Direct measurement of total antioxidant capacity of cereals: QUENCHER-CUPRAC method

Talanta, 2013
Polyphenols in cereal samples are distributed as free, soluble-esterified, and insoluble-bound forms either esterified or etherified to cell wall constituents. In the evaluation of total antioxidant capacity (TAC) of cereals, rather difficult and time-consuming acid, alkaline and enzymatic treatments of residue have been applied to complete the ...

Heparin-stabilized gold nanoparticles-based CUPRAC colorimetric sensor for antioxidant capacity measurement

Talanta, 2018
Sensing of total antioxidant capacity (TAC) as an integrated parameter showing the collective action of various antioxidants is an important challenge in food, biochemical and drug analysis. A novel heparin-stabilized gold nanoparticles (AuNPs)-based 'cupric reducing antioxidant capacity' (CUPRAC) colorimetric sensor was designed for TAC measurement ...

A new colorimetric method for CUPRAC assay with using of TLC plate

LWT - Food Science and Technology, 2019
Abstract Cupric reducing antioxidant capacity (CUPRAC) method is one of the most widely used antioxidant methods. However, its need for a spectrophotometer, as in many other methods, is an important disadvantage. Cupric reducing antioxidant capacity was determined based on color analysis with Image J program in computer with the new method developed ...

Development of an Electrochemical Cupric Reducing Antioxidant Capacity Method (CUPRAC) for Antioxidant Analysis

Electrochimica Acta, 2014
Abstract Cupric Reducing Antioxidant Capacity method, CUPRAC, is a reliable assay for determining Total Antioxidant Capacity (TAC) in samples of foods, beverages and pharmaceutical formulations. In this work, an electrochemical approach was used to quantify antioxidant content employing a variation of the CUPRAC assay, as the concentrations of the ...

Combined HPLC-CUPRAC (cupric ion reducing antioxidant capacity) assay of parsley, celery leaves, and nettle

Talanta, 2008
This study aims to identify the essential antioxidant compounds present in parsley (Petroselinum sativum) and celery (Apium graveolens) leaves belonging to the Umbelliferae (Apiaceae) family, and in stinging nettle (Urtica dioica) belonging to Urticaceae family, to measure the total antioxidant capacity (TAC) of these compounds with CUPRAC (cupric ion ...
