Abstract:ObjectiveTo study different methods of essential oil extraction from Atractylodes lancea (Thunb.) DC.and determine the optimum extraction method.MethodsSteam distillation 、Ultrasonic extraction、Soxhlet extraction and Superfluid extraction CO2 were compared with the extraction yield and content of Atrctylodin in the essential oil from Atractylodes lancea (Thunb.) DC as indexes.ResultsYield of SFE-CO2 was 10.61% ,and content of Atrctylodin of SFE-CO2 was 28.62%,which was higher than the other three methods.ConclusionThrough comparing four kinds of methods , we can see SFE-CO2 is better than the other three methods. It has the best quality about extraction yield and content of Atrctylodin in the essential oil, it is suit for extracting the essential oil from Atractylodes lancea (Thunb.) DC.
