antioxidant and antimicrobial activities of essential oils of different parts of <i>Thymus willdenowii</i> Boiss & Reut

<p>The analysis of <i>Thymus willdenowii</i> Boiss & Reut essential oils (TW EOs) shows 33 components accounting for (96.3–97.7%) of all identified. The main constituents of TW EOs were thymol (35.5–47.3%), p-cymene (13.9–23.8%), γ-terpinene (8.9–20.3%). The antioxidant assays revealed that all TW EOs tested showed strong activities, the antimicrobial effect of TW EOs has been tested against isolated clinical strains of <i>Proteus mirabilis</i> (ATCC 35659), <i>Escherichia coli</i> (ATCC 25922), <i>Candida albicans</i> (ATCC 10231), <i>Bacillus cereus</i> (ATCC 10876), and <i>Aspergillus brasilliensis</i> (ATCC 16404). The antimicrobial test indicates that TW EOs show an inhibition effect against all the tested bacteria with a MIC of 6.9 to 27.6 μg/mL⁻¹. These results proving that the essential oils extracted from <i>Thymus willdenowii</i> Boiss & Reut may be a new potential source of natural antimicrobial applied in pharmaceutical and food industries.</p
