Virgin olive oil has a high resistance to oxidative deterioration due its tryacylglycerol composition low in polyunsaturated fatty acids and the presence of group phenolic antioxidants composed mainly polyphenols tocopherols. We isolated several compounds extra virgin (phenyl-ethyl alcohols, lignans, secoiridoids) by semipreparative high-performance liquid chromatography (HPLC) identified them using ultraviolet, atmospheric pressure chemical ionization, electrospray ionization MS detection....
Electrochromic effect and molecularly imprinted technology have been used to develop a sensitive selective electrochromic sensor. The polymeric matrices obtained using the imprinting are robust molecular recognition elements potential mimic natural entities with very high selectivity. behavior of iridium oxide nanoparticles (IrOx NPs) as physicochemical transducer together polymer (MIP) layer resulted in fast efficient translation detection event. sensor was fabricated screen-printing indium...
An electroanalytical lab-on-a-strip device for the direct extra-virgin olive oil (EVOO) antioxidant capacity evaluation is proposed. The lab-made composed of a CO2 laser nanodecorated sensor combined with cutter-plotter molded paper-strip designed EVOOs sampling and extraction. Satisfactory performance towards most representative o-diphenols i.e., hydroxytyrosol (HY) oleuropein (OL) were achieved; good sensitivity (LODHY = 2 µM; LODOL 0.6 µM), extended linear ranges (HY: 10-250 OL: 2.5-50...
Nano-PCR is a recent tool that used in viral diseases diagnosis. The technique depends on the fundamental effects of gold nanoparticles (AuNPs) and considered very effective sensitive diagnosis different including diseases. Although several techniques are currently available to diagnose foot mouth disease virus (FMDV), highly sensitive, specific needed for disease. In present work, novel AuNPs biosensor has been designed using thiol-linked oligonucleotides recognize conserved 3D gene FMDV....
Antioxidant activity of the phenolic fraction extra virgin olive oil (EVOO) was measured by means a chemical and an electrochemical method. Both methods were tested in predicting oxidative spoilage stability to oxidation 22 EVOO samples resulted correlated with peroxide values Rancimat. The main compounds EVOOs detected HRGC. To study contribution single polyphenols (PPs) antioxidant EVOOs, multivariate statistical analyses applied on HRGC data. An isomer oleuropein aglycon shown affect...
The phenolic fraction of virgin olive oil influences both its quality and oxidative stability. One the principal threats fruit is fly ( Bactrocera oleae) as it alters chemical composition. attack this pest has been studied in order to evaluate influence on (free acidity, peroxide value, fatty acid composition, water content, stability, phenols, antioxidant power fraction). study was performed using several oils obtained from olives with different degrees infestation. They were acquired...
In this work, a rapid and simple gold nanoparticle (AuNPs)-based colorimetric assay meets new type of synthesis AuNPs in organic medium requiring no sample extraction. The extraction-free approach strategically involves the use dimethyl sulfoxide (DMSO) acting as an solvent for simultaneous analyte solubilization stabilization. Moreover, DMSO works cryogenic protector avoiding solidification at temperatures used to block synthesis. addition, chemical function stabilizers endogenous fatty...
Polyphenols are widespread in vegetables and fruits. They can play an important role human diet health, they influence the sensorial properties of many foods, act as natural antioxidants. This study was conducted using HPLC/DAD, tyrosinase biosensor, differential pulse voltammetry (DPV) analyses to detect polyphenolic compounds complex matrices. The were applied a series both standards extracts derived from grape, olives, green tea. pure include phenolic acids, flavones, flavonols,...
Lipid composition is expected to play an important role in modulating membrane enzyme activity, particular if the substrates are themselves lipid molecules. A paradigmatic case FAAH (fatty acid amide hydrolase), critical terminating endocannabinoid signalling and therapeutic target. In present study, using a combined experimental computational approach, we show that lipids modulate structure, subcellular localization activity of FAAH. We report dimer stabilized by bilayer shows higher...
