Glossary: ferruginol = abieta-8,11,13-trien-12-ol

Other name(s): CYP76AH24; CYP76AH3

Systematic name: ferruginol,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (11-hydroxyferruginol forming)

Comments: A cytochrome P-450 (heme-thiolate) protein isolated from the plants Salvia pomifera (apple sage) and Salvia miltiorrhiza (danshen). 11-Hydroxyferruginol is a precursor of carnosic acid, a potent antioxidant.
