Abstract:
Objective:To study the effect of tannins from Pericarpium Granati on hepatic microsomal enzyme in rats. Methods:Thirty Wistar rats were randomly divided into five groups:the blank control group, high, medium and low dose groups of tannins from Pericarpium Granati, the positive control group of phenobarbital sodium. The blank control group was given physiological saline. The three different doses groups were respectively given tannins from Pericarpium Granati orally at the dose of 150,100 and 75 mg·kg-1 · d-1 for 7 days. The positive control group was given phenobarbital sodium 80 mg·kg-1 ·d-1 with intramuscular injection for 5 days. At the end of the experiment, the activity ofⅠandⅡphase metabolic enzymes in liver microsomes of each group was determined by UV. Results:Compared with the blank control group, the high, medium and low dose groups of tannins from Pericarpium Granati could sig-nificantly decrease the content of CYP 450 and CYPb5, and inhabit the activity of ADM (P<0. 01);the high and medium dose group could significantly inhibit ERD enzyme activity (P<0. 01);the high dose group could significantly reduce GST enzyme activity (P<0. 01). Conclusion:Tannins from Pericarpium Granati has notably inhibitory effect on hepatic microsomal enzyme in rats, which can reduce the expression of CYP3A and CYP2E1 in a dose-dependent manner.
