[Preparation and characterization of herba pogostemonis, rhizoma atractylodis and radix aucklandiae compound essential oil-beta-cyclodextrin complex].
OBJECTIVE
To prepare and characterize Herba pogostemonis, Rhizoma atractylodis and Radix aucklandiae compound essential oil-beta-cyclodextrin complex.


METHODS
The essential oil-p3-cyclodextrin complex was prepared by colloidal mill method. TLC, XRD, DSC and TGA analysis were applied to characterize it.


RESULTS
The complex inclusion rate of essential oil-beta-CD complex was 82.4%, and the complex recovery was 80.7%. The formation of essential oil-beta-CD complex was proved by the results of TLC, XRD, DSC, TGA analysis.


CONCLUSIONS
The stability of compound essential oil is improved by the preparation of oil beta-cyclodextrin complex.
