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