| Abstract: | The taxifolin from Polygonum orientale L. is extracted by the method of ultrasonic pretreatment with heat reflux. The optimal extraction conditions for taxifolin from Polygonum orientale L. are determined by the response surface analysis. Results show that the optimal extraction conditions are that the ultrasonic time is 20rain; the ultrasonic treatment temperature is 50℃; the ultrasonic power is IOOW; the ethanol concentration is 55% ; the heat reflux extraction temperature is 87℃; the ratio of solid to liquid is 1：22 （M： V） ;the heat reflux extraction time is 2h; the extracting times is 2, and the extraction of Polygonum orientale L. taxifolin under this condition is 3.56mg · g^-1. |
