ABSTRACT
Objective To optimize the extraction of volatile oil from Qingjie Granules and process of inclusion compound of beta-cyclodextrin. Methods Water Distillation was used for extraction. Extraction time, grinding degree, and the amount of water were set as inspection factors, and volatile oil volume was set as the evaluation index to inspect extraction process of volatile oil from Qingjie Granules. With inclusion rate as the evaluation index, the single factor test and the Box-Behnken combined with the response surface method were used to choose the optimum inclusion process. Results The optimum extraction process for Schizonepetae Herba, Saposhnikoviae Radix and Forsythiae Fructus coarse powder should be with 10 times amount of water, extracting 3 h. Inclusion method should be saturated water solution method, and the inclusion process of volatile oil as feed and beta-cyclodextrin inclusion ratio was 112; the temperature was 40 ℃; inclusion time was 3.5 h. By means of TLC, UV and IR spectra, the formation of the inclusion compound of volatile oil in clear solution particles was preliminarily proved. Conclusion The optimum extraction and inclusion process of volatile oil from Qingjie Granules are stable and feasible, which can be used in industrial production.
