Furthermore, anthocyanins are known to have vital physiological functions in plants owing to their antioxidant effect; MPO and NO are known sources of free radicals and can induce the reduction of ferritin (Fe3+) to free Fe2+, contributing to oxidative damage [15, 16]; both these components also play a very important role in the pathogenesis of IBD [17, 18]. This evidence concerns the gene MPO and inflammatory bowel disease.
