Free Radical Scavenging Activities

The chemical composition of the essential oil from roots and rhizomes of Ligularia hodgsonii was analyzed by gas chromatography (GC) and GC-mass spectrometry (MS). Forty-seven components were identified, representing 77.0% of the total oil. The main constituents were l-(+)-ascorbic acid 2,6-dihexadecanoate (15.7%), selina-6-en-4-ol (8.4%) and 9,10-dimethyl-1,2,3,4,5,6,7,8-octahydroanthracene (6.6%). The free radical scavenging activities of the essential oil, aqueous extract, ethanolic extract, and crude polysaccharides of L. hodgsonii, as well as some of their major components, were investigated using DPPH and ABTS assays. The essential oil displayed a lower capacity to quench free radicals than the extracts; the ethanolic and aqueous extracts showed considerably higher antioxidant potential that deserves further study.

Artemisia Dracunculus

Free radical scavenging activity, total phenolic content and the chemical composition of the essential oil isolated by steam distillation from Artemisia dracunculus L. was investigated. The isolation yield was 0.24% (v/w) based on the fresh plant material (leaves). GC-MS investigation identified 21 components, accounting 99.93% of the total amount. The major components were sabinene (42.38%), isoelemicin (12.91%), methyl eugenol (9.09%), elemicin (7.95%) and beta-ocimene (6.46%). The free radical scavenging activity of the essential oil of Artemisia dracunculus L. was evaluated in vitro by the DPPH assay (IC50 = 0.730 � 0.213 mg/mL), BHA and alpha-tocopherol were used as a positive control. The total phenolic content of the tarragon essential oil was evaluated by the Folin-Ciocalteu method (GAE = 0.451 � 0.001 mg/g sample). In view of these data, we consider that tarragon essential oil could represent a new antioxidants source as a reliable option to reduce the usage of synthetic additives.

The chemical composition of the essential oils obtained from aerial parts of Nepeta alatavica Lipsky, N. nuda L., and N. olgae Regel (Lamiaceae), growing wild in Central Asia (Tajikistan and Uzbekistan), were analyzed by GLC and GLC-MS. The main constituents of the essential oil from N. nuda were 1,8-cineole (24.6%), 4a-α,7-β,7a-α-nepetalactone (21.0%), germacrene D (13.5%), and β-caryophyllene (12.7%), whereas those of N. alatavica were thymol (48.5%), verbenone (7.7%), and carvacrol (7.5%). In the essential oil of N. olgae the most abundant compounds were acetylcyclohexene (31.5%), 4-tridecyne (13.2%), 2-methyl cyclopentanone (6.8%) and 1,8-cineole (6.0%). The potential antioxidant activity of these essential oils was studied by using DPPH, ABTS and FRAP assays. The essential oil of N. alatavica showed the highest in vitro free radical scavenging activity, probably due to its high thymol and carvacrol content.

Background: The essential oil from the Acantholimon genus have been an integral part of the traditional food additive in Middle East. Most of the plants in Acantholimon genus have not been studied scientifically. The aim of this study is to investigate the chemical composition, antibacterial, insecticidal and anti-oxidant activities of three Acantholimon species including Acantholimon atropatanum, A. gilliatii and A. tragacanthium. Method: The essential oils of the aerial parts were extracted by hydrodistillation. Chemical constitutions were identified by gas chromatography- mass spectroscopy technique, also their toxicities were assessed against the two important grain products pests, Oryzeaphilus mercator and Tribolium castaneum. Antibacterial activity was assessed against the three foodborne bacteria that include Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus based on the disc diffusion assay. Free-radical-scavenging property was identified based on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Results: 2-hexahydrofarnesyl acetone was the main compound in A. gilliatii and A. tragacanthium, whilst farnesyl acetone, heptacosane and germacrene D were the principal components of A. atropatanum essential oil. These oils exhibited 40-90% mortality of O. mercator and/or T. castaneum at a dose of 12 μl/l air after 48h of exposure, and exhibited significant free-radicalscavenging property (RC50 = 3.7 × 10-3 - 8.3 × 10-3 mg/ml). The oils of A. tragacanthium and A. gilliatii showed a weaker antibacterial activity compared to A. atropatanum. Conclusion: A. atropatanum, A. gilliatii and A. tragacanthium essential oils had significant insecticidal and anti-oxidant properties. They also showed week to moderate antibacterial activity against P. aeruginosa and S. aureus.

Oregano (Poliomintha longiflora) essential oil (Ooil) is a product of high commercial value and many applications, including chemotherapy. Aiming to achieve the best use of this resource, the present study focuses on the characterization of separated fractions of Ooil by fractional vacuum distillation at low pressure. Four fractions (F1–F4) and undistilled oil (Unoil) were separated from Ooil and analyzed for their chemical composition and biological activities, such as antioxidant and antimicrobial activities. Gas chromatography–mass spectrometry shows differences in the composition among the fractions and Ooil. The amount of monoterpenes oxygenated (MO), sesquiterpenes hydrocarbon (SeH) and monoterpenes hydrocarbon (MH) varied between the fractions in ranges of 1.51–68.08, 3.31–25.12 and 1.91–97.75%, respectively. The major concentrations of MO and SeH were observed in F4 and Unoil. On the other hand, the highest concentrations of MH were found in F1 and F2, while the lowest were in F4 and Unoil. These results were correlated with the biological activity. Free-radical scavenging activity varied among fractions, with F4 and Unoil showing the highest activity. The antimicrobial test showed that F4 and Unoil had the highest activity in almost all cases. The correlation between the variables studied in the different fractions allows the definition of the particular properties for each one of them.
