The UPLCMS/MS was used to analyze the pharmacokinetics of Rg1, Re, Rb1, and Rd after orally administration of P. ginseng and P. ginseng combined with Raphani Semen to rats. Pharmacokinetic differences of four ginsenosides between single uses of P. ginseng and combined with Raphani Semen were investigated.Results: The results showed that Raphani Semen tended to significantly reduce the anti-fatigue activity of P. ginseng. Co-administration of P. ginseng and Raphani Semen had significant effects on the pharmacokinetics of the four ginsenosides in rats compared to that observed with P. ginseng extract alone. The AUC0–12 hvalues of the four ginsenosides in PG group were higher than the corresponding values in the PR group. It can be inferred that Raphani Semen decreased the blood exposure of the four ginsenosides in rats when it combined with P. ginseng.Conclusion: The anti-fatigue activity and pharmacokinetic results showed that Raphani Semen may reduce the pharmacological actions of P. ginseng.展开更多
