Background: Tests measuring the combined antioxidant effect of nonenzymatic defenses in biological fluids may be useful providing an index organism's capability to counteract reactive species known as prooxidants, resist oxidative damage and combat stress-related diseases. The selected chromogenic redox reagent for assay human serum should easily accessible, stable, selective, respond all types biologically important antioxidants such ascorbic acid, α-tocopherol, β-carotene, reduced...
Summary Apricots as five varieties of Malatya region have been assayed fresh, sun‐ and sulphited‐dried samples, using the antioxidant capacity measurement methods Cupric Ion Reducing Antioxidant Capacity (CUPRAC) 2,2′‐azinobis (3‐ethylbenzothiazoline‐6‐sulphonic acid) (ABTS), total polyphenol method Folin. The novel reagent for CUPRAC assay, bis (neocuproine)copper(II) chloride, was easily accessible, stable, selective responding to all antioxidants. Sulphite (normally contributing colour...
This study aims to investigate the total antioxidant capacity (TAC) as trolox equivalent (mmol g-1) of nineteen edible wild plants traditionally used in Ayvalik using four different assays, CUPRAC, ABTS, FRAP and Folin. The order ten exhibiting higher capacities could be listed as: Daucus carota (1st wrt FRAP), Sonchus oleraceus (2nd asper (3rd), Rumex pulcher (4th Folin), Cichorium intybus (5th Papaver rhoeas (7th Foeniculum vulgare (8th CUPRAC Urtica pilulifera (6th 8th acetosella Folin,...
Medicinal plants, especially rich in polyphenolic compounds, have been suggested to be chemopreventive on account of antioxidative properties. Salvia officinalis L., an aromatic and medicinal plant, is widely used folk medicine well known for its antioxidant Therefore, the present study was designed investigate antioxidative, possible genotoxic, antigenotoxic potency S. extract against cyclophosphamide (CYP)-induced oxidative stress genotoxicity Wistar albino rats. Animals were orally dosed...
The traditional Van herby cheese incorporates herbs mainly consisting of Allium species as antimicrobial and flavouring aids. total antioxidant capacities 16 different (8 species) collected from locations were assayed for the first time by CUPRAC, ABTS/persulfate, FRAP, Folin methods. assay results correlated well among each other, because all electron-transfer assays. highest obtained with having redox potential. second especially allium sp., sulfur containing antioxidants in could be best...
ABSTRACT Hazelnut (Corylus avellana L.) has an important nutritional value comprising a rich variety monounsaturated fats and vitamins, with good level of dietary fiber high content minerals. In the present work, phenolics in aqueous systems were extracted from 15 different dry Turkish hazelnut kernels without skin, cultivated Ordu province Turkey, 80% (v/v) MeOH/H2O. The methanolic extracts oil samples examined for their phenolic contents (Folin-Ciocalteau), total antioxidant capacities...
Abstract The essential oil compositions of aerial parts Salvia macroclamys, S. verticillata ssp. amasiaca, virgata, multicaulis, firigida, microstegia and kronenburgii were analyzed by gas Chromatography-mass spectrometry (GC-MS). Their main constituents found to be α-pinene, β-pinene, 1,8-cineole, Thymol, caryophyllene oxide. kronenburgii, the pure compounds linalool oxide tested against E. coli, aureus, K. pneumonia, yeast C.albicans.
The chemical composition of fatty acid methyl esters (FAMEs) from seeds S. thymbra and cuneifolia were analyzed by GC/MS. 7 FAMEs identified the mainly as 9-octadecenoic ester (43.9%), hexadecanoic (11.4%), 9,12,15-octadecatrienoic (Z,Z,Z) (30.2%), octadecanoic (14.1%), while seed 10 obtained with main components, similar to thymbra. These (10.1%), (methyl palmitate, 34.6%), (6.3%) (1.8%).
The effect of microwave-assisted extraction (MAE) process on the antioxidant capacity/activity three medicinal herbs from Turkey was investigated by electrochemical differential pulse voltammetric (DPV)-CUPric Reducing Antioxidant Capacity (CUPRAC) assay.The optimal time, temperature and solvent type were 6 min, 80 °C 80% (v/v) methanol (MeOH), respectively.Microwave-assisted extracts (Hypericum scabrum L., Papaver fugax Poiret var.platydiscus Cullen, Achillea vermicularis Trin.) screened...
Abstract essential oils of aerial parts the Satureja cuneifolia were extracted by simultaneous distilation-exraction and analyzed gas Chromatography-mass spectrometry (GC-MS). Thymol was determined as main component, comprising 35.8% oil. The other important compounds found to be p-cymene (18.3%), y-terpinene (14.2%), p-cymene-2,5-dione (4.5%), carvacrol (3.6%), β-myrcene (3.0%) ot-terpinene (2.3%). In total, 30 oil identified from cuneifolia, which harvested Çanakkale-Kilitbahir Region,...
Background: Glutathione peroxidase (GSH-Px) is one of the major enzyme in antioxidative defense mechanism present cells. Methods: In study a novel and simple microplate-based method was developed, using cupric neocuproine complex (Cu(Nc)2 2+) as chromogenic oxidizing reagent, for assessment GSH-Px activity biological samples first time. this measurement, catalyzed oxidation Reduced (GSH) gives rise to oxidized form GSH (GSSG). The recommended based on reduction Cu(Nc)2 2+ highly colored...
The aim of this study is to examine the effect Tabata Training Program (TAP), which has been applied for 6 weeks, on some physical and motoric characteristics female volleyball player players participated in voluntarily 11 females (age = 15,27 ± 1,10 years, height 170,27 6,00 cm body weight 63,36 6,96 kg) high school team. In study, pretest-posttest experimental method was used. training a type High Intensity Interval (HITT) aims develop aerobic anaerobic capacity sports. athletes were given...
There is a current research tendency towards the biodegradable thermoplastic materials from renewable resources since environmental restraints play vital role in recent years.Starch one of and abundantly available form plant products.It possible to blend starch with various achieve such aims.In this study, an ethylene-vinyl acetate (EVA) copolymer resin (Luvax 40 W, DuPont) was blended modied (Maize Starch, Pendik Nisasta) amounts by means single screw extruder dierent speeds.For purpose,...
