We examined the hepatoprotective effects of colored potato flakes on acetaminophen (AAP)-induced liver damage in rats. F344/DuCrj (8 week-old) rats were fed a cholesterol-free diet with 54.9486 g of -corn starch/100g diet and were orally treated with 25% colored flakes of Kitamurasaki (KM: light purple), Northern Ruby (NR: red), and Shadow Queen (SQ: medium purple) potatoes co-administered with AAP (0.5 g/100 g diet) for 4 weeks. The hepatic thiobarbituric acid-reactive substances (TBARS) values in the KM, NR, and SQ groups were significantly lower (p<0.05) than those in the control groups with and without AAP. Furthermore, the hepatic catalase, Mn-superoxide dismutase (SOD), and Cu/Zn-SOD mRNA levels in the KM, NR, and SQ groups were higher than those in the control groups with and without AAP. The present findings suggest that colored potato flakes are useful as a prophylactic agent against oxidative liver damage.
