| Abstract: |
| [Objective] To investigate and optimize the penetration enhancer in Jinwanghong compound recipe. [Methods] Franz diffusion of isolated abdominal skin of rats was used to investigate the penetration-promoted effect of propylene glycol, Azone, Labrasol and Transcutol respectively and optimize the excellent penetration enhancer and the dose. [Results] Selecting gallic acid as the index component, the accumulative permeation quantity per unit area of propylene glycol was surpassed the others with a steady state flow 0.721 μg/(mm2·h). The penetration-promoted ratio was 1.646 folds higher. The optimal dosage was 5%. [Conclusion] Analysis based on the effective constituents and matrix miscibility has found that propylene glycol is the optimal penetration enhancer. Since its higher viscosity, its used dosage should not be too large. |
