This study was performed to determine the effects of antimutagenicity of Porturaca oleracea L. in Korea. In Ames test, the ethanol extract of Poturaca oleracea L. inhibited mutagenic activity of N-methyl-N'-nitro-N-nitrosoguanidine(MNNG), , 4-nitroquinoline-1-oxide(4NQO), benzo($\alpha$)pyrene (B($\alpha$)P) and 3-amino-1,4-dimethyl-5H-pyrido-(4,3-b)indole (Trp-P-1) in Salmonella typhimurium TA98 and TA100. But hot-water extract Poturaca oleracea L. only Inhibited mutagenic activity of MNNG in Salmonella typhimurium TA100, On 4NQO, the ethanol extract 100-1,600$\mu\textrm{g}$/plate of Porturaca oleracea L. showed a slight inhibitory effect of 13-48%, 4-47% in TA98 and TA100, respectively, but on MNNG, it showed higher inhibitory effect of 6-86% in TA100, And the treatment of 1,600$\mu\textrm{g}$/plate of ethanol extract of Porturacea L. had strong antimutagenicity with 74-87% inhibition against TA98 and TA100 induced by B(a)P and with 85-93% inhibition against TA98 and TA100 induced by Trp-P-1. The ethanol extract was fractionated with ether. chloroform, ethylacetate, butanol and water. Among them, most of the fraction except water fraction showed strong antimutagenicity effects against mutation induced by 4-NQO, MNNG, B(a)P and Trp-P-1. Chloroform fraction had strong antimutagenicity with 91% inhibition against TA100 induced by MNNG, diethyl etherfraction had strong antimutagenicity with 92%, 98% inhibition against TA98 and TA100 induced by 4NQO, Chloroform fraction had strong antimutagenicity with 97% inhibition against TA100 induced by B (a)P and diethyl etherfraction had strong antimutagenicity with 98% inhibition against both strain Induced by Trp-P-1, respectively.
