The purpose of the present work was to prepare nanoscale complex liposome loaded both aqueous soluble drug tea polyphenols (TP) and insoluble drug vitamin E (VE) by reverse-phase evaporation method. The preparation formulation of TP-VE complex liposome was optimized by the orthogonal experiment. The entrapment efficiency of TP was (50.81 ± 1.91)% while that of VE was (94.05 ± 3.45)% for the optimal formulation. The results of penetration experiments of TP-VE liposome demonstrated a slight influence of the concentration of TP and the content of cholesterol on the penetration quantity of TP. These results indicate that the complex liposome offers a new approach to entrap aqueous soluble drug and poorly soluble drug, an inner liposome protection, a relatively high drug encapsulation efficiency and a sustained transdermal penetration.
