Rats were orally administered with DCQD (10 mL/kg.BW). Pancreatic tissues were collected 24 h after a single dosage of DCQD. The concentrations of the 10 components of DCQD were determined by HPLC-MS/MS. The results are presented as the mean ± SD of μg/mg (n = 6). NG(a): the sham-operated group with the dosing time at 4 h after operation. 4hG(a), 12hG(a) and 24hG(a): rats were dosed orally with DCQD at 4 h, 12 h and 24 h, respectively, after AP induction. 4hG(a) vs NG(a):

^aP < 0.05, 12hG(a) vs 4hG(a):

^cP < 0.05, 24hG(a) vs 12hG(a):

^eP < 0.05. AP: Acute pancreatitis; DCQD: Da-Cheng-Qi decoction; HPLC-MS/MS: High-performance liquid chromatography tandem mass spectroscopy.

Rats were orally dosed with DCQD (10 mL/kg.BW). Plasma samples were collected from the tails at 10 min, 20 min, 40 min, 1 h, 2 h, 4 h, 8 h, 12 h and 24 h after a single dosage of DCQD. The samples were assessed by HPLC-MS/MS. The pharmacokinetic parameters were processed by pharmacokinetic statistic software DAS2.0.1 and the data were obtained by statistical moment calculation. The results are presented as the mean ± SD. NG(a): the sham-operated group with the dosing time at 4 h after operation. 4hG(a), 12hG(a) and 24hG(a): rats were dosed orally with DCQD at 4 h, 12 h and 24 h, respectively, after AP induction. Compared with NG(a):

^aP < 0.05, 12hG(a) vs 4hG(a):

^bP < 0.05, 24hG(a) vs 12hG(a):

^cP < 0.05, 24hG(a) vs 4hG(a):

^dP < 0.05. AP: Acute pancreatitis; DCQD: Da-Cheng-Qi decoction; HPLC-MS/MS: High-performance liquid chromatography tandem mass spectroscopy.
