ABSTRACT
AIM:
To optimize the extraction process for the active components in Curcuma by supercritical CO_2 as guided by the contents of curcumol in Curcuma.METHODS:
Gas chromatography was used to determine the contents of curcumol in the extract.Uniform design and path analysis were used to optimize SFE process.RESULTS:
The optimum process was established as following20 MPa as extracting pressure,40℃ as extracting temperature,120 minutes as dynamic extracting time and 20 minutes as static extracting time,24 mL of 70% alcohol as modifier.The absolute error of the predicted value from the model was smaller than 0.6%.CONCLUSION:
The regression model is very notable and reasonable and can forecast results precisely.
