Gentiopicroside (GPS), a main bitter secoiridoid constituent of roots of Gentiana macrophylla Pall., was tested for therapeutic effects on the two hepatic injury models, the CCl4-induced and lipopolysaccharide (LPS)/bacillus Calmette-Guerin (BCG)-induced hepatitides. An increase in serum level of hepatic aminotransferases (GOT: EC 2.6.1.1. and GPT: EC 2.6.1.2.) induced by a p.o. treatment of CCl4 was suppressed by pretreatment with GPS at 30-60 mg/kg/day for 5 consecutive days. An increase of these enzymes triggered by an i.v. treatment with LPS in mice primed with bacillus Calmette-Guerin (BCG) was also inhibited by GPS pretreatment at the same dose of GPS. In the BCG/LPS model, tumor necrosis factor (TNF), a major inflammatory mediator, was increased in serum with a peak at 90-120 min, followed by an increase of serum transaminase activities. GPS treatment significantly suppressed the increase of TNF in serum at the therapeutic doses, suggesting that GPS protected against hepatitis by inhibiting the production of TNF.
