Abstract:
Objective: To study percutaneous absorption of cinnamic acid and the effect of some common enhancers and pH value on it. Methods: Drug permeation tests were performed in K-C two-compartment diffusion cell through excised mice skin. Samples were collected from the receiver compartment, cinnamic acid concentration in samples was determined by HPLC. Results: Cinnamic acid could penetrate through excised mice skin. The permeability coefficient of cinnamic acid rose as its concentration increased. Cinnamic acid consisted of 20% ethanol, 30% ethanol and 3% Azone had high penetrating power. Conclusion: The research will provide experimental data for skin administration of Chinese medicine holding cinnamic acid.
