[Preparation technology and quantitative analysis for beta-cyclodextrin inclusion compound of Angelica oil].

ABSTRACT

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.
