Dihydrobenzophenanthridine oxidase (DHBP oxidase) is an enzyme. In the IUBMB Enzyme Nomenclature, dihydrobenzophenanthridine oxidase is .
Dihydrobenzophenanthridine oxidase produces oxidized forms of benzophenanthridine alkaloids: In Sanguinaria canadensis (bloodroot), dihydrobenzophenanthridine oxidase produces sanguinarine from dihydrosanguinarine, and chelirubine from dihydrochelirubine.
In Eschscholzia californica (California poppy), dihydrobenzophenanthridine oxidase produces macarpine from dihydromacarpine.
