Objective:To study the pharmacokinetics of curcumin microcystin in rats.Methods: The microcystin was orally administrated.After carotid artery cannulation
blood samples were collected after administration of 0.08
0.25
0.5
0.75

5.5 h
and tested by HPLC.Results: The various doses of curcumin concentration-time curve is bimodal;Cmax
1
and Cmax
2
of each dose group are as follows: high-dose(0.90
1.20 mg/L)
medium dose(0.43
0.46 mg/L)
low dose(3.16
1.31 mg/L); AUC are 3.79
2.60
5.92 mg·h/L respectively.Cmax and AUC of low dose are greater than that of the high and medium doses.Conclusion: The Pharmacokinetics of curcumin were nonlinear process in rat
there may be the phenomenon of enterohepatic circulation.
