The study was aimed to investigate essential oil chemical composition (gas chromatography/flame ionization detection [GC-FID] and gas chromatography/mass spectrometry [GC-MS]) antioxidant (1,1-diphenyl-2-picrylhydrazyl free radical (DPPH) 2,2'-azinobis-3-ethylbenzothiazoline-6-sulphonate [ABTS] assays) antimicrobial (Gram-positive Gram-negative bacteria, fungi, yeast) activities of oils extracted from leaves Mentha longifolia L. viridis. GC-MS analysis revealed that M. constituted by...
Abstract: Essential oils were obtained by steam distillation from berries of Schinus molle L. and terebinthifolius Raddi originating southern Tunisia analyzed GC‐FID GC‐MS. Among 57 62 compounds (%[mg/100 g dry matter]) identified in these oils, the main α‐phellandrene (46.52%[1256.15] 34.38%[859.60]), β‐phellandrene (20.81%[561.74] 10.61%[265.15]), α‐terpineol (8.38%[226.26] 5.60%[140.03]), α‐pinene (4.34%[117.29] 6.49%[162.25]), β‐pinene (4.96%[133.81] 3.09%[77.30]) p ‐cymene (2.49%[67.28]...
Essential oils obtained by hydrodistillation from the different parts (stems, adult leaves, immature flowers and fruits) of Eucalyptus oleosa were screened for their antioxidant antimicrobial properties chemical composition. According to GC-FID GC-MS, principal compound stem, fruit was 1,8-cineole, representing 31.5%, 47.0% 29.1%, respectively. Spathulenol (16.1%) γ-eudesmol (15.0%) two compounds leaves oil. In DPPH (1,1-diphenyl-2-picrylhydrazyl) assay, four showed moderate activity. ABTS...
is a plant genus that includes annual and perennial species found at various temperatures, from northern temperate regions to tropical subtropical areas. The
Neroli essential oil is extracted from the fragrant blossoms of bitter orange tree. It one most widely used floral oils in perfumery. In this study chemical composition and vitro antimicrobial antioxidant activities neroli are investigated. The fresh Citrus aurantium L. Flowers (Neroli oil) cultivated North East Tunisia (Nabeul) were analyzed by GC-FID GC-MS. About 33 compounds identified, representing 99% total oil. Limonene (27.5%) was main component followed (E)-nerolidol (17.5%),...
Marrubium vulgare is a valuable source of natural bioactive molecules with high preventive and therapeutic effectiveness. Therefore, this study aimed to the chemical polymorphism populations M. in Tunisia by quantitative markers estimation divergence between populations. Phytochemical analyses eight Tunisian prospected different bioclimatic stages, revealed 42 compounds essential oils representing 96.08% 100% total oil. Hydrocarbon sesquiterpenes were main fraction all studied β-bisabolene...
GC-FID and GC-MS analysis of essential oils Juniperus phoenicea resulted in the identification 30 compounds, representing more than 98% total composition. alpha-pinene (55.7% 80.7%), delta-3-carene (10.7% 4.5%), gamma-cadinene (2.9% 5.1%) were main components, respectively, leaves berries oil. Extracts J. obtained by different extraction solvents: methanol, ethanol, ethyl acetate, dichloromethane evaluated composition for polyphenols (gallic acid equivalent 52 to 217 g/kg), tannins (catechin...
Ocimum basilicum is a valuable source of bioactive metabolites with high preventive and therapeutic effectiveness. Here we aimed to investigate the effect phenological stages (vegetative flowering stages) on essential oil composition biological activities two varieties O. (Fino Verde variety Genovese varieties). To this end, level oils, flavonoids phenols, as well antioxidant antifungal were measured. At metabolic level, at vegetative stage bailicum Fino was constituted by 22 26 compounds...
Juniperus phoenicea is an important medicinal plant. In the present study, essential oils (18 samples) from leaves and berries of L. (Cupressaceae), obtained by various drying methods in different collection months, were analysed gas chromatography-mass spectrometry also evaluated for vitro antimicrobial antioxidant activities. Correlations studied between activity chemical composition oils.Sixty-seven compounds identified oils, representing 97.7-100%. Essential dominated monoterpenes...
Okra, Abelmoschus esculentus L., is a popular vegetable crop with many bioactive compounds. The in vitro immunostimulant, cytotoxic, bactericidal and antioxidant activities of ethanolic extracts obtained from different parts okra (leaves, fruits, seeds) were studied. Phytochemical screening hydroalcoholic leaves, fruits seeds revealed significant content total phenols flavonoids. Notable effects on the leukocytes head kidney European sea bass (Dicentrarchus labrax) (viability, phagocytic...
This study investigates the anatomical adaptations of leaves from two halophyte species, Nitraria retusa (Forsskal) Asch. and Atriplex halimus L., in response to pollutants a cement factory human activities. In industrial areas, these plants absorb through their leaf surfaces, including Cu, Zn, Pb. The species were examined for changes under air pollution, key factors blade thickness, palisade parenchyma cell height, spongy diameter, epidermal characteristics, stomatal traits assessed. Under...
Leaf essential oils (EOs) of seven Eucalyptus species from southern Tunisia (E. gracilis, E. lesouefii, salmonophloia, sargentii, flocktoniae, oleosa and salubris) were screened for their antifeedant, nematicidal phytotoxic effects chemical compositions. The yield EOs these varied 1.32±0.38% to 4.92±0.37%. Using gas chromatography mass spectrometry (GC‐MS) analysis, 22 compounds identified, representing 87.16% 96.83% the total oil content. main components found in all 1,8‐cineole...
The present work experimentally investigates the curves of drying kinetics celery leaves (Apium Graveolens L.) in a convective oven. These were determined at 50°C, 60°C, and 70°C. For fitting experimental results, Lewis, Handerson, Pabis, Page, Midilli &Kucuk, Logarithmic, Modified Wang, Singh Two Terms models used. & Kucuk model provided best fit for results. effective water diffusion coefficient (Deff) varied from 3.65×10-10 m2/s to 7.29×10-10 considered temperature range. higher...
