Objective To study the best preparation conditions of d-borneol-β-cyclodextrin inclusion complex and its structure characterization. Method The inclusion complex was prepared by the methods of saturated solution method, ultrasonic method, and grinding method with composite grade as index. To obtain the best preparation conditions of inclusion complex, L9(34) orthogonal test design was carried out. The structure of inclusion complex was identified by the methods of thin layer chromatography (TLC), Fourier infrared spectrum (FIIR) and X-ray powder diffractometry (XRD). Results The optimum preparation conditions were as follows: ratio of d-borneol and β-cyclodextrin was 1:6, ultrasound temperature was 40 ℃, ultrasound time was 60 min. The yield of inclusion complex was over 88.59%, and the inclusion ratio of inclusion complex was over 95.98% under the optimum conditions. The formation of inclusion complex was proved by TLC, FIIR, and XRD. Conclusion This technology has good inclusion rate and yield, and the d-borneol-β-cyclodextrin inclusion complex exhibits some new physical characteristics.
