Objective To prepare TanshinoneⅡA loaded nanostructured lipid carriers , formulation optimization was conducted , and then evaluate its quality in vitro.Methods TanshinoneⅡA was prepared by emulsion -ultrasonic dispersion method.With encap-sulation efficiency as index and UV -visible spectrophotometry as method validation.Using orthogonal test to choose the optimal pre-scription for TanshinoneⅡA-NLC.and evaluate TanshinoneⅡA-NLC in uitro by measuring the shape and particle size , encapsula-tion efficiency , drug loading and zeta potential.Results Optimum preparation technology was as following:the amount of drug 10 mg, lipid concentration 3%, emulsifier ratio 1:1, and the solid -liquid lipid ratio 1:4.The encapsulation efficiency was (76.83 ± 1.701)%, drug loading (0.5564 ±1.113)%, particle size distributed uniform and zeta potential was -26.6 ±0.87mV with Tan-shinoneⅡA-NLC.Conclusion This prepared TanshinoneⅡA-NLC had uniform particle size distribution , high encapsulation effi-ciency and stability.
