Effects of an ethanolic extract prepared from G. lutea ssp. symphyandra roots on the bile production and liver in rats were investigated. Bile flows of rats which were treated by a single i.p. dose of CCl4 24 h prior to experiments were measured after the cannulation of bile duct under urethane anaesthesia. After an equilibration period of 1 h, the lyophilized extract were administered intraduodenally (500 mg/kg i.p.), while control animals received physiological saline only. To monitor the effect of multiple dose therapy, rats received the same dose of G. lutea ssp. symphyandra extract for 3 days (2 days prior to CCl4 administration) and their bile flows were measured after the cannulation. In all groups, bile samples were collected for 3 h with 15 min intervals. After the completion of bile flow experiment, rat livers were removed and put in neutral formaldehyde solution (10%) for the histological examination. According to results obtained, multiple dose treatment of rats with the plant extract normalized the decreased bile now due CCl4, whereas single dose therapy was ineffective on the impaired bile flow These data indicate that the extract prepared from Gentiana lutea ssp. symphyandra roots has a hepatoprotective activity.
