Essential oils and their components are becoming increasingly popular as naturally occurring antimicrobial agents. In this work the chemical composition properties of Thymus essential main were determined. Three obtained from different species growing wild in Sardinia a commercial sample capitatus oil analysed. The identified by GC/MS analysis. activity was determined against panel standard reference strains multiple food-derived spoilage pathogenic bacteria, using broth microdilution...
Quince (Cydonia oblonga Miller) fruit aqueous acetone extracts were evaluated. High-performance liquid chromatography−diode array detection and electrospray ionization−mass spectrometry used for the identification quantification of phenolic compounds. The total content pulp peel parts ranged from 37 to 47 105 157 mg/100 g fresh weight, respectively. Chlorogenic acid (5-O-caffeoylquinic acid) was most abundant compound in (37%), whereas rutin (quercetin 3-O-rutinoside) main one (36%). radical...
Dietary habits may strongly influence intestinal homeostasis. Oxysterols, the oxidized products of cholesterol present in cholesterol-containing foodstuffs, have been shown to exert pro-oxidant and pro-inflammatory effects, altering epithelial layer thus contributing pathogenesis human inflammatory bowel diseases colon cancer. Extra virgin olive oil polyphenols possess antioxidant anti-inflammatory properties, concentrate lumen, where help preventing diseases. In study we evaluated ability...

Saffron (Crocus sativus) floral by-products are a source of phenolic compounds that can be recovered and used in the nutraceutical, pharmaceutical, or cosmetic industries. This study aimed to evaluate compounds’ extraction using green techniques (GETs) saffron explore influence selected on phytochemical composition extracts. Specifically, ultrasound-assisted (UAE), subcritical water (SWE), deep eutectic solvents (DESE) were used. Phenolic identified with (HR) LC-ESI-QTOF MS/MS analysis,...
The chemical composition of the volatile fraction myrtle (Myrtus communis L.) alcoholic extracts and essential oils from leaves berries collected in different places Sardinia (Italy) was studied. A simple rapid liquid−liquid extraction method used to isolate compounds followed by GC GC-MS analysis allowing detection 24 compounds. characterized terpenes corresponding that a fatty acid ethyl esters fraction. variation during evaluated. Essential were obtained hydrodistillation, yields on...
Strawberry tree honey, due to its characteristic bitter taste, is one of the most typical Mediterranean honeys, with Sardinia being largest producers. According specific chemical studies, homogentisic acid was identified as a possible marker this honey. This work, based on HPLC-DAD-MS/MS analysis strawberry (Arbutus unedo L.) previously selected by sensory evaluation and melissopalynological analysis, showed that, in addition above-mentioned acid, there were other high levels substances...
During the liquid chromatographic study of phenolic fraction monofloral honeys was detected in asphodel honey (Asphodelus microcarpus Salzm. et Viv.) chromatogram a distinctive peak not other such as Arbutus unedo L., Hedysarum coronarium, Eucalyptus spp., and Galactites tomentosa. After thin layer chromatography (TLC) purification characterization by NMR LC-MS/MS, compound identified methyl syringate (MSYR) confirmed against an original standard. Levels MSYR were measured 2005, 2006, 2007...
Abstract: Radical scavenging activities of Crocus sativus petals, stamens and entire flowers, which are waste products in the production spice saffron, by employing ABTS radical method, were determined. At same time, metabolic profiles different extract (obtained flowers) obtained LC‐ESI‐IT MS (liquid chromatography coupled with electrospray mass spectrometry equipped Ion Trap analyser). LC‐ESI‐MS is a techniques largely used nowadays for qualitative fingerprint herbal extracts particularly...
Neem oil, a plant-derived product rich in bioactives, has been incorporated liposomes and hyalurosomes modified by adding argan oil so called argan-liposomes argan-hyalurosomes. Argan also added to the vesicles because of its regenerative protective effects on skin. In light this, were specifically tailored protect skin from oxidative stress treat lesions. Argan-liposomes smallest (~113 nm); addition sodium hyaluronate led an increase vesicle size (~143 nm) but it significantly improved...
Grape pomace represents 60%, by weight, of the solid side-streams wine-making process. The quantities produced, seasonality, and presence polyphenols pose economic environmental issues that require proper management approaches based on principles sustainability circular economy. present work focuses combined application solid–liquid extraction from ground grape using a hydroethanolic mixture composting exhausted pomace. obtained results support possibility recovering approximately 76.5 g...
Analysis of organic acids in strawberry-tree (Arbutus unedo) honey showed the presence an unknown acid as main constituent. This compound was isolated and identified homogentisic (2,5-dihydroxyphenylacetic acid) by MS NMR techniques. Its average content 378 ± 92 mg/kg. nectar confirmed floral origin found honey. Since this not detected any different monofloral honeys, it could be used a marker (A. Keywords: Homogentisic acid; unedo); honey;
