Dihydrobenzophenanthridine oxidase (DHBP oxidase) is an enzyme. In the IUBMB Enzyme Nomenclature, Dihydrobenzophenanthridine oxidase is EC 1.5.3.12. Dihydrobenzophenanthridine oxidase/EC 1.5.3.12 produces oxidized forms of benzophenanthridine alkaloids:

• In Sanguinaria Canadensis EC 1.5.3.12 produces sanguinarine from dihydrosanguinarine, and chelirubine from dihydrochelirubine.
• In California poppy, EC 1.5.3.12 produces macarpine from dihydromacarpine.
