Abstract:
... Amaranth is presently an underutilized crop despite its high content of micronutrients/bioactive phytochemicals and its capacity to thrive in harsh environmental condition. The present study aimed at determining the health benefits of Amaranthus cruentus L. in terms of protection against DNA damage induced by the mycotoxin aflatoxin B1 (AFB1) and oxidative stress using comet assay. The antioxidant ...

Abstract:
... BACKGROUND AND AIMS: Stilbenes are an important group of phenolic substances that exist in roots, stems, leaves, skins and seeds. But little work has been performed to characterise the composition of grape root or to measure the antioxidant capacity of several stilbenes with hydroxyl radicals,1,1‐diphenyl‐2‐picrylhydrazyl and nitric oxide free radicals. METHODS AND RESULTS: Stilbenes were analysed ...
