Vicine, an alkaloid glycoside found mainly in fava beans, is toxic in individuals who have a hereditary loss of the enzyme glucose-6-phosphate dehydrogenase and may cause haemolytic anaemia.Vicine is an inactive compound that is hydrolysed by the intestinal microflora to a highly reactive free radical generating compound, the aglycone divicine when Vicine enters the body through food[1][2][3][4].
