Objective To prepare the emodin transfersome and to evaluate its quality.Methods Emodin transfersome was prepared by film-ultrasonic dispersion method.The effects of the ratio of different components in the transfersome products on encapsulation efficiency were investigated.The rates of envelopment of emodin transfersome were determined by ultraviolet spectrophotometry(UV).The particle size and Zeta potential of emodin transfersome were evaluated by Zetasizer analyzer.Results The appropriate formulation was cholesterol vs phospholipids 1 ∶ 3,deoxycholic acid sodium salt vs phospholipids 1∶ 6,emodin vs phospholipids 1∶ 10,vitamin E vs phospholipids 1∶ 20.Zeta potential was-15.11 mV and the particle size was 292.2 nm.The mean encapsulation efficiency was(65.35 ±0.25) %.Conclusion The preparation method is simple and reasonable,showing high encapsulation efficiency and stability.
