متن کاملA comparison of ABTS and DPPH methods for assessing the total antioxidant capacity of human milk.
INTRODUCTION The Total Antioxidant Capacity (TAC) of human milk reflects the concentration and the activity of many components which prevent oxidative degradation of fats and proteins. This study compares the effectiveness of ABTS and DPPH tests with regard to the recovery, precision and sensitivity (detection and quantification limit) of (TAC) values in human milk. MATERIAL AND METHODS TAC v...
متن کاملComparison of Prooxidant-antioxidant Balance Method with Crocin Method for Determination of Total Prooxidant-antioxidant Capacity
Objective(s) Comparison of prooxidant-antioxidant balance (PAB) assay with crocin assay. Materials and Methods Twenty eight serum samples were chosen, PAB and the total antioxidant capacity were measured by PAB assay and crocin, respectively, and the correlation of both assays, along with their correlation with other clinical and biochemical parameters, were determined. Results A significa...
متن کاملComparative evaluation of various total antioxidant capacity assays applied to phenolic compounds with the CUPRAC assay.
It would be desirable to establish and standardize methods that can measure the total antioxidant capacity level directly from vegetable extracts containing phenolics. Antioxidant capacity assays may be broadly classified as electron transfer (ET)- and hydrogen atom transfer (HAT)-based assays. The majority of HAT assays are kinetics-based, and involve a competitive reaction scheme in which ant...
متن کاملA flow injection biamperometric method for determination of total antioxidant capacity of alcoholic beverages using bienzymatically produced ABTS
Development of flow injection analysis (FIA) is reported for determination of total antioxidant capacity of alcoholic beverages (wines and spirits) by bienzymatically produced ABTS + and electrochemical detector using interdigitated gold electrode (IDE). The method is based on biamperometric measurements using ABTS jABTS redox couple. During the analysis, ABTS radical cation was bienzymatically...
