Grape leaves influence several biological activities in the cardiovascular system, acting as antioxidants. In this study, we aimed at evaluating effect of ethanolic and water extracts from grape grown Algeria, obtained by accelerator solvent extraction (ASE), on cell proliferation. The amount total phenols was determined using modified Folin-Ciocalteu method, antioxidant were evaluated 2,2-diphenyl-l-picrylhydrazyl free radical (DPPH*) method ·OH scavenging electron paramagnetic resonance...
In view of the increasing interest in natural antimicrobial molecules, this study screened ability Thymus capitatus (TC) essential oil and Citrus limon var. pompia (CLP) extract as raw extracts or incorporated vesicular nanocarriers against Streptococcus mutans Candida albicans. After fingerprint, TC CLP were mixed with lecithin water to produce liposomes, different ratios water/glycerol water/propylene glycol (PG) glycerosomes penetration enhancer vesicles (PEVs), respectively. Neither nor...
`Washington Navel', `Biondo Comune', `Tarocco', and `Valencia Late' orange [ Citrus sinensis (L.) Obsek] fruit, harvested at various periods of time, were subjected to ultraviolet-C (UV-C) irradiation 0.5, 1.5, or 3.0 kJ·m -2 doses then stored 7 °C 90% 95% relative humidity (RH) for 4 weeks plus one additional week 20 80% RH. Following UV-C treatment, there was varying amounts rind browning necrotic peel damage, depending on cultivar, treatment dose, harvest date. `Tarocco' fruit damaged...
Pompia is a Citrus species belonging to Sardinian endemic biodiversity. Health benefits were attributed its flavedo rind extracts and essential oils while the juice qualities have never been investigated. In this paper, antioxidant, antimicrobial, other biological properties of studied. A combined LCMS/electrochemical/biological approach was used clarify still debated phylogeny explain role phenolic compounds. closer phylogenetic relationship with lemon citron, rather than oranges suggested....
A hot-water dip for 2 min at 52−53 °C prevented decay least one week in lemon fruit inoculated with Penicillium digitatum. The mode of action hot water reducing was investigated by studying the effects this treatment on pathogen and resistance mechanisms fruit. had a transient inhibitory effect pathogen, arresting its growth 24−48 h. During lag period, combined induced build up peel. Lignin production sites began within 24 h after inoculation or wounding. When followed dip, lignin...
Star Ruby grapefruit [Citrus paradisi (Macf.)] were harvested in November, February, and May, treated with ultraviolet C (UV-C) light at 0.5, 1.5, or 3.0 kJ.m(-)(2), then stored 7 degrees 90-95% relative humidity (RH) for 4 weeks 1 additional week 20 approximately 80% RH. Untreated fruits used as control. UV-C irradiation 0.5 kJ.m(-)(2) effectively reduced decay development compared to nontreated fruit without causing damage. Irradiation dosages >0.5 did not further improve control caused...
Abstract A diffusion model based on Fick's second law was used to simulate water transport in pear fruit at various conditions (20 °C and 75% RH; 1 60% RH). The finite element method discretise the governing differential equations over actual 3D geometry. For first time, Conference fruits described mesoscale level by incorporating different tissues (cuticle, inner outer cortex) with properties. validated explained well as through nuclear magnetic resonance imaging techniques able predict...
Existing therapeutic strategies for breast cancer are limited by tumor recurrence and drug-resistance. Antioxidant plant-derived compounds such as flavonoids reduce adverse outcomes have been identified a potential source of antineoplastic agent with less undesirable side effects. Here, we describe the novel regulation fatty-acid synthase (FASN), key enzyme in de novo synthesis, whereby Vitis vinifera L. cv Vermentino leaf hydroalcoholic extract lowers its protein stability that is regulated...
Background: Given the increasing request for natural pharmacological molecules, this study assessed antimicrobial capacity of Pistacia lentiscus L. essential oil (PLL-EO) obtained from leaves wild plants growing in North Sardinia (Italy) toward a wide range periodontal bacteria and Candida, including laboratory clinical isolates sp., together with its anti-inflammatory activity safety. Methods: PLL-EO was screened by gas chromatography/mass spectrometry. The minimal inhibitory concentration...
The phenolic composition of Syrah and Chardonnay grape pomaces was studied to assess their antioxidant prooxidant properties. Polyphenols were extracted by a "green" hydroalcoholic solvent (ethanol/water 1:1 v/v), detailed chemical electrochemical characterization the compounds performed. capacity pomace first cyclic voltammetry (CV) other reference analytical assays, then with biological tests on B16F10 metastatic melanoma cancer cells. Electrochemical data showed that, when +0.5 V...
Tarocco blood oranges (Citrus sinensis Linn. Obsek) were harvested monthly from November to April and dipped in water at 53 °C for 3 min before storage 10 weeks 1 additional week 20 °C, which simulated a marketing period (SMP). Untreated fruit used as control. No treatment damage was observed March. In contrast, hot dipping caused severe the peel picked earlier later season. Susceptibility chilling injury (CI) greatest between January, less February, negligible March April. Prestorage...
The influence of the immersion lemon fruit in aqueous imazalil (IMZ) mixtures at 25 or 50 °C on deposition and persistence IMZ within rind its effectiveness controlling postharvest green mold, caused by Penicillium digitatum, was investigated. Concentrations albedo tissue surrounding deep wounds were higher than mean EC50 values for IMZ-resistant strains (1.0 μg·mL−1) after into containing 25, 50, 75 mg·L−1 heated to °C, but not those where fungicide insufficient. residue, one day treatment...
Pistacia lentiscus berry oil (LBO) represents a typical vegetal product of the Mediterranean basin that has been formally used in traditional cuisine for 100s years. In addition to its interesting alimentary properties, this could represent an candidate field research on study new anti-infective agents. fact, countries, lentisk still continues be widely folk medicine oral and skin affections, particular, acute gingivitis, pediatric infections such as impetigo foot plaques, biofilm related...
