Evaluation of the hepatotoxic potential of Tinospora crispa and its isolated borapetosides B, C and F in a murine model.

Abstract

The hepatotoxic potential of the methanolic extract of the stems ofand of its furano-diterpenoid-borapetosides B, C, and F-was investigated in normal and health-compromised mice. Health-compromised condition was established by a single intraperitoneal injection of LPS (6 mg/kg). Two different sets of experiments were conducted to evaluate the hepatotoxic potential. A 21-day study where the mice were dosed with the extract of(1 gm/kg b. wt./day) or standardized combination of borapetosides B, C and F (500 mg/kg b. wt.) with or without a single dose of LPS (1 gm/kg b. wt./day). In the acute toxicity study, mice were dosed with borapetosides B, C, and F (500 mg/kg b. wt.). Results showed that the ALT levels were normal and liver histopathology unaltered. No conclusive hepatotoxicity was observed in the methanolic extract or pure compounds tested under the given experimental conditions.
