Study on the preparation process of paeonol-β-cyclodextrin

0bjective:To optimize the preparation process of paeonol-β-cyclodextrin.Methods:The optimum preparation process was selected with the orthogonal test.The optimal technological conditions were acquired by the evaluation of the availability and the encapsulation efficiencies.Results:The optimal preparation conditions of paeonol-β-cyclodextrin were as follows: the proportion of paeonol:alcohol:paeonol-β-cyclodextrin=1:24:8, ultrasound time was 40 min. Conclusion:The above preparation process gives the most rational,stable and feasible results,and increases the preparation efficiency of paeonol-β-cyclodextrin.
