“…These results are in accordance with previous studies [59][60][61], where essential oils increased the antioxidant effects in in vitro and in vivo systems (HepG2, IEC-6, hepatocytes of rat and mice). The results of Placha et al [62] demonstrated that lower concentrations of EOs improve the health status of animals. Total antioxidant status in plasma significantly increased in a group of birds with their diet supplemented with an EO (sage oil).…”

In this study, we determined the antimicrobial activity of ten essential oils (EOs)—oregano, thyme, clove, arborvitae, cassia, lemongrass, melaleuca, eucalyptus, lavender, and clary sage—against drug-resistant microorganisms previously isolated from patients with skin infections. The essential oil compositions were determined using gas chromatography coupled to mass spectrometry (GC/MS). The assayed bacteria included Pseudomonas aeruginosa, Proteus vulgaris, Citrobacter koseri, and Klebsiella pneumoniae. Two drug-resistant yeasts (Candida albicans and Candida parapsilosis) were also involved in our survey. Oregano, thyme, cassia, lemongrass and arborvitae showed very strong antibacterial and antifungal activity against all tested strains. These results show that these essential oils may be effective in preventing the growth of the drug-resistant microorganisms responsible for wound infections. In this study, the genotoxic effects of tested essential oils on healthy human keratinocytes HaCaT were evaluated using the comet assay for the first time. These results revealed that none of the essential oils induced significant DNA damage in vitro after 24 h. Moreover, the treatment of HaCaT cells with essential oils increased the total antioxidant status (TAS) level. The obtained results indicate that EOs could be used as a potential source of safe and potent natural antimicrobial and antioxidant agents in the pharmaceutical and food industries.

“…Plant-derived essential oils and lipid-soluble bioactive compounds have gained attention for biological roles due to their higher bioavailability compared to water-soluble bioactive compounds. Recently, some essential oils extracted from plants have been reported to have antioxidant effects through scavenging radicals and inducing antioxidant enzymes [17][18][19]. Lavandula angustifolia (true lavender or English lavender) is a well-known aromatic plant rich in volatile oil which is frequently reported to contain linalool (20-50% of the fraction) and linalyl acetate (25-46% of the fraction) as the major oil constituents [20].…”

Lavender is a commonly used herb in traditional medicine in Asia and Europe. It has been reported to be an effective medical plant in treating inflammation, depression and stress, thanks to its sedative and anxiolytic action, thrombotic, and antimicrobial properties. In the present study we investigated the protective effects of essential oil from Lavandula angustifolia (LO) against hydrogen peroxide and tert-butyl hydroperoxide -induced DNA damage. Also the effects of LO on the levels of enzymatic and non-enzymatic antioxidants (SOD-superoxide dismutase, GPx-glutathione peroxidase, GSH-glutathione) were evaluated in in vitro (human hepatoma cell line HepG2) and in ex vivo (freshly isolated rat hepatocytes) systems. The results showed that the oxidant-induced DNA lesions were significantly reduced in both systems pre-treated with the Lavandula angustifolia. The observed DNA-protective activity could be explained by both elevation of GPx activity in cells pre-treated with LO and antioxidant activity of LO.

Current State of the Art on the Antioxidant Activity of Sage (Salvia spp.) and Its Bioactive Components

2020

Common sage (Salvia spp., with the most common species Salvia officinalis) is an important medicinal and aromatic plant due to its bioactive components, secondary products of its metabolism. These components are mainly phenolics, terpenoids, polyphenols, and flavonoids. Many studies have identified their important role in fighting oxidative stress in cells and organisms, together with their anticancer, antimicrobial, and anti-inflammatory role. There are many methods measuring the antioxidant activity of sage phenolic components, usually based on radical scavenging of free radical species, such as 2,2-diphenyl-1-picrylydrazyl and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), and determining the absorbance of the reduced product by a photometric assay. In addition, there are several in vitro and in vivo studies determining the protection of sage extracts in cells in culture or animals, respectively, after induction of oxidative stress. In this review, results from the currently available studies that unravel the significant role of sage bioactive compounds, as antioxidant compounds, and the variety of methods used have been critically analyzed and discussed.
