Empirical Study on the Extraction of Volatile Rose Oil by Supercritical Fluid Extraction / 中国药房

ABSTRACT

OBJECTIVE:To extract volatile rose oil by the supercritical fluid extraction technology.METHODS:The optimum extraction technology condition was investigated by orthogonal experiment with extraction rate as the evaluation in?dex,and with the pressure,temperature of extraction and the flow of CO 2 as investigation factors(3levels of each were cho?sen).RESULTS:The optimum technology condition was the followingthe extraction pressure was25MPa,the temperature was50℃and the flux of CO 2 was600L/h.CONCLUSION:The established method has the following meritshigh extraction rate,fast speed,simple technics,pollution-free,pure extraction etc.
