BACKGROUND The aim of the current investigation was to identify bioactive secondary metabolites including phenols, tannins, flavonoids, terpinedes, and steroids and compare the phytochemical analysis and antioxidant profile of the juice extracted from the fruits of Citrus sinensis, Citrus anrantifolia, and Citrus limonum. RESULTS Phytochemical screening is important for the isolation of new, ...

The aim of this study was to assess the ability of different wines – a sweet red, a dry red, a sweet white, and a dry white – to scavenge the stable 1,1’-diphenyl-2-picryl-hydrazyl radical (DPPH.) and to determine their phenolic composition. Both red wines contained, apart from anthocyanins, also higher concentration of total phenolics, tartaric esters, and flavonols than the two white wines. A...

Phenolic compounds are present at very high concentrations in the bark of Acacia mangium. These compounds are known to have strong antioxidant activity and thus different beneficial effects on human health. Phenolic compounds in bark of A. mangium were extracted and their antioxidant activities were investigated using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical-scavenging and ferric-r...

The influence of the addition 2.5, 5, 7.5, and 10.0% dried Enoki Maitake mushrooms on content bioactive compounds some nutraceutical properties pasta was determined in study. LC-MS/MS analysis phenolic revealed highest amount Maitake-supplemented pasta. However, all samples Enoki-enriched exhibited a statistically significantly higher α-glucans than control. Samples subjected to gastrointestina...

Six medicinal plants Helichrysum italicum (Roth) G. Don, Angelica archangelica L., Lavandula officinalis L., Salvia officinalis L., Melilotus officinalis L., and Ruta graveolens L. were used. The aim of the study was to compare their extracts obtained by Soxhlet (hexane) extraction, maceration with ethanol (EtOH), and supercritical CO2 extraction (SC-CO2) targeted on coumarin content (by high p...

The present study is focused on anthocyanin derivatives characterizing the antioxidant activity of Cabernet Sauvignon wines produced from different vineyard regions in the Balkans. These bioactive compounds were quantified with a high performance liquid chromatography (HPLC)-diode array detection (DAD) method. The antiradical activity was estimated by the ability of the wine to scavenge the sta...

Two samples of oak honeydew honey were investigated. Headspace solid-phase microextraction (HS-SPME) combined with GC and GC/MS enabled identification of the most volatile organic headspace compounds being dominated by terpenes(mainly cis- and trans-linalool oxides). The volatile and less-volatile organic composition of the samples was obtained by ultrasonic assisted extraction (USE) with two s...

Abstract The kinetic characteristics, mechanisms of activity, and relationship between the antioxidant activity molecular supramolecular structure fullerene C 60 some its N -monosubstituted amino acid derivatives have been studied. introduction an substituent in molecule led to increase antiradical free radical oxidation a water-soluble target (fluorescein). mechanism is not associated with hyd...

Most potato proteins are fractions of albumin and globulin, soluble in water salt solutions, respectively; these patatin glycoproteins, with a pIs the range 4.8–5.2. This group is typical they referred to as or tuberin. Around 30–50% comprise numerous protease inhibitors molecular weight 7–21 kDa; often heat-resistant, showing wide spectrum health-promoting effects. The nutritional value relate...

The paper presents results of the comparative study iron-chelating potential and antioxidant activity raw material phytopreparations analysis correlations between these activities content phenolic compounds as most important plant antioxidants. total was determined by Folin-Chokalteu method, che-lating evaluated using ferrozine antiradical DPPH assay, (reducing) capacity assessed phosphomolybde...
