Two major betalains, red-purple betacyanins and yellow betaxanthins, were isolated from red beetroots (Beta vulgaris L.), and their peroxynitrite (ONOO(-)) scavenging capacity was investigated. Apparent colours of the betalains were bleached by the addition of ONOO(-), and the absorbance decreases were suppressed in the presence of glutathione, a ONOO… CONTINUE READING
