ABSTRACT
OBJECTIVE:
To optimize the technology of supercritical CO2 extraction from Zingiberis rhizoma.METHODS:
With the comprehensive score of the contents of 6-ginger phenol,8-ginger phenol and 10-ginger phenol and the extraction rate of the oil from Z. rhizoma as the index,uniform design method was adopted to investigate the effects of extraction pressure,extrac-tion temperature and extraction duration on the extraction result;verification tests were conducted.RESULTS:
The optimal condi-tions were as follows as the extraction pressure of 25 MPa,extraction temperature of 30 ℃ and extraction duration of 2 h. In the verification tests,the average extraction rate of the oil from Z. rhizoma was 3.2%(n=3),and the comprehensive score was 1.874 2 (RSD=0.65%,n=3),with the relative deviation of 0.6% between the measured value and the predicted value.CONCLUSIONS:
The optimal extraction technology is stable and feasible,with the advantages of low temperature,short duration.
