Empirical Study on the Extraction of Volatile Rose Oil by Supercritical Fluid Extraction

Deng Yuan

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 inˉdex,and with the pressure,temperature of extraction and the flow of CO 2 as investigation factors(3levels of each were choˉsen).RESULTS:The optimum technology condition was the following:the extraction pressure was25MPa,the temperature was50℃and the flux of CO 2 was600L/h.CONCLUSION:The established method has the following merits:high extraction rate,fast speed,simple technics,pollution-free,pure extraction etc.
