Abstract: CO2-SFE and ethanol refluxing methods were repectively used to extract 1’-acetoxychavicol acetate(ACA) from Alpinia galanga(L.) Swartz. The qualities of ACA extracts with the two methads were evaluated by TLC and HPLC chromatogram,effective composition content of ACA and physical index respectively. The results showed CO2-SFE extract is purer,and the content of ACA is 72.11% in the volatile oil of the extract,and the net content of ACA is 5.6 times of that in ethanol refluxing extarct. In conclusion,CO2-SFE is obviously better than ethanol refluxing method for extracting effective componen ACA from Alpinia galanga(L.) Swartz.

Key words: CO2-supercritical fluid extraction(SFE), ethanol refluxing method, ACA
