| 摘 要： | 采用超声波法提取葡萄皮和葡萄籽中的白藜芦醇,由正交试验获得葡萄皮中提取白藜芦醇的最佳工艺为：乙醇提取剂浓度60%,料液比1∶12,超声时间12min,60℃水浴时间30min,白藜芦醇提取率为0.014 9%.葡萄籽中提取白藜芦醇的最佳工艺为：乙醇提取剂浓度60%,料液比1∶14,超声时间5min,60℃水浴时间30min,白藜芦醇提取率为0.005 7%.在此条件下的提取工艺稳定性好且简便易行,实验结果还显示葡萄皮中白藜芦醇的含量高于葡萄籽中的含量.

| Abstract: | 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. |
