Zengmian Yiliu (ZMYL), a traditional Chinese formula, is designed to improve clinical efficacy and reduce adverse effects in combination with cisplatin in ovarian cancer chemotherapy. In ZMYL, Radix Paeoniae Alba (RPA, made from root of Paeonia lactiflora Pall.) acts as an adjunctive drug in cancer treatment by ameliorating side effects induced by radio‐ and chemotherapy. The pharmacokinetics differences between isomer albiflorin and paeoniflorin, the main components of RPA, after oral administration decoction of single‐herb RPA and ZMYL were compared using a sensitive and accurate UPLC‐MS/MS. The results indicate that there are statistically significant differences between the pharmacokinetic parameters: decreasing area under the plasma concentration–time curve (AUC), maximum concentration ( C max ), elimination rate constant ( K e ) and increasing apparent volume of distribution ( V d ) and clearance ( CL ) for albiflorin, increasing distribution half‐life ( T 1/2d ) and decreasing elimination half‐life ( T 1/2e ), distribution rate constant ( K d ) and absorption rate constant ( K a ) for paeoniflorin in the ZMYL group compared with the single‐herb RPA group. In comparison with albiflorin, the pharmacokinetic parameters of paeoniflorin included significantly increasing mean residence time (MRT) and V d , decreasing CL and K e in the single‐herb RPA group and increasing MRT and T 1/2d and decreasing CL , K e and K d in the ZMYL group. Both paeoniflorin and albiflorin are more likely, as the main active ingredients in RPA and ZMYL, to play a variety of pharmacological effects, and herb–herb interactions occur, resulting in different pharmacokinetics of albiflorin and paeoniflorin in RPA and ZMYL.
