High-performance liquid chromatography was used to determine carotenoids (beta-carotene, lutein, neoxanthin, and violaxanthin) tocopherols of leaves, buds, flowers Tunisian Capparis spinosa. This plant shows strong resistance hard environmental conditions, it is one the most commonly found aromatics in Mediterranean kitchen. In this study, means total were 3452.5 +/- 1639.4, 1002 518.5, 342.7 187.9 microg/g fresh weight (FW) flowers, respectively. Lutein accounts for high content....
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...
Abstract Eucalyptus is a plant frequently present and cultivated in arid regions because of its high adaptation to drought. Furthermore, it known by numerous species which represent s great opportunity choose several tolerant with variable uses. Therefore, the choice species, hybrids or genotypes resistant aridity becomes necessity before any plantation countries characterized semi-arid, Saharan climates. Our review shows an important effect drought on anatomical, physiological biochemical...
ABSTRACT Capparis spinosa is widely distributed all over the Mediterranean Basin. Fatty acid composition of oils C. from seven Tunisian regions was determined. The oil content seeds ranged 23.25 to 33.64% on a dry weight basis. Unsaturated fatty acids accounted for majority acids. Oleic with 45.82% main followed by linoleic (25.37%), palmitic (15.93%), palmitoleic (4.55%) and stearic (4.06%). seed also contained high level tocopherols (ca. 628 mg/100 g). γ‐Tocopherol major homologue 92%),...
Aims: Seed size, shape and colour intensity were compared in castor bean (Ricinus communis L.) grown the field twelve locations corresponding to four climatic regions Tunisia.Study Design: Seeds obtained from plants Tunisia.Place Duration of Study: Samples taken summer 2014 growing spontaneously.Methodology: Size is estimated as area seed images.Shape measured by roundness J index that gives percent similarity figure plane a with an ellipse.Colour gray images.Results: Among parameters...
Caper is a perennial shrub of the Mediterranean Basin. The most important economical species Capparis spinosa. Sterols C. spinosa seed oil isolated from seven Tunisian stands were identified and quantified. contained high levels phytosterols (2240.4 mg/kg total extracted lipids), which -sitosterol, with 1390 mg/kg, was abundant (57.53%). Campesterol stigmasterol accounted for 382 265 respectively (17.05 11.85% sterols, respectively). also contained level 5-avenasterol (6%). We detect...
The aim of the current work was to study for first time phytochemical profile Ephedra alata subsp. alenda seeds extract (ESS). characterized using high-performance liquid chromatography coupled electrospray ionization quadropole time-of-flight mass spectrometry (HPLC–ESI–QTOF/MS). antioxidant and antihemolytic properties were evaluated, inhibitory against α-amylase, α-glucosidase, acetylcholinesterase assessed. Chromatographic analysis revealed that ESS rich in bioactive components including...
Morphological description of seeds is a required step for analysis biodiversity in natural populations and may give clues to adaptive strategies species evolution.A cardioid the curve described by point one circumference rolling around another equal radius.Models based on adjustment seed shape with curves have been Arabidopsis thaliana model legumes Lotus japonicus Medicago truncatula.In this work applied analyze morphology two subspecies Capparis spinosa growing Tunisia.Adjustment images...
Se sembraron en el sur de Túnez (Gabès) semillas ocho accesiones Jatropha curcas (seis americanas y dos africanas) para estudiar sus propiedades agrícolas desarrollo condiciones locales semiáridas. Los caracteres observados incluyen aspectos generales del planta (altura, circunferencia follaje, número nodos producción semillas); características las hojas (longitud peciolo, longitud limbo, anchura limbo superficie foliar); la semilla (tamaño forma). El análisis morfológico incluyó área...
Fifteen Tunisian wild populations of caper (Capparis spinosa L.) from different geographical regions, including inerm and thorny morphotypes were assessed for their phenotypical variation using eight morphological traits. The type is restricted to the North country, while wildly distributed South. data underwent an analysis variance a multivariate analysis. Significant differences among descriptors observed. level was high belonging type. PCA HAC groupings performed on all measured...
Phosphogypsum (PG) was used as substrate for the multiplication of eight ornamental species; six by cuttings and two sowing. The results obtained showed a high rooting or percent germination plants: Ficus benjamina, Pelargonium × Hortorum, Washingtonia filifera, Eucalyptus camaldulensis, Hibiscus rosa sinensis Acalypha wilkesiana. For percentage 50% PG, only F. H. W. filifera rooting. Plant vigour (height biomass) depends on both species treatment. Two sensitivity to PG during propagation...
