摘　　要：A fast,reliable,and cost-effective liquid chromatography-tandem mass spectrometry method was established to determine the effects of the traditional Chinese medicine employed to treat coronavirus disease 2019,namely,Lianhua Qingwen granules,Huoxiang Zhengqi capsules,Jinhua Qinggan granules,Shufeng Jiedu capsules,and Angong Niuhuang pills,on the pharmacokinetics of lopinavir/ritonavir in rats.Blood samples were prepared using the protein precipitation method and atazanavir was selected as the internal standard(IS).Separation was performed on an Agilent ZORBAX eclipse plus C18(2.1 mm×50 mm,1.8 μm)column using acetonitrile and water containing 0.1%formic acid as the mobile phase for gradient elution.The flow rate was 0.4 mL/min and the injection volume was 2 μL.Agilent Jet Stream electrospray ionization was used for mass spectrometry detection under positive ion multiple reaction monitoring mode at a transition of m/z 629.3→447.3 for lopinavir,m/z 721.3→296.1 for ritonavir,and m/z 705.4→168.1 for the IS.The method showed good linearity in the concentration range of 25→2500 ng/mL(r=0.9981)for lopinavir and 5e500 ng/mL(r=0.9984)for ritonavir.The intra-day and inter-day precision and accuracy were both within±15%.Items,such as dilution reliability and residual effect,were also within the acceptable limits.The method was used to determine the effects of five types of traditional Chinese medicines on the pharmacokinetics of lopinavir/ritonavir in rats.The pharmacokinetic results showed that the half-life of ritonavir in the groups administered Lianhua Qingwen granules and Huoxiang Zhengqi capsules combined with lopinavir/ritonavir was prolonged by approximately 1.5-to 2-fold relative to that in the control group.Similarly,the pharmacokinetic parameters of lopinavir were altered.Overall,the results of this study offer important theoretical parameters for the effective clinical use of five types of traditional Chinese medicines combined with lopinavir/ritonavir to reduce the occurrence of clinical adverse react
