Objective:To investigate the plasma pharmacokinetics of six representative components(nodakenin,ost-hole,5-O-methylvisammioside,ferulic acid,liquiritigenin,and liquiritin),which were the ingredients of Qianghuo Shengshi Decoction(QSD)granules,in normal and rheumatoid arthritis(RA)rats administrated QSD granules intragastrically.Methods:A rapid and accurate ultra-high performance liquid chromatography-tandem mass spectrome-try(LC-MS/MS)method was developed for the simultaneous determination of six components in plasma,and it showed a good specificity,linearity,intra-day and inter-day precision,intra-day and inter-day accuracy,extraction recovery,stability,and the less matrix effect.Results:The validated LC-MS/MS method was successfully used to compare the plasma pharmacokinetics of six ingredients between normal and RA rats after intragastrical administration of QSD granules and dif-ferences in the pharmacokinetics were found in two types of rats.The absorption rate in the RA rats was lower for nodakenin,osthole,5-O-methylvisammioside,liquiritigenin and liquiritin than in the normal group,while the absorption rate of ferulic acid remained constant in two groups.In comparison with the normal rats,the exposure concentration of nodakenin was higher and that of other five components except for nodakenin was lower under pathological conditions.Additionally,the absorptive amount of nodakenin,osthole,5-O-methylvisammioside and liquiritin was increased and that of ferulic acid and liquiritigenin was reduced in the RA rats than in the normal rats.Compared with the normal rats,the reten-tion time of nodakenin,ferulic acid and liquiritin was reduced in vivo,whereas the retention time of ost-hole,5-O-methylvisammioside and liquiritigenin was raised in the body for the RA rats.In contrast to the normal rats,the data demonstrated an increase in the elimination velocity of nodakenin and a decrease in the elimination velocity of the other five components except for nodakenin in the pathological state.Conclusion:This study showed that the pharmacokinetic behavior of the six components,nodakenin,ost-hole,5-O-methylvisammioside,ferulic acid,liquiritigenin,and liquiritin,is different in vivo between nor-mal and pathological states of rats,and this research provided the necessary experimental data to explain the pharmacokinetics of QSD granules in both normal and pathological states and provide some references for its clinical application at some level.
