[Study on condition for extraction of arctiin from fruits of Arctium lappa using supercritical fluid extraction].
OBJECTIVE
To study the feasibility of supercritical fluid extraction (SFE) for arctiin from the fruits of Arctium lappa.


METHODS
The extracts were analyzed by HPLC, optimum extraction conditions were studied by orthogonal tests.


RESULTS
The 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).


CONCLUSIONS
SFE has the superiority of adjustable polarity, and has the ability of extracting arctiin.
