摘　　要：为获得高得率的超声波辅助萃取波罗蜜Artocarpus heterophyllus种子多酚工艺,通过单因素试验和正交试验考察了超声温度、超声时间、超声功率、乙醇浓度、料液比5种因素对超声波辅助萃取波罗蜜种子多酚产量的影响。结果表明,5种因素对波罗蜜种子多酚产量影响的大小顺序为:乙醇浓度>超声温度>料液比>超声时间>超声功率;其最佳萃取工艺条件为超声温度45℃、超声时间10 min、超声功率55 W、料液比1∶50(g·mL^-1)、乙醇浓度60%,在此条件下波罗蜜种子多酚产量可达5.368 mg·g^-1。Experiments were conducted on technology of ultrasonic-assisted extraction of polyphenols from Artocarpus heterophyllus seeds with different ultrasonic temperature,ultrasonic time,ultrasonic power,ethanol concentration and solid-liquid ratio.Single factor and orthogonal test on 5 factors above-mentioned demonstrated that effect of factors was ordered by ethanol concentration>ultrasonic temperature>material to liquid ratio>ultrasonic time>ultrasonic power.Experiments indicated that the optimal extraction technology was under 45℃ultrasonic temperature,10 min ultrasonic time,55 W ultrasonic power,1:50 solid-liquid ratio,and 65%ethanol concentration.The yield extracted from A.heterophyllus seeds was 5.368 mg/g.
