초록

고구마효소 갈변반응생성물(SPEBRP)의 항돌연변이 효과를 검토하기 위하여 DNA breaking test, spore rec assay, Ames test를 행하였다. DNA breaking test에서 catechol- 및 hydroxyhydroquinone-SPEB-RPs는 $Fe^{2+}$ 존재하에서 DNA breaking effect를 저해하였다. Bacillus subtilis H17(rec+) 및 M45(rec-)를 이용한 spore rec assay엣 3,4-dihydroxytoluene-SPEBRP는 MNNG에 대하여 강한 돌연변이 효과를 나타내었다. Salmonella typhimurium TA98 및 TA 100를 이용한 Ames test에서 pyrogallol-, 3,4-dihyd-roxytoluene-, hydroxyhydroquinone-SPEBRPs 들은 발암물질인 Benzo($\alpha$)Pyrene에 대하여 67.71, 63%의 강한 활성억제를 나타내었다.

In order to investigate the antimutagenicity of the sweet potato enzymatic browning reaction products (SPEBRP) were studied the DNA breaking action, spore rec assay and Ames test. In the DNA breaking action of reaction mixture of SPEBRP and polyphenol compounds with an agarose horizonal electrophoresis, catechol (CAT)-SPEBRP and hydroxyhydroquinone (HHQ)SPEBRP inhibited DNA breaking effect in the presence of $Fe^{2+}$. In the spore ree assay using Bacillus subtilis H17(rec+) and M45(rec-), 3,4-dihydroxytoluene (DHT)-SPEBRP showed strong antimutagenic effects on MNNG. In the Ames test using Salmonella tYPhimurium TA 98 and TA 100, pyrogallol(PYR)-, 3,4-dihydroxytoluene (DHT)- and hydroxyhydroquinone (HHQ)-SPEBRPs suppressed about 67%, 71% and 63% in the mutagenesis induced by Benzo($\alpha$)Pyrene(B($\alpha$)p).
