Abstract:The objective of this study was to optimize the supercritical fluid CO2 extraction of volatile oil from Perilla frutescens leaves. Single factor and orthogonal design methods were used to investigate the effects of pressure, temperature, extraction time and CO2 flow rate on extraction rate of volatile oil. Pressure of 20 MPa, temperature of 35 ℃, CO2 flow rate of 10 kg/h and extraction time of 150 min were found optimum. Under the optimal extraction conditions, the extraction rate of volatile oil was up to 3.2%.
Keywords:Perilla frutescens  supercritical fluid CO2 extraction  volatile oil
