HPLC Determination of Monoamines in Rat Brain after Enzymatic Treatment with Ascorbate Oxidase and Sulfatase

Abstract

The simultaneous analysis of norepinephrine, dopamine and serotonin along with their respective metabolites, MHPG, DOPAC and 5HIAA is accomplished in rat brain by using a recently developed HPLC technique. Sulfated MHPG is decongegated with sulfatase for detection purposes and endogenous ascorbate is diminished with ascorbate oxidase to reduce the front.
