The present review focuses on electrochemical methods for ascorbic acid assessment. The
occurence, role, biological importance of vitamin C, as well as the non-electrochemical …

A switchable sensor based on N and S co-doped carbon dots (N, S-CDs) was developed to
determine ascorbic acid (AA) content in common fruits via fluorescence quenching of N, S …

The chemical diversity of antioxidants makes it difficult to separate and quantify antioxidants
from the vegetable matrix. Therefore, it is desirable to establish a method that can measure …

Ascorbic acid (AA) is a water-soluble vitamin essential in the human nutrition, an antioxidant,
a scavenger of free radicals in biological systems and a cofactor of several enzymes. For the …

In the present study, an ecofriendly and zero-cost approach has been demonstrated for the
preparation of carbon quantum dots by one-pot hydrothermal treatment of leaf extracts of …

A fast and simple voltammetric method based on the use of ZrO 2 nanoparticle/ionic liquids
carbon paste electrode (ZrO 2/NPs/IL/CPE) is proposed for the determination of vitamin C …

Background: Tests measuring the combined antioxidant effect of the nonenzymatic defenses
in biological fluids may be useful in providing an index of the organism's capability to …

The chemical diversity of antioxidants in complex matrices such as plant extracts makes it
difficult to separate and quantify antioxidants from these solutions. Therefore it is desirable to …

Vitamin C is a water-soluble compound found in living organisms. It is an essential nutrient
for various metabolism in our body and also serves as a reagent for the preparation of many …

In this study, a simple and rapid analytical method development for ascorbic acid (AA)
determination in food samples by using differential pulse voltammetry (DPV) method on …
