Abstract

This study was carried out to investigate the antimutagenic affect of crude and heated comfrey extract on N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), benzo${(\alpha)}$pyrene (B${(\alpha)}$P) and 3-amino-1, 4-dimethyl-5H-pyri-do [4,3-b] indole (Trp-P-1). In spore rec-assay using Bacillus subtilis $H17(rec^+)$ and $M45(rec^-),$ crude comfrey extract showed strong antimutagenic effects on MNNG in the concentration of $40{\mu}l/disc$(p<0.01). In the Ames test using Salmonella typhimurium TA98 and TA100, the crude comfrey extract suppressed about 43% and 52% in the mutagenesis induced by $B{(\alpha)}P.$ However, the heated comfrey extract strongly suppressed about 75% and 76% in the mutagenesis in Salmonella typhimurium TA98 and TA100 induced by Trp-P-1(p<0.01).

변이원물질인 N-methyl-N'-nitro-N-nitrosoguanidine, $benzo{(\alpha)}pyrene,$ 3-amino-1,4-dimethyl-5H-pyrido[4,3-b] indole에 대한 컴프리의 생즙과 가열즙의 항돌연변이 효과를 spore rec-assay 및 Ames test방법을 이용하여 검토하였다. Bacillus subtilis $H17(rec^+)$와 $H45(rec^-)$를 사용한 spore rec-assay에서 comfrey의 생즙시료 $40{\mu}l$처리시에 MNNG에 대한 강한 항돌연변이 효과를 나타내었다(p<0.01). Salmonella typhimurium TA98과 /TA100의 두 균주를 이용한 Ames test에서는, comfrey생즙의 경우 $B{(\alpha)}P$에 대해 TA98과 TA100 두균주 모두에서 각각 43% 및 52%의 다소 낮은 항돌연변이 효과를 나타낸 반면, 가열즙의 경우 Trp-P-1에 대해 TA98과 /TA100의 균주에 대해서 각각 75% 및 76%의 강한 항돌연변이 효과를 나타내었다(p<0.01).
