Objective:
To study optimum inclusion process conditions for volatile oil from Rhizoma Curcumae.
Method:
The study was carried out with orthogonal design. The process conditions were studied by determining the utilazision ratio of volatile oil from Rhizoma Curcumae, the oil-bearing rate and extract ratio of inclusion compound.
Results:
The optimum preparation conditions for inclusion were established as: volatile oil:beta-CD was 1:8, the inclusion temperature was at 80 degrees C and inclusion time for 3 h, ultilizasion rate of volatile oil was 86%.
Conclusion:
The method can be used for mass production.
