Changes of serum γ-GTP, GOT and GPT levels in hepatic function-weakling subjects by ingestion of high anthocyanin sweetpotato juice

Abstract

Serum γ-GTP, GOT and GPT levels in 45 volunteers were measured before and after continual ingestion (120 ml/day) of a purple-colored juice made from sweetpotato with a high anthocyanin content. In healthy subjects, their levels did not change. However, some of hepatic function-weakling subjects showed the diminished levels of γ-GTP, GOT and GPT after 44 days of continual ingestion of the high anthocyanin sweetpotato juice. Most of such subjects belonged to a group with their high level maintaining history less than 5 years, but not more than 5 years. Such subjects were also diminished the levels of serum LDH and total bilirubin. As another information obtained in this study, among 12 subjects with blood pressure beyond 140 mmHg, two subjects showed a blood pressure decrease over 20 mmHg, and 18 subjects of all 45 volunteers told good bowel movement during ingestion period.
