Oral Absorption of Long Circulating Nano-liposomes of Quercetin in Mice
摘要
Abstract
Objective To prepare long circulating nano-liposomes of quercetin( QUE-LCL ) and investigate the physical and chemical properties and oral absorption in mice. Methods The QUE-LCL was prepared by the emulsified evaporation-low temperature solidification method with Glyceryl bebenate( ATO ) and Tween 80 as carriers and the optimum formulation selected by orthogonal test. Its morphology was examined by transmission electron microscope( TEM ) and the particle diameter distribution was detected. The quereetin determination in nanoparticles and the mixture of gastrointestinal contents and feces by HPLC were established. Results QUE-LCL was spherical shape with mean diameter of 172. 63 nm and entrapment efficiency was 91.77% . The oral absorption of QUE-LCL in mice was better than that of quercetin suspension and common liposomes.Conclusion The emulsified evaporation-low temperature solidification is suitahle for preparing QUE-LCL, and the preparation of which made by orthogonal test promotes the oral absorption of quercetin in mice.关键词
