The well-established health beneficial value of pomegranate juice is leading to increased demand for products and the expansion orchards worldwide. current study describes differences in chemical composition major ingredients arils peels 11 accessions grown Mediterranean desert climates Israel. In most accessions, levels antioxidant activity content total phenolics, anthocyanins, soluble solids, glucose, fructose, acidity were higher aril fruit climate compared those climate. However,...
Low-resolution nuclear magnetic resonance (LR-NMR) relaxometry is a powerful tool that can be harnessed for characterizing constituents in complex materials. Conversion of the relaxation signal into continuous distribution components an ill-posed inverse Laplace transform problem. The most common numerical method implemented today dealing with this kind problem based on L2-norm regularization. However, sparse representation methods via L1 regularization and convex optimization are relatively...
Abstract Aim Woody vegetation patterns in African savannas north of the equator are closely connected to human presence, but distinctions between natural and anthropogenic landscapes have not been clear many observers. Criteria for identifying savanna on a continuum intensity anthropic impact explored. Methods A key tree species, Vitellaria paradoxa (Sapotaceae), was used as model evaluating impact. Fruits harvested from populations across species range were analysed variation traits valued...
Pomegranate oil (PGO) is a unique and quite rare edible produced from Punica granatum L. seeds. It considered to be powerful health-benefiting agent, due its antioxidative, anticancer, antilipidemic properties. The aim of this study was achieve comprehensive detailed profile the different components PGO. fatty acid phytosterol composition were determined by GC-MS; triacylglycerol (TAG) compositions profiled mass spectrometry tool MALDI-TOF/MS. Results showed linolenic (18:3) predominant in...
Indole‐3‐butyric acid (IBA) was much more effective than indole‐3‐acetic (IAA) in inducing adventitious root formation mung bean ( Vigna radiata L.) cuttings. Prolonging the duration of treatment with both auxins from 24 to 96 h significantly increased number roots formed. Labelled IAA and IBA applied basal cut surface cuttings were transported acropetally. With auxins, most radioactivity detected hypocotyl, where formed, but relatively found upper sections The rate metabolism these similar....
Indole-3-butyric acid (IBA) is rapidly metabolized by mung bean cuttings during rooting. Twenty-four hours after application, less than 20% of the applied IBA remained in free form and its level decreased continuously later stages Indole-3-butyrylaspartic (IBAsp) at least two high molecular weight conjugates were major metabolites IBA-treated cuttings. In latter conjugates, part moiety attached to a constituent an amide linkage. IBAsp peaked 24 application then declined. The increased...
1H low field nuclear magnetic resonance (LF-NMR) relaxometry has been suggested as a tool to distinguish between different molecular ensembles in complex systems with differential segmental or whole motion and/or morphologies. In biodiesel applications the structure versus liquid-phase packing morphologies of fatty acid methyl esters (FAMEs) influences physico-chemical characteristics fuel, including flow properties, operability during cold weather, blending, and more. Still, their liquid...
RAPD analysis was performed on the main traditional and introduced varieties of olive grown in Israel West Bank. Primers were identified used combination to discriminate between different varieties. Significant biodiversity demonstrated among `Nabali' trees growing along central mountain ridge Bank, suggesting that grouping known as is actually a mixture genetically distinct variants. On other hand, profiles selected variants `Souri', cultivated mainly northern mountains Israel, revealed...
The triacylglycerol, fatty acid, and polycyclic triterpene compositions of shea butter were determined for 150 samples from the sub-Saharan countries Mali, Burkina Faso, Nigeria, Uganda. compositional profiles showed high variability in all three classes compounds. Shea is made up mainly four triglycerides (TAG) differing carbon number (CN) by two, starting CN 50 to 56. greatest source variation was 54 TAG. characterized 16 saturated unsaturated acids greatly varying proportion, major ones...
Analysis of the phenolic constituents shea (Vitellaria paradoxa) kernels by LC-MS revealed eight catechin compoundsgallic acid, catechin, epicatechin, epicatechin gallate, gallocatechin, epigallocatechin, gallocatechin and epigallocatechin gallateas well as quercetin trans-cinnamic acid. The mean kernel content compounds was 4000 ppm (0.4% dry weight), with a 2100−9500 range. Comparison profiles six major catechins from 40 Vitellaria provenances 10 African countries showed that relative...
The shea tree, Vitellaria paradoxa Gaertner, is the source of a commercial seed fat known as butter. High-performance liquid chromatography (HPLC) analysis tocopherol content butters from different regions Africa showed high variability between provenances and significant effect climate on α-tocopherol levels. total (α, β, γ, δ) in 102 butter samples 11 countries ranged 29 to 805 μg/g butter, with mean 220 μg/g. α-Tocopherol, principal form detected, averaged 64% content. Shea populations...
The effect of aqueous extracts the fruit pulp, seed kernel, roots, bark, and leaves Balanites aegyptiaca Del. (Zygophyllacea) against larvae Culex pipens mosquito was investigated. Early fourth instars C. pipiens mosquitoes were exposed, for up to three days, a dilution 0, 0.1, 0.25, 0.5, 1.0, 2.0% leaves. All tested showed larval mortality, however, mortality greatest with root extract. lowest concentration extract (0.1%) 100% after whereas 0.5% bark needed mortality. Aqueous leaf, kernel...
Triacylglycerols (TAGs), composed of three esterified fatty acids with an attached glycerol backbone, are the main component vegetable oil (approximately 95%) and important source energy nutrition for humans, so their compositional analysis merits extensive interest. Intact TAG composition in native form is highly important, rather than acid profile itself. This paper reports olive oils produced from six common cultivars grown Negev desert Israel (Barnea, Souri, Arbequina, Picual, Leccino,...
