The beneficial effects of wine are associated with the physiological protection conferred by phenolic compounds such as anthocyanins and resveratrol. Levels of these phenolic compounds were quantified in 19 monovarietal wines produced in Sicily. Resveratrol and resveratrol-glucosides were detected by high-performance liquid chromatography (HPLC) with an(More)
Considering that the determination of authenticity and of the geographical origin of food is a very challenging issue, in this study we studied by means of histological and histochemical analyses the famous Sicilian lemon known as 'Interdonato Lemon of Messina PGI'. Since the protected geographical indication Interdonato lemon of Messina possesses high(More)
[reaction: see text] The meso-decamethyl-calix[5]pyrrole 2b was synthesized from the furan-based analogue 1b via the homologation of the furan rings to pyrrole, and its solid-state structure was determined by X-ray crystallography: surprisingly, the binding constant of 2b toward chloride is found to be lower than that of the tetrameric analogue 2a.
Ethanol production by fermentation is strongly dependent on media composition. Specific nutrients, such as trace elements, vitamins and nitrogen will affect the physiological state and, consequently, the fermentation performance of the micro-organism employed. The purpose of this study has been to assess the highest ethanol production by a minimal medium,(More)
This data set is composed to assess the accumulation of persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs) dioxin like (DL) and not dioxin like (NDL), organochlorine pesticides (POCs) and polycyclic aromatic hydrocarbons (PAHs) in Thunnus thynnus and to elucidate the suitability of this species as a bioindicator for monitoring(More)
A fast reversed-phase UPLC method was developed for squalene determination in Sicilian pistachio samples that entry in the European register of the products with P.D.O. In the present study the SPE procedure was optimized for the squalene extraction prior to the UPLC/PDA analysis. The precision of the full analytical procedure was satisfactory and the mean(More)
In the present study we report on the optimization and validation of a sensitive high performance liquid chromatography atmospheric pressure chemical ionization mass spectrometry (HPLC-APCI-MS) method for the determination of 8 bioactive amines (histamine, tyramine, tryptamine, 2-phenylethylamine, cadaverine, putrescine, spermidine and spermine) in donkey(More)
Considering the crucial role of carotenoids exploitable both as nutraceuticals and also as dyes in food industry, there are many efforts in seeking for new sources of these pigments, especially in the marine world. In this study, for the first time, we extracted carotenoids from sea sponges Raspaciona aculeata and Dictyonella marsilii taken from Ganzirri(More)
This study is aimed to monitor by 1H NMR spectroscopy the effect of a 12-month storage period on the 1,2-diglycerides over 1,3-diglycerides ratio for five mono-cultivar 'extra virgin olive oils' (EVOO) (Arbequina, Arbosana, Cerasuola, Nocellara and FS17) and one blend of two different cultivars (Nocellara + Biancolilla) preserved in the dark and at room(More)
Calix[6]pyrrole 2 and the "hybrid systems" calix[3]furan[3]pyrrole 12, calix[2]furan[4]pyrrole 13, and calix[1]furan[5]pyrrole 14, have been synthesized by increasing conversion of the furan units present in the readily accessible calix[6]furan 3 to pyrroles. The host-guest chemistry of these novel macrocycles towards a number of anions, including halogen(More)
