中文摘要: 以鄂薯 4 号甘薯茎叶为材料，通过单因素和正交试验对超声波乙醇浸提法提取甘薯茎叶总黄酮的工艺进行研 究。结果表明，超声波乙醇浸提法提取甘薯茎叶总黄酮的最佳提取工艺为：超声温度 40 ℃、乙醇浓度 70 %、料液比 1 ∶ 40（g/mL）、超声时间 30 min，在此工艺条件下甘薯茎叶总黄酮的得率可达 2.65 %。
Abstract:The extraction of total flavonoids was studied using the ultrasonic and ethanol from stems and leaves of 'ESHU-4'sweet potato，The methods were applied through the single factor experiment and orthogonal experi－ ment. The results showed that the ultrasonic and ethanol immersion extraction was used to extract the optimum extraction condition of total flavonoids from stems and leaves of sweet potato was：40 ℃ ultrasonic extraction temperature，70 % volume fraction of ethanol，liquid material ratio 1 ∶ 40 （g/mL） and 30 min ultrasonic extrac－ tion time. Under the optimum conditions， the total flavonoids extraction rate of sweet potato stem and leaf was 2.65 %.
