[Objective]This study was to optimize the extraction process of resveratrol from RHIZOMA ET RADIX POLYGONI CUSPIDATI. [Method]An orthogonal design was adopted to investigate the effects of extraction temperature, extraction time and ultrasonic power on the extraction rate of resveratrol from RHIZOMA ET RADIX POLYGONI CUSPIDATI by using ultrasonic-assisted wave method. [Result] The optimum extraction process of resveratrol was found as follows: extraction temperature of 80 ℃, extraction time of 45 min and ultrasonic power of 200 W. Under the above conditions, the extraction rate of resveratrol could reach as high as 0.940%. [Conclusion] The ultrasonic-assisted technology is liable and simple, which is a safe and efficient method for extracting resveratrol from RHIZOMA ET RADIX POLYGONI CUSPIDATI.
