Abstract

The methanol extract of perilla leaves contained compounds to reduce the mutagenicity of aflatoxin B$_1$(AFB$_1$) in Salmonella typhimurium TA98 and 100. They were separated by solvent extractions and identified by GC and GC-MS as 2-ethoxy acetate, 1, 2, 3, 4-tetramethyl-cis-cyclobutene, two isomers of methyl 11, 14, 17-eicosatrienoate, 12-acetyl-9-octadecanoic acid, and phytol. The antimutagenicities of phytol and methyl 11, 14, 17-eicosatrienoate were dependent on the mutagens tested. Phytol reduced the mutagenicity of Trp-p-2 but not of AFB$_1$and methyl 11, 14, 17-eicosatrienoate reduced the activities both of the mutagens.

들깻잎의 메탄을 추출물이 S. typhimurium TA98과 100에서 aflatoxin B$_1$(AFB$_1$)의 돌연변이 유발성을 억제시키는 효과가 있었다. 메탄을 추출물을 silica gel column을 사용하여 더욱 분획하여 항돌연변이 효과를 시험하였으며, 그중 효과가 가장 컸던 fraction 중의 화합물을 분리, 동정한 결과 2-ethoxy acetate, 1, 2, 3, 4-tetramethyl-cis-cyclobutene, 두 개의 methyl 11, 14, 17-eicosatrienoate 이성체, 12-acetyl-9-octadecanoic acid, 그리고 Phytol이 있음이 잠정적으로 밝혀졌다. Phytol과 methyill, 14, 17-eicosatrienoate의 표준품을 사용하여 AFB$_1$및 Trp-P-2에 대한 항돌연변이 효과를 시험한 결과 그 효과가 컸음이 밝혀졌다.
