Objective： In order to prepare resveratrol nanostructured lipid carrier （Res NLC） and screen the best preparation process and the optimal prescription. Methods： The nanostructured lipid carriers were prepared by sol vent evaporation low temperature curing method and used solid lipids, liquid lipids and surfactants as the excipi ents. Then the preparation of Res NLC was investigated using particle size, encapsulation efficiency and drug load ing as indicators, process and formulation prescriptions. Results： The single factor and orthogonal test results showed that the best preparation technology was the optimal formulation. Under the optimum conditions, the encap sulation efficiency of Res NLC was 84.87 %, and the drug loading was 8.48%. Conclusion： The entrapment efficiency and particle size of resveratrol nanostructured lipid carriers meet the requirements of the pharmacopoeia on the quality of nanoparticles.
