Abstract:Objective] To optimize the extraction process of volatile oil from green Asparagus officinalis L.powder and analyze its components,so as to provide basis for the further research and comprehensive application of green Asparagus officinalis L.powder.Method] The extraction process of supercritical CO2 extraction was optimized by four factors and three levels orthogonal test with extraction content of volatile oil as evaluation index,and the chemical compositions of the extraction were analyzed by GC-MS.Result] The optimal extraction conditions of supercritical CO2 extraction for essential oil from green Asparagus officinalis L.powder were determined to be CO2 flow rate of 20L/h,extraction temperature of 35 ℃,extraction pressure of 25 MPa and extraction duration of 2h,under which the extraction rate of volatile oil from green Asparagus officinalis L.powder was up to 98%.Thirty-seven components were isolated and obtained from the volatile oil,of which contents of hydrocarbons and aldehydes and esters ranked the first and second respectively.Conclusion] The extraction rate of essential oil from green Asparagus officinalis L.powder by SC-CO2 is relative higher under the optimum extraction conditions,which provides basis for the further research and comprehensive application of green Asparagus officinalis L.powder.
