Divicine

Divicine (2,6-diamino-4,5-dihydroxypyrimidine) is an oxidant and a base with alkaloidal properties found in fava beans and Lathyrus sativus. It is an aglycone of vicine. A common derivative is the diacetate form (2,6-diamino-1,6-dihydro-4,5-pyrimidinedione). Divicine (2,6-diamino-4,5-dihydroxypyrimidine) is an oxidant and a base with alkaloidal properties found in fava beans and Lathyrus sativus. It is an aglycone of vicine. A common derivative is the diacetate form (2,6-diamino-1,6-dihydro-4,5-pyrimidinedione). Divicine is found in fava beans and in the legume Lathyrus sativus, also known as khesari, which is a cheap and robust food source commonly grown in Asia and East Africa. In plants, reduced divicine is formed from the hydrolysis of the inactive β–glucoside, vicine.
