ABSTRACT
Objective To prepare quercetin liposomes and establish a method for determination of its entrapment efficiency.Methods The film dispersion-homogenizing method was used to prepare quercetin liposomes.The formulation was optimized on the basis of orthogonal design and its entrapment efficiency was performed by the protamine sedimentation method.Results The optimal conditions were found to be cholesterol-egg phospholipid=13,quercetin-vehicle = 140,homogenization pressure 103.4 MPa for three times.The average entrapment efficiency of the optimized nano-liposomes was 92.1%.Conclusion The film dispersion-homogenizing method could be used to prepare quercetin liposomes.The protamine sedimentation method is convenient,accurate,and suitable for the determination of the entrapment effi- ciency of quercetin liposomes.
