Abstract
In this study,the supercritical carbon dioxide extraction of Chrysanthemum morifolium volatile oil was optimized by single factor and orthogonal array design methods with respect to the effects of extraction pressure and temperature,length of extraction time and carbon dioxide flow rate.The optimum extraction conditions were determined as follows: extraction pressure 20 MPa,extraction temperature 55 ℃ and carbon dioxide flow rate 10 kg/h for an extraction duration of 2 h.Under such conditions,the oil yield was 5.92%.
