There is a vast research literature on the antioxidant activity in food. [...].

Although the term 'antioxidant' is used very frequently, there are problems with the definition of antioxidants and estimation of antioxidant activity. The distinction between antioxidant and antiradical activities is not always obvious. This minireview discusses critically the principles, advantages and limitations of the most frequently used methods of estimation of antiradical and antioxidan...

Antioxidant activity has been assessed in many ways. The limitation of many newer methods is the frequent lack of an actual substrate in the procedure. The combination of all approaches with the many test methods available explains the large variety of ways in which results of antioxidant testing are reported. The measurement of antioxidant activities, especially of antioxidants that are mixtur...

background: there are studies that indicated dyshomeostasis of oxidant/antioxidant and trace elements in breast cancer patients, but the data regarding the status of these parameters in various stages of breast cancer are limited. the aim of this study was to highlight the status of these biochemical factors in various stages of breast cancer. methods: fifty-eight breast cancers patients partic...

The assessment of interactions between natural antioxidants and other food matrix components represents the main step in the investigation of total antioxidant properties, in terms of potential health benefits. The diversity of chemical structures of natural compounds, besides their possible interactions, as well as the biological role and different modes of action makes it difficult to assess ...

A variety of sulfonamidomethane linked 1,3,4-oxadiazoles and 1,3,4-thiadiazoles were prepared and tested for antioxidant activity. The methyl substituted arylsulfonylaminomethyl-1,3,4-oxadiazole 9b showed excellent antioxidant activity.
