Comparative 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… Expand
Determination of total antioxidant capacity by a new spectrophotometric method based on Ce(IV) reducing capacity measurement.
Dietary antioxidants widely found in fruits and vegetables may serve the task of reducing oxidative damage in humans induced by free radicals and reactive oxygen species under 'oxidative stress'… Expand
Modified cerium(IV)-based antioxidant capacity (CERAC) assay with selectivity over citric acid and simple sugars
Abstract A Ce(IV)-based reducing capacity (CERAC) assay was developed to measure the total antioxidant capacity (TAC) of foods, in which Ce(IV) would selectively oxidize antioxidant compounds but not… Expand
Determination of Total Antioxidant Capacity by a New Spectrofluorometric Method Based on Ce(IV) Reduction: Ce(III) Fluorescence Probe for CERAC Assay
A Ce(IV)-based reducing capacity (CERAC) assay was developed to measure the total antioxidant capacity (TAC) of foods, in which Ce(IV) would selectively oxidize antioxidant compounds but not citric… Expand

The Folin-Ciocalteu (FC) method of performing a total phenolics assay, originally developed for protein determination, has recently evolved as a total antioxidant capacity assay but was found to be… Expand
ADJOINT CODE BY SOURCE TRANSFORMATION WITH OPENAD/F
This document reports on recent advances in the development of the adjoint code generator OpenAD/F. We give an overview of the software design, and we discuss case studies that illustrate the… Expand
Genotoxic, cytotoxic, and apoptotic effects of Hypogymnia physodes (L.) Nyl. on breast cancer cells
The aim of this study is to determine the chemical composition, and evaluate the genotoxic, and anti‐growth potency of the methanol extracts of lichen species Hypogymnia physodes (L.) Nyl. (HPE).… Expand

BACKGROUND This study proposes modifications to the conventional Folin-Ciocalteu (FC) spectrophotometric method for individually determining ascorbic acid (AA) in complex matrices in the presence of… Expand
Determination of Tetracycline on the Surface of a High- Performance Graphene Modified Screen-Printed Carbon Electrode in Milk and Honey Samples
Nanoceria-based reactive species scavenging activity of antioxidants using N,N-dimethyl-p-phenylenediamine (DMPD) probe
The aim of this work was to develop a fast and low-cost method to measure the reactive species formed in an aqueous suspension utilizing nanoceria as a peroxidase-like catalyst. Nanoceria was… Expand
