| Abstract: | Objective： To establish the optimal supercritical CO2 extraction of stilbene glacoside from Polygonum multiflorum Thunb. Method： The optimum extraction conditions were investigated by L9 （34） orthogonal design and analyzed by HPLC. Result： The optimal supercritical CO2 extraction conditions were ： 40 MPa, extraction pressure ; 60℃, extraction temperature; 2 hours, extraction time;95% ethanol amount to 20% of the crude drug,modifying agent. Conclusion： It is feasible that supercritical CO2 extraction used in the extraction of stilbene glucoside from Polygonum multiflorum Thunb. |
