This study aimed to investigate the influence of combinating Huangqi with Fuzi on the pharmacokinetics of six Aconitum alkaloids, i.e. aconitine (AC), hypaconitine (HA), mesaconitine (MA), benzoylaconine (BAC), benzoylhypaconine (BHA) and benzoylmesaconine (BMA). The plasma concentrations of the drugs were determined by LC-MS for dose response and time dependent curves. The pharmacokinetic parameters were calculated by DAS 3.3, and SPSS 12.0 was used to analyze the differences of main pharmacokinetic parameters between the two groups. Comparing with Fuzi group, the AUC0-t and AUC0-∞ of six alkaloids in Fuzi-Huangqi group was significantly decreased, the CLz/Fof six alkaloids except HA was significantly increased; the Cmax was decreased and the tmax was prolonged in 3 monoester alkaloids, and the apparent volume of distribution of BMA and MA (Vz/F) increases. These data indicated that Huangqi can inhibit the absorption of aconite alkaloids, induce the distribution of aconite alkaloids to the whole body, and accelerate the elimination of aconite alkaloids. The animal experiment scheme in this study has been approved by the Experimental Animal Ethics Committee of Jiangxi University of Traditional Chinese Medicine.
