Hepatoprotective effects of total saponins isolated from Taraphochlamys affinis against carbon tetrachloride induced liver injury in rats.

In this study, rats were orally treated with the total saponins of Taraphochlamys affinis (TSTA) daily with administration of CCl4 twice a week for 8 weeks. Compared to the normal control, CCl4 induced liver damage significantly increased the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in serum and decreased the activities of superoxide dismutase (SOD), catalase, glutathione peroxidase (GSH-Px), and glutathione reductase (GSH-Rd) in liver. Meanwhile content of hepatic malondialdehyde (MDA), which was oxidative stress marker, was increased.
