Abstract

The antimutagenic effects of 27 kinds of plant flavonoids on the mutagenicity of aflatoxin $B_1(AFB_1)$ and N-methyl-N'-nitro-N-nitrosoguanidine(MANG) in Salmonella typhimurium TA 100 were investigated. In the mixed applications of $AFB_1\;(1\;\mu{g/plate)}$ with the flavonoids $(300\;\mu{g/plate)}$ in the presence of a mammalian metabolic activation system (S9 mix), chrysin, apigenin, luteolin and its glucoside, kaempferol, fisetin, morin, naringenin, hesperetin, persicogenin, (+)-catechin and (-)epicatechin showed the antimutagenic effect against $AFB_1$ with more than 70% inhibition rate. A little or no antimutagenicities except flavone against MNNG $(0.5\;\mu{g/plate)}$ were observed. For the antimutagencity of the flavonoids on $AFB_1$, the flavonoid structure that contains the free 5, 7-hydroxyl gorup seemed to be essential. However, saturation of the 2, 3-double bond of elimination of the 4-keto group did not affect the activity.
