Abstract

The antimutagenic effects of apple enzymatic browning reaction products(AEBRP) which resulted from the reaction of catechol, hydroquinone, homocatechol, hydroxyhydroquinone and pyrogallol with polyphenol oxidase extracted from apple(Jona gold) were investigated. Test strain used in SOS spot test and SOS chromotest was E. coli PQ 37/plasmid pKM 101. In SOS spot test, all of five AEBRPs showed strong antimutagenic effects on mytomycin C(MMC), 4-nitroquinoline-1-oxide(4NQO), N-me-thyl-N'-nitro-N-nitrosoguanidlne(MNNG) as increasing concentrations of AEBRP solution. In SOS chromotest, most of AEBRPs also showed strong antimutagenic effects on MMC, MNNG, 4NQO and 3-amino-1,4-dimethyl-5H-pyrido(4,3-b)indole (Trp-P-1), as increasing concentration of AEBRP solution.

사과(Jona gold)로부터 추출한 polyphenol oxidase와 polyphenol 화합물인 catechol, hydroquinone, homocatechol, hydroxyhydroquinone 그리고 pyrogallol 용액과 반응시켜 얻어진 사과효소 갈변반응 생성물에 대한 항돌연변이원성 효과를 검토하였다. SOS spot test와 SOS chromotest에 사용된 균주는 E. coli PQ37/plasmid pKM101 균주이며 spot test에서 위 다섯 종류의 시료 모두 갈변용액의 농도를 증가시켜 줌에 따라서 mitomycin C(MMC), 4-nitroquinoline-1-oxide(4NQO), 그리고 N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) 등의 발암물질들에 대해서 강한 억제활성을 나타내었다. 한편, SOS chromotest에서도 발암물질의 종류에 따라 차이는 있으나 갈변용액의 농도증가에 따라 MMC, MNNG, 4 NQO 그리고 3-amino-1,4-dimethyl-5H-pyrido-(4,3-b) indol (Trp-P-1) 등에 대해서 강한 억제활성을 나타내었다.
