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.

在埃及种植的Satureja hortensis L.精油的体外细胞毒性,抗氧化剂和抗菌潜力。

这项研究旨在评估Satureja hortensis(S. hortensis)精油(EO)的抗氧化,抗菌和细胞毒性作用。对山楂链球菌EO(SEO)的GC-MS分析确定了七种化合物,占石油的96.84%。油的两个主要成分是:香芹酚(48.51%)和γ-萜品烯(36.63%)。SEO的总酚和类黄酮含量分别为199.1±0.5 µg GAE / mg(GAE-没食子酸当量)和161.5±0.9 µg CE / mg(CE-儿茶素当量)。SEO表现出优异的抗氧化潜能(ABTS,1038.66和DPPH,12.679 mg Trolox / g),并且对五种食源性细菌菌株均表现出抗菌活性,其最低抑制浓度(MIC)为2-4 mg / mL。另一方面,以致病菌抑制浓度使用SEO可能会对有益细菌产生负面影响。此外,SEO对正常细胞(WI-38,THLE2和phoenx-eco)显示出毒性,因此,对于在正常细胞和动物模型中进行广泛的毒性研究是值得的。作为我们的知识,这是埃及山羊草的抗氧化剂,抗微生物剂和细胞毒性的第一项研究。
