Abstract:
OBJECTIVETo study the feasibility of supercritical fluid extraction (SFE) for arctiin from the fruits of Arctium lappa.
METHODThe extracts were analyzed by HPLC, optimum extraction conditions were studied by orthogonal tests.
RESULTThe optimal extraction conditions were: pressure 40 MPa, temperature 70 degrees C, using methanol as modifier carrier at the rate of 0.55 mL x min(-1), static extraction time 5 min, dynamic extraction 30 min, flow rate of CO2 2 L x min(-1).
CONCLUSIONSFE has the superiority of adjustable polarity, and has the ability of extracting arctiin.
