Objective:
To study the optimum preparation process of the volatile oil of Dalbergia odorifera-beta-cyclodextrin.
Methods:
The saturated water solution mixing method was compared with microwave method and ultrasonic method by determining the ultilization ratio of the volatile oil in Dalbergia odorifera. The optimum preparation conditions were investigated by the orthogonal design. The quality of the volatile oil before and after included were analyzed by TLC.
Results:
The optimum preparation conditions for inclusion were as follows: m(volatile oil of Dalbergia odorifera): m (beta-CD) = 1:10 (g/g), ultrasonic time was 1h, the temperature was 70 degrees C. The ultilization ratio of the volatile oil was 82.02%.
Conclusion:
Ultrasonic method is the best method.
