| Abstract: | The best extraction conditions of Penthorum chinense Pursh from quercetin were researched.Using ultrasonic extraction , using UV spectrophotometry , rutin as comparison , the content of quercetin was determined at 370 nm.The best extraction conditions of Penthorum chinense Pursh were the concentration of 60% ethanol, ultrasonic power 50 W, ultrasonic temperature 55℃, solid-liquid ratio 1：25 , and ultrasonic time 60 min.Under the conditions , quercetin leaching rate was the highest.The ultrasonic extraction process was stable and feasible. |
