The in vitro cytotoxicity, antioxidant and antibacterial potential of Satureja hortensis L. essential oil cultivated in Egypt.

This study was designed to evaluate the antioxidant, antibacterial and cytotoxicity effects of Satureja hortensis (S. hortensis) essential oil (EO). The GC-MS analysis of S. hortensis EO (SEO) has identified seven compounds, representing 96.84% of the oil. The two main constituents of the oil were; carvacrol (48.51%) and γ-terpinene (36.63%). The total phenolics and flavonoids contents of SEO were 199.1 ± 0.5 µg GAE/mg (GAE-gallic acid equivalent) and 161.5 ± 0.9 µg CE/mg (CE-catechin equivalent), respectively. SEO showed superior antioxidant potential (ABTS, 1038.66 and DPPH, 12.679 mg Trolox/g), and exhibited antibacterial activity against five food born bacterial strains, exerting the minimum inhibitory concentration (MIC) ranging from 2 to 4 mg/mL. On the other hand, using of SEO at inhibiting concentrations for pathogenic bacteria can affect the beneficial bacteria negatively. Moreover, SEO showed toxicity on normal cells (WI-38, THLE2, and phoenx-eco) and consequently, it is worthwhile for extensive toxicity studies in normal cells and animal models. As our-knowledge, this is the first study on antioxidant, antimicrobial and cytotoxicity of Egyptian S. hortensis. PMID: 31911310 [PubMed - as supplied by publisher]
