[Study on preparation of beta-cyclodextrin inclusion compound of volatile oil from Aucklandia lappa]
1Nanjing University of Traditional Chinese Medicine, Nanjing 210029.
Objective:
To study optimum inclusion process conditions for volatile oil from Aucklandia lappa.
Methods:
The study was carried out with orthogonal design. The process conditions were studied by determining the utilization ratio of volatile oil from Aucklandia lappa, the oil-bearing rate and extract ratio of inclusion compound.
Results:
The optimum preparation conditions for inclusion were established as: oil: beta-CD was 1:8, the inclusion temperature and time were at 40 degrees C and for 1 h respectively, the utilization ratio of oil is 87.1%.
Conclusion:
The method can be used for production of beta-CD on a large scale.
