Abstract

Purpose: To investigate the hepatoprotective effect of Ipomoea batatas extract against alcohol-induced liver damage in mice.

Methods: Male C57BL/6 mice were randomly divided into 4 experimental groups (n = 10). Normal Group: The animals received distilled water 5 ml/kg for 7 days; Alcohol Group: The animals received alcohol 5 ml/kg of 40 % w/v alcohol for 7 days; Alcohol + Purple sweet potato leaf extract (PSPE) Group: PSPE 400 mg/kg was for 7 days. The animals received alcohol 5 ml/kg of 40 % w/v alcohol for 7 days; Alcohol + Hovenia dulcis Thunb extract (HDE) Group: HDE 400 mg/kg was for 7 days. To confirmed to the liver protection effect of PSPE, it was calculated, and the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), and total cholesterol (TC) in serum were detected. To evaluate changes of histological in alcohol-fed mice, liver tissue was determined by H&E staining.

Results: Blood alcohol concentration in purple sweet potato leaf extract (PSPE) 200 mg/kg and Hovenia dulcis (H. dulcis) extract (HDE) 200 mg/kg treated group significantly decreased compared to -alcohol with water treated group (p < 0.05). Serum ALT (alanine aminotransferase) and AST (aspartate aminotransferase) were markedly reduced. Liver sections in mice stained with H&E (hematoxylin and eosin) stain to displayed the physiological changes in the liver tissue. Furthermore, the results showed that inflammatory cells increased in the alcohol group compared to the normal group, but spontaneously decreased in the PSPE or HDE-treated group.

Conclusion: These results demonstrate that Ipomoea batatas may be therapeutically effective in protecting the liver from alcohol-induced hepatotoxicity and fatty liver.
