objective: the role of herbs against the free radicals have been put forth recently in combating many diseases. the aim of this study was to elucidate the in vitro capacity and in vivo antioxidant properties of sedimental extract of tinospora cordifolia (setc). materials and methods: setcwas subjected to in vitro chemical analysis such as 1,1-diphenyl-2-picrylhydrazyl (dpph), nitric oxide, hydr...

Coumarins are secondary metabolites that are widely distributed within the plant kingdom, some of which have been extensively studied for their antioxidant properties. The antioxidant activity of coumarins assayed in the present study was measured by different methods, namely the 1,1-diphenyl-2-picryl-hydrazyl (DPPH(•)) method, cyclic voltammetry and the antioxidant capacity against peroxyl rad...

the objective of this study was to produce fish protein hydrolysate (fph) with the most antioxidant activity, by enzymatic hydrolysis from (carassius carassius). the protein of crucian carp a low value fish was hydrolyzed by alcalase 2.4l and the optimal hydrolysis parameters of strongest antioxidant capacity of peptides were obtained using response surface methodology (rsm) by the central rota...

BACKGROUND/OBJECTIVES The objective of this study was to measure and/or estimate the total antioxidant capacity of the Korean diet. MATERIALS/METHODS Eighty-one plant foods that were expected to exhibit rather high antioxidant activities were selected from the Korean diet using the Fifth Korean National Health and Nutrition Survey (KNHANES V). These foods were categorized into 11 food groups:...

Objective. Total antioxidant capacity in serum is determined by the total mass of antioxidant substances and the antioxidant capacity per unit mass (average activity). The purpose of this study was to develop a method to determine the mass of antioxidant substances and average activity in human serum. Methods. Specimens of serum were collected from 100 subjects each from two different age group...

Determination of the relative contribution of uric acid level increases to the total measured antioxidative activity could be very useful for testing antioxidative products and their effect on human health. The aim of this report is to present a simple spectrophotometric method that combines the measurement of total antioxidative capacity of a sample by ferric reducing/antioxidative power (FRAP...
