Abstract

This study aimed to develop an indirect competitive enzyme-linked immunosorbent assay based on monoclonal antibodies against paeoniflorin to study the effects of different doses of glycyrrhizinic acid on the pharmacokinetics of paeoniflorin in mice. An anti-paeoniflorin monoclonal antibody was produced from a hybridoma created through a fusion of splenocytes immunized with paeoniflorin-bovine serum albumin and conjugated with the hypoxanthine-aminopterin-thymidine-sensitive mouse myeloma cell line SP2/0. The resultant antibody was used to develop and validate a rapid, specific and sensitive, indirect competitive enzyme-linked immunosorbent assay for the measurement of paeoniflorin (linear range 4.8–312.5 ng · mL−1). The intraday and interday precision values of the indirect competitive ELISA method were well within the recommended range (≤ 10 %), and the recovery rate was, on average, 101.13 %. Pharmacokinetic parameters obtained from mouse blood samples at various intervals following the oral administration of paeoniflorin and glycyrrhizic acid at three doses (1 : 0.3, 1 : 1, 1 : 3, respectively) demonstrated that the highest dose of glycyrrhizic acid inhibits the absorption of paeoniflorin.
