Abstract
The antimutagenicity of the 3-sophoroside-5-glucoside of cyanidin and 3-sophoroside-5-glucoside of peonidin, the anthocyanin derivatives deacylated from the 3-(6,6'-caffeylferulylsophoroside)-5-glucoside of cyanidin (YGM-3) and 3-(6,6'-caffeylferulyl-sophoroside)-5-glucoside of peonidin (YGM-6) which had been purified from the sweetpotato with purple-colored flesh, was investigated by using Salmonella typhimurium TA 98. A comparison of the antimutagenicity between YGM-3 and YGM-6 and the deacylated derivatives showed that the activity of cyanidin was stronger than that of peonidin. Deacylation of the peonidin-type pigment markedly decreased this antimutagenicity. Caffeic acid showed the strongest antimutagenicity of the constituent organic acids of the anthocyanin pigments, caffeic acid, ferulic acid, and p-hydroxybenzoic acid. These results suggest that the cathecol structure plays an important role in the strong antimutagenicity of anthocyanin pigments.
