AIM: To investigate the effect of severe acute pancreatitis (SAP) on pharmacokinetics of Da-Cheng-Qi Decoction (DCQD) components in rats. METHODS: Rats were divided into SAP group and sham-operation group as a control group (n = 6). Rhein, chrysophanol, rheochrysidin, magnolol, hesperidin and naringin in DCQD were quantified in rat serum by high performance liquid chromatography tandem mass spectrometry for studying their pharmacokinetics. RESULTS: Early absorption of each DCQD component was tended to degrade in SAP group after treatment with DCQD by gavage. The C-max (chrysophanol, P = 0.0059; rheochrysidin, P = 0.0288; magnolol, P = 0.0487; hesperidin, P = 0.0277; naringin, P = 0.0023) and AUC (rhein, P = 0.0186; chrysophanol, P = 0.0013; magnolol, P = 0.001; hesperidin, P = 0.0081; naringin, P = 0.0272) of DCQD component were obviously lower in SAP group than in control group. The T-1/2 alpha of chrysophanol and rheochrysidin (P = 0.0467 and 0.0005, respectively) and T-max of chrysophanol and rheochrysidin (P = 0.0101 and 0.0037, respectively) lasted longer in SAP group than in control group. CONCLUSION: SAP can significantly impact the absorption of DCQD components in rats and their pharmacokinetic parameters. (C) 2009 The WJG Press and Baishideng. All rights reserved.
