Abstract: This study was designed to increase stability and hydrophilicity of cinnamaldehyde through hydroxypropyl-β-cyclodextrin inclusion technology. In this study, associative efficiency(CE)was set as screening parameter and optimal formulation of cinnamaldehyde-hydroxypropyl-β-cyclodextrin inclusion complex was obtained using solvent evaporation method based on single factor screening and orthogonal design. Under the selected formulation, mass ratio of cinnamaldehyde to hydroxypropyl-β-cyclodextrin was 1∶15 and composite time was 15 minutes under supersonic condition with mass concentration ratio of 1∶8. For the selected formulation, CE of inclusion complex could reach 90% and storage stability remained in 3 months under 4 ℃, which provides basis for practical application.

Key words: cinnamaldehyde, hydroxypropyl-β-cyclodextrin inclusion complex, orthogonal screening, formulation optimization
