Objective: To investigate the influence of Aconiti Radix Cocta extract on percutaneous absorption of paeoniflorin and explore synergistic effect of Aconiti Radix Cocta and Paeoniae Radix Alba. Method: KM mice were randomly divided into the Paeoniae Radix Alba gel group
Paeoniae Radix Alba and Aconiti Radix Cocta gel group and Paeoniae Radix Alba-azone gel group.Microdialysis sampling was employed
the concentration of paeoniflorin in dialysate was determined by HPLC
DAS 2.0 software was used to caculate pharmacokinetic parameters of paeoniflorin
scanning electron microscope was employed to investigate the changes of mouse skin stratum corneum. Result: AUC0-t
MRT0-t
t1/2
Tmax and Cmax of Paeoniae Radix Alba gel group were (3.28±1.01) mg·L-1·h
(3.95±0.32) h
(0.92±0.44) h
(2.00±0) h and (0.72±0.24) mg·L-1;these parameters of Paeoniae Radix Alba and Aconiti Radix Cocta gel group were (10.64±1.24) mg·L-1·h
(3.35±0.08) h
(1.32±0.67) h
(1.00±0) h and (3.06±0.38) mg·L-1;these parameters of Paeoniae Radix Alba-azone gel group were (59.82±13.51) mg·L-1·h
(3.67±0.08) h
(0.89±0.16) h
(2.67±0.29) h and (13.24±4.14) mg·L-1
respectively.Scanning electron microscope results indicated that Aconiti Radix Cocta extract had the same effect on the skin surface structure as azone in exerting its permeation enhancing effect. Conclusion: Aconiti Radix Cocta extract can significantly promote transdermal absorption of paeoniflorin in herb couple of Aconiti Radix Cocta and Paeoniae Radix Alba
which may be related to the decrease of barrier function of stratum corneum and the improvement of epidermal permeability by some ingredients in Aconiti Radix Cocta.
