Abstract:
Objective To optimize the experimental condition for CO 2 supercritical fluid extraction(SFE)of volatile oil from Marchantia convoluta andto analyse the extract.Methods Orthogonaltestwas applied.SFEtechnology was usedto optimize the extractionconditionfor volatile oilfrom Marchantia convoluta and the solventextractionwas useda s the control.The extract was analyzed by GC-MS and HPLC.Results The optimal extraction conditions f or the volatile oil were:pressure at15MPa,heatingtemperatureat50℃,addingt hemodifier ofalcohol30mLtoextractfor2h,flowingratebeing10L /hand theabsorbefa-cient solution being alcohol .Twent y -three peaks were isolated and 19components were identified,accounting 82.61%.Conclusion SFEmethodhas theadvantages of shorterextractiontimeandhighextractionefficiencyas comparedwiththet radi-tionalsolventextraction.
