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.
