| Abstract: | Objective]To optimize the ultrasonic extraction conditions of resvetrarol from peanut roots,stems and leaves.Method]With peanut roots,stems and leaves as materials,the extraction process was optimized by orthogonal test based on single factor test.Result]The optimal extraction conditions were determined to be ultrasonic frequency of 15.33 kHz,1∶ 2 of duty cycle,6 min of extraction duration,solid to liquid ratio of 1∶ 25 and ethanol concentration of 70%.The content of resvetrarol in samples reached as high as 885.96 μg/g under the optimum extraction conditions.Conclusion]The optimal ultrasonic extraction process is obtained in this study,which provides a new means for the efficient extraction of resverarol from peanut roots,stems and leaves. |
