In the present report the changes in mussels Mytilus galloprovincialis protein profile, as a reaction of water pollution, is presented. The antioxidant capacity was determined by the efficacy to scavenge the derived radical in mussel samples using the Trolox Equivalent Antioxidant Capacity (TEAC) assay. The highest percentage of inhibition was estimated in protein mussels from the dirty area (D...

Jatropha curcas L. protein hydrolysates were produced by treatment of a non-toxic genotype with Alcalase as well as the digestive enzymes pepsin and pancreatin. The J. curcas protein hydrolysate produced with the pepsin-pancreatin system from protein isolate had the highest TEAC value and was shown to undergo single-electron transfer reactions in the ABTS(+) reduction assay, demonstrating its a...

Purpose: To evaluate the effects of intraluminal injection of glutamine on the serum trolox equivalent antioxidant capacity in an experimental model of ischemia-reperfusion of the liver observing the applicability of modifications on the original assay method. Methods: Thirty Wistar rats underwent laparotomy to perform a 20 cm blind sac of small bowel and occlusion of the hepatic hilo for 30 mi...

Bu çalışmada Türkiye’de yetiştirilmiş Citrus maxima (Şadok) meyvesinin gıda tüketim atığı olarak nitelendirilebilecek dış kabuk ve albedo kısmının antioksidan, fenolik flavonoid madde miktarlarının belirlenmesi amaçlanmıştır. Meyve kısmından ayrılan atık parçalar kurutularak etanol, metanol saf su ile ekstrakte edilmiştir. Dış ekstrelerinden elde edilen sonuçlara göre için en yüksek değer 59.64...

Abstract In this study, samples of mandarin-like hybrids (Clemenvilla, Nadorcott and Ortanique) from two harvesting seasons (2017−2018 2018−2019) were analyzed, to evaluate its differences in physicochemical characteristics nutritional properties establish the parameters that allow classify these citrus cultivars. Results showed Clemenvilla juice had highest concentration total phenolic ascorbi...

Novel anthraquinone-based cyclic antioxidants containing amino, thio and oxo groups were synthesized their antioxidant capacity was determined by using the cerium(IV)-reducing (CERAC) assay. 1H, 13C NMR, FTIR-spectroscopy ESI (Electrospray Ionization) mass spectrometry used for characterization of anthraquinone derivatives exhibiting CERAC capacity. This study is great importance, because compo...

The anti-oxidant activities for a diverse set of flavonoids as TEAC (Trolox equivalent anti-oxidant capacity), assay were subjected to 3D-QSAR (3 dimensional quantitative structural-activity relationship) studies using CoMFA (comparative molecular field analysis) and CoMSIA (comparative molecular similarity indices analysis). The obtained results indicated superiority of CoMSIA model over CoMFA...

The antioxidant capacity of 80% methanolic extracts from stems, leaves, flowers and mature seeds of common and tartary buckwheat during growth period was determined against ABTS·+ (TEAC assay) and O2 radicals (PCL assay). The antioxidant capacity of aerial parts of buckwheat was highly differentiate during growth period. The highest antioxidant capacity was noted in flowers of common buckwheat ...

The biomass components of the invasive seaweed Sargassum muticum were fractionated to allow their separate valorization. S. muticum (Sm) and the solid residue remaining after alginate extraction of this seaweed (AESm) were processed with hot, compressed water (hydrothermal processing) to assess the effects of temperature on fucoidan solubilization. Fucose-containing oligosaccharides were identi...

The underutilized fruits Baccaurea ramiflora (Kusum) from the eastern region of India were investigated for nutritional composition, phytochemicals and bioactive compounds. A detailed nutritional characterization of the fruit demonstrated that it has the potential to act as good source of minerals along with other nutrients, dietary fibres, significant phenolic compounds and possesses antioxida...
