| مستخلص: | Research background. Extracts from grape pomace, including the wine, show many biological effects such as antioxidant and anti-inflammatory activities. Unfortunately, winemakers discard the bagasse, so the waste is not exploited, although it contains bioactive compounds with antioxidant and anti-inflammatory properties. The work aims to analyze the hydroethanolic extract of peels from Vitis labrusca agro-industrial waste and to evaluate its antinociceptive and anti-inflammatory properties. This study is relevant for reusing a residue and adding value to the grape economic chain. Experimental approach. A representative sample of pomace was obtained and the peels were used to produce the extract. The phenolic compounds were determined by mass spectrometry in multiple reaction monitoring mode and Folin-Ciocalteu colorimetric method, using gallic acid as standard. The biological analyses were carried out using mice orally treated with crude extract at doses of 30, 100 and 300 mg/kg. We evaluated mechanical hyperalgesia by the von Frey method, thermal heat hyperalgesia using a hot plate at 55 °C, paw edema using a pachymeter, and neutrophil recruitment by measurement of myeloperoxidase activity. The nephrotoxicity and hepatotoxicity were evaluated by biochemical analyses using blood samples that were collected after the Vitis labrusca administration. Results and conclusions. In all wet winemaking residues peel mass fraction was 75%, and in dry residues 59%. We identified nine anthocyanins (3-O-glucosides: peonidin, delphinidin, petunidin and malvidin; 3-p-coumaroyl-glucosides: cyanidin, peonidin, petunidin and malvidin, and malvidin-3,5-diglucoside), five flavonoids (apigenin-7-glucoside, luteolin-7-glucoside, quercetin-3-galactoside, isorhamnetin-3-glucoside and myricetin-3-rutinoside), and mass fraction of phenolic compounds, expressed as gallic acid equivalents, was 26.62 mg/g. In vivo assays showed that Vitis labrusca extract at mass fractions 100 and 300 mg/kg reduc Pozadina istraživanja. Ekstrakt komine grožđa, kao i vino, ima mnoga biološka svojstva, poput antioksidacijskog i protuupalnog učinka. Nažalost, proizvođači vina odbacuju neiskorišteni trop iako sadržava bioaktivne spojeve s antioksidacijskim i protuupalnim svojstvima. Svrha je ovoga rada bila ispitati antinociceptivna i protuupalna svojstva vodeno-etanolnog ekstrakta pokožice grožđa vrste Vitis labrusca iz agroindustrijskog otpada. Značaj je ovoga istraživanja u tome što se korištenjem otpada daje dodatna ekonomska vrijednost grožđu u uzgojnom lancu. Eksperimentalni pristup. Ekstrakt je dobiven iz pokožica izdvojenih iz reprezentativnog uzorka komine. Udjel fenolnih spojeva određen je praćenjem višestrukih reakcija pomoću masene spektrometrije i metodom Folin-Ciocalteu, uz galnu kiselinu kao standard. Biološka aktivnost ekstrakata ispitana je na miševima koji su hranjeni sirovim ekstraktom u dozama od 30, 100 i 300 mg/kg. Ispitani su sljedeći parametri: mehanička hiperalgezija pomoću von Frey filamenata, toplinska hiperalgezija na vrućoj ploči pri 55 °C, edem šape pomoću pomičnog mjerila i aktivnost mijeloperoksidaze kao pokazatelj aktivacije neutrofila. Nefrotoksičnost i hepatotoksičnost su ispitane biokemijskim pretragama uzoraka krvi miševa hranjenih ekstraktom grožđa vrste Vitis labrusca. Rezultati i zaključci. Maseni udjel pokožica u svim uzorcima otpada vinske industrije iznosio je 75 % mokre tvari i 59 % suhe tvari. Identificirali smo devet različitih antocijanina (3-O-glukozide peonidin, delfinidin, petunidin i malvidin; 3-p-kumaroil-glukozide cijanidin, peonidin, pe¬tunidin i malvidin, te malvidin-3,5-diglukozid), pet flavonoida (apigenin-7-glukozid, luteolin-7-glukozid, kvercetin-3-galaktozid, izorhamnetin-3-glukozid i miri¬cetin-3-rutinozid), a maseni udjel fenolnih spojeva, izražen kao ekvivalent galne kiseline, bio je 26,62 mg/g. Ispitivanja in vivo pokazala su da su ektrakti grožđa vrste Vitis labrusca masenog udjela 100 i 300 mg/kg smanjili mehaničku |
