A simple, rapid, and accurate method for determination of selenocystine (SeCys 2 ), methyl selenocysteine (MeSeCys), selenourea (SeUr), selenite (Se(IV)), selenotmethionine (SeMet), and selenate (Se(VI)) in grain crops was developed, based on the coupling of ion-pair reversed-phase high-performance...
