title: High-pressure liquid chromatographic separation of 10 benzo(a)pyrene phenols and the identification of 1-phenol and 7-phenol as new metabolites.
abstract: The separation of ten isomeric benzo(a)pyrene phenols has been accomplished by the use of high-pressure liquid chromatography utilizing a newly developed recycling technique and new column and solvent systems. Using this new system and comparing the metabolites obtained with authentic standards, we have isolated 1-hydroxybenzo(a)pyrene and 7-hydroxybenzo(a)pyrene and identified them as metabolites formed by rat liver microsomes. In previously reported chromatography systems, the new metabolites migrated with another metabolite, 3-hydroxybenzo(a)pyrene.
