Abstract

Objective:To compare the four extractions and determine content of β-elemene.Methods:β-Elemene was determined by GC.Results:The yields and β-Elemene of four extractions were different. The yield of SFE-CO 2 was 12.09%, β-Elemene was 7.84%; steam distillation (SD) was 1.58%, β-Elemene was 8.15%; Ultrasonic extraction (SC) was 5.75%, β-Elemene was 1.48%; Soxhlet extraction (SX) was 3.56%, β-Elemene of was 1.48%.Conclusion:The yield and β-Elemene of SFE-CO 2 are better than SD|SC and SX, the method is found to be superior to SD|SC and SX.
