Caffeine, trigonelline and nicotinic acid are important bioactive constituents of coffee. In this work, the combination different water temperatures pressures in settings espresso coffee (EC) machine was evaluated, to assess how these factors influence effectively caffeine, extracted from both Arabica Robusta samples. The proposed analytical method, based on a high performance liquid chromatography (HPLC) system coupled variable wavelength detector (VWD), showed good linearity (R2 > 0.9985)...
Abstract As part of our research on local plants, including neglected horticultural crops to be rediscovered as culinary vegetables, we focused Smyrnium olusatrum , a biennal herb used in cuisine for many centuries by Romans that has now been replaced celery. We investigated the essential oil compositions different plant organs collected 18 populations central Italy (Marche, Umbria, Abruzzo, Tuscany and Latium) gas chromatography (GC) with flame ionization detector GC mass spectrometry (MS)...
We are now seeing an increase in the production of agri-food waste, which is essential resource for recovery bioactive compounds that may be employed as innovative natural ingredients cosmetics. To date, approach to cosmetics preservation has seen a significant shift search biological components give healthier alternatives customers and help businesses operate environmentally friendly manner. achieve this goal, we studied pomegranate extracts using peel and, first time, from male flowers...
The effects of heat-transfer modes on acrylamide (AA), AA precursors, and the main quality characteristics biscuits were investigated. Biscuits baked in ventilated mode (V), with forced air convection, static (S), based only conduction, at 175 °C for 18, 20, 22, 24, 26 min. Both types promoted an increase levels during baking. However, V heat was distributed more evenly compared to S one, causing a faster rise temperature, as showed by recorded time-temperature profiles. As consequence,...
A new, fast and simple analytical method that is able to identify quantify simultaneously 17 steroid hormones metabolites (pregnenolone, 17-OH-pregnenolone, progesterone, 17-OH-progesterone, androsterone, androstenedione, dehydroepiandrosterone, dehydroepiandrosterone sulfate, testosterone, cortisol, corticosterone, aldosterone, 11-deoxycortisol, 11-deoxycorticosterone, dihydrotestosterone, estrone estradiol) has been developed in equine serum using the ultra-high-performance liquid...
Chemical and enzymatic in vivo degradation of antimicrobial peptides represents a major challenge for their therapeutic use to treat bacterial infections. In this work, anionic polysaccharides were investigated ability increase the chemical stability achieve sustained release such peptides. The formulations comprised combination (vancomycin (VAN) daptomycin (DAP)) (xanthan gum (XA), hyaluronic acid (HA), propylene glycol alginate (PGA) alginic (ALG)). VAN dissolved buffer pH 7.4 incubated at...
This project aimed to apply eco-friendly extraction methods Crocus sativus L. by-product (flowers without stigmas i.e., tepals composed of petals and sepals) recover extracts with high antioxidant capacity polyphenol content, be used in cosmetic products. Flowers grown two different Italian regions (Sample 1—Alba Piemonte, north Italy Sample 2—Sibillini Marche, centre Italy) were subjected for the first time microwave-mediated green solvents extractions (MGSE) andquali-quantitative...
To define and control the parameters which impact headspace solid-phase microextraction (HS-SPME), it is important to reach highest level of reproducibility. The present study aims assess, for first time, effect fiber–sample distance during HS-SPME in pre-equilibrium conditions. Analyses were primarily performed on mixtures standard volatiles compounds (alkanes, alcohols, organic acids) designed our lab then various food matrices (wine, chicken, cheese, tea), repeating already published...
<p>Chlorogenic acids (CGA) are a group of phenolic acid derivatives, which commonly found in coffee at concentrations reaching 0.1-0.2%. A method based on high performance liquid chromatography-diode array detector (HPLC-DAD) is proposed for the simultaneous determination three chlorogenic acids, i.e. 3-<em>O</em>-caffeoylquinic (3-CQA), 5-<em>O</em>-caffeoylquinic (5-CQA) and 3,5-di-O-caffeoylquinic (3,5-diCQA), time portions espresso coffee. Two different...
Abstract Nicotinamide, nicotinic acid, nicotinamide mononucleotide, riboside and adenine dinucleotide represent key metabolites through which a variety of cellular processes is regulated. Here, we report quantitative, simultaneous determination their pyridine precursors in several murine tissues using high‐performance liquid chromatography with tandem mass spectrometry method based on reversed‐phase chromatographic separation. All the analytical steps, including sample preparation compounds...
The aim of this work was to provide a characterisation volatile constituents from different commercial batches henna (Lawsonia inermis) leaves geographic origin. Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS) used for the purpose. A total 72 components were identified by GC-MS in headspace samples which proved differ considerably each other, because they characterised classes components, mainly aliphatic compounds (9.0-64.7%),...
A new method for extracting isoflavones from espresso coffee (EC) was coupled with high-performance liquid chromatography-tandem mass spectrometry (MS/MS) the first time to analyse five isoflavones, which included both a glycosilated form, genistin and aglycons daidzein, genistein, formononetin biochanin A. Isoflavones were extracted samples using methanol, stored in freezer overnight precipitate proteic or lipidic residues purified on SPE C18 cartridges before chromatography-MS/MS analysis....
Breast cancer is the most diagnosed among women, and its incidence mortality are rapidly growing worldwide. In this regard, plant-derived natural compounds have been shown to be effective as chemotherapeutic preventative agents. Apricot kernels a rich source of nutrients including proteins, lipids, fibers, phenolic contain aromatic cyanogenic glycoside amygdalin that has exert cytotoxic effect on cells by affecting cell cycle, inducing apoptosis, regulating immune function.Here, we describe...
A simple and fast analytical method able to simultaneously identify quantify 17 endogenous exogenous steroidal hormones was developed in bovine equine blood using UHPLC-MS/MS. total amount of 500 µL sample deproteinized with a mixture methanol zinc sulfate evaporated. The reconstituted 50 solution 25% injected the UHPLC-MS/MS triple quadrupole. correlation coefficients calibration curves analyzed compounds were range 0.9932–0.9999, limits detection quantification 0.023–1.833 0.069–5.5 ppb,...
