Objective:
To optimize the preparation process of beta-cyclodextrin (beta-CD) inclusion compound of Angelica oil.
Methods:
Single factor experiment and orthogonal design were used together, oil inclusion rate was used as an index, then chose the best preparation technology.
Results:
The optimal method was saturated solution method. The preparation condition for inclusion was as follows: the ratio of Angelica oil to beta-CD was (1: 8), the ratio of beta-CD to water was (1: 6) and the stirring time was 4 h.
Conclusion:
The preparation procedure of inclusion volatile oil is simple, stable, reliable and high inclusion rate.
