摘要
Several flavones and flavonols (chrysin, quercetin, luteolin, flavone and 7, 8-benzoflavone) were found to inhibit ethoxyresorufin deethylase (EROD) activity in human and rat liver microsomes. In man, molecules without hydroxyl groups are more powerful inhibitors than polyhydroxylated flavonoids (7, 8-benzoflavone > flavone > chrysin > luteolin > quercetin > morin). In rat, chrysin was the strongest inhibitor and the less effective were morin and 7, 8-benzoflavone. For all molecules human microsomes were more sensitive than rat microsomes. The most important difference concerned 7, 8-benzoflavone which was 10 000-fold more potent in man. © 1990 Taylor & Francis Ltd.
