In the preformulation study, the ultraviolet spectrum and HPLC methods for the assay of α-asarone were established firstly and then the physicochemical properties, especially the octanol/water partition coefficient and the solubility in various solvent systems such as alcohol, PEG 400, IPM, octanol were examined. The prediction permeability was then compared with actual transdermal parameters obtained from the in-vitro diffusion study , and feasibility of drug transdermal absorption was then analyzed.
