In previous work [1], the essential oil of the aerial parts of Marrubium vulgare L. obtained by hydrodistillation was analysed by gas chromatography coupled to mass spectrometry (GC-MS) in order to determine their chemical composition. Fifty (50) components in the oil of M. vulgare were identified. The results demonstrated that the major components of the essential oil were: 4,8,12,16-Tetramethyl heptadecan-4-olid (16.97 %), Germacrene D-4-ol (9.61 %), α- pinéne (9.37 %), Phytol (4.87 %), Dehydro-sabina ketone (4.12 %), Piperitone (3.27 %), δ-Cadinene (3.13 %), 1-Octen-3-ol (2.35 %) and Benzaldehyde (2.31 %). In this study, the antioxidant properties of essential oil were examined. The results showed that this oil can be considered an effective source of antioxidants of natural origin. This is the first report on chemical composition of M. vulgare essential oil cultivated in Algeria and the original study on the antioxidant activity of M. vulgare essential oil. The antioxidant activity was investigated with one method: 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method.

Cymbopogon species from the Poaceae family are widely distributed in the Himalayan region of India and commonly used as flavors, fragrances, cosmetics, and pharmaceuticals. It is known to contain compound citral, which give the lemon scent to many of the plants of the cymbopogon genera. The essential oil of  Cymbopogon flexuosus has high polyphenolic content which is responsible for antioxidant properties.  Beside citral is also used for the synthesis of vitamin B and Ionones. The bioactive potential of Lemongrass and constituent are rapidly increasing which is reflected from growing number of reports being published.  The present study was to know the chemical composition and in vitro antioxidant activity of essential oil of C. flexuosus from Uttarakhand. The essential oils of Cymbopogon collected in the region of Uttarakhand were obtained by hydrodistillation of the leaves and analyzed for chemical composition by GC/MS. The antioxidant activity of essential oils at different concentrations was determined against DPPH radical activity and vitamin C as the standard antioxidant compound.  The IC50    value and percentage of DPPH inhibition were recorded.  Twenty-five compounds were identified in essential oil extracted from leaves representing 93.15% of the oil composition. The yield of essential oil of Cymbopogon was 0.6 + 0.1 %and the major compound in the essential oil was citral (a racemic mixture of two isoforms geranial and nearl) followed by heptenone(1.98%) , linalool(1.65%), geraniol (1.47%), ?-caryophyllene (1.14% ) , limonene (0.92%),  nearl acetate (0.82%), citronellal(0.44 %) and citronellol (0.22%). Radical scavenging capacity (Inhibition, %) of the C. flexuosus essential oil was high (78.19+1.11) at the concentration level of 150 ?g/ml and  IC50 value of the essential oil was 43.67?g/ml.  The data of this study encourages to consider the essential oil of C. flexuosus  as a source of bioactive compounds which may add great industrial value to this crop.

The investigation aimed to study the in vitro and in silico antioxidant properties of Melissa officinalis subsp. officinalis essential oil (MOEO). The chemical composition of MOEO was determined using GC–MS analysis. Among 36 compounds identified in MOEO, the main were beta-cubebene (27.66%), beta-caryophyllene (27.41%), alpha-cadinene (4.72%), caryophyllene oxide (4.09%), and alpha-cadinol (4.07%), respectively. In vitro antioxidant properties of MOEO have been studied in 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging, and inhibition of β-carotene bleaching assays. The half-maximal inhibitory concentration (IC50) for the radical scavenging abilities of ABTS and DPPH were 1.225 ± 0.011 μg/mL and 14.015 ± 0.027 μg/mL, respectively, demonstrating good antioxidant activity. Moreover, MOEO exhibited a strong inhibitory effect (94.031 ± 0.082%) in the β-carotene bleaching assay by neutralizing hydroperoxides, responsible for the oxidation of highly unsaturated β-carotene. Furthermore, molecular docking showed that the MOEO components could exert an in vitro antioxidant activity through xanthine oxidoreductase inhibition. The most active structures are minor MOEO components (approximately 6%), among which the highest affinity for the target protein belongs to carvacrol.

The chemical composition and antimicrobial activity of the essential oils obtained from the flowering aerial parts and ripe fruits of Echinophora spinosa L. (Apiaceae) from central Italy were analyzed by GC/MS. The major constituents of the oil from the aerial parts were β-phellandrene (34.7%), myristicin (16.5%), δ3-carene (12.6%), α-pinene (6.7%) and α-phellandrene (6.2%), and of the oil from the ripe fruits p-cymene (50.2%), myristicin (15.3%), α-pinene (15.1%) and α-phellandrene (8.1%). The two oils showed good antimicrobial activity against Clostridium difficile, C perfringens, Enterococcus faecalis, Eubacterium limosum, Peptostreptococcus anaerobius and Candida albicans with MIC values respectively of 0.25, 0.25, 0.25, 0.25, 2.25, and 0.50%, v/v, and 0.13, 0.13, 0.13, 0.13, 2.25, 0.50%, v/v, for aerial parts and ripe fruits respectively. A less significant antimicrobial activity against bifidobacteria and lactobacilli, very important in the intestinal microflora, was also detected, with MIC values higher than 4.0%, v/v.

The chemical composition was analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The constituents were identified by their mass spectra and Kovats’ indices. Fivety (50) components in the oil of M. vulgare were identified. The results demonstrated that the major components of the essential oil were: 4,8,12,16-Tetramethyl heptadecan-4-olid (16.97%), Germacrene D-4-ol (9.61%), α- pinéne (9.37%), Phytol (4.87%), Dehydro-sabina ketone (4.12%), Piperitone (3.27%), δ-Cadinene (3.13%), 1-Octen-3-ol (2.35%) and Benzaldehyde (2.31%). The antioxidant activity of the oils was assessed by measurement of metal chelating activity, the reductive potential, the free radical scavenging (DPPH) assay. The antioxidant activity was compared with that of synthetic antioxidants: butylated hydroxyanisole (BHT), and the essential oils. The results showed as the Essential oil of M. vulgare was evaluated for its antibacterial activities against Gram-positive and Gram negative pathogenic bacteria: Listeria monocytogene, Pseudomonas aeruginosa, Agrobacterium tumefaciens and Salmonella enterica.
