| Abstract: | Determination of quercetin from Conyza bonariensis by HPLC and microwave-assisted ex- traction was reported. The effects of solvent concentration, microwave time, ratio of solution to solid and mi- crowave-assisted extraction pressure were evaluated. The extraction conditions of quercetin from Conyza bonariensis by microwave - assisted method were optimized ： ethanol concentration is 60 % （~/V） ; micro- wave time is 10 min; ratio of solution to solid is 45：1 and microwave-assisted extraction pressure is 500 kPa. The relative standard deviation is 1.13%- 2.39% and the recovery is 99.75%- 101.38%. Microwave-as- sisted extraction and high performance liquid chromatography was simple and accurate with good reproduc- ibility. |
