Cytochrome P450 (P450)-dependent p-hydroxylation of aniline and o-deethylation of 7-ethoxycoumarin were examined in rat liver microsomes in the presence of radical scavengers. The addition of beta-carotene, a quencher of singlet oxygen species ((1)O(2)), suppressed the aniline hydroxylation, while the addition
