By the ultrasonic extraction test of resveratrol from grape skin and grape seed,it is obtained that the best process for the extraction of resveratrol from grape skins：60% ethanol,the solid-liquid ratio 1∶12,ultrasonic time 12 min,bath with 60 ℃ water 30 min,the resveratrol extraction rate is 0.014 9%.The optimum extraction of resveratrol from grape seeds：60% ethanol,the solid-liquid ratio 1∶14,ultrasonic time 5 min,bath with 60 ℃ water 30 min,the extraction rate is 0.005 7%.Under these conditions,the extraction process is stable and easy to draw.The result also shows that the content of resveratrol in grape skin is higher than the content in the grape seed.
