摘要
以桑葚渣为原料,采用超声辅助提取方法获得水提物并对其α-淀粉酶和α-葡萄糖苷酶的抑制活性进行检测,通过L_9(3~4)正交试验优化了桑葚渣水提物的超声辅助工艺。结果表明:在最佳的提取工艺,即提取时间1.5 h、料液比1∶40(g·mL^(-1))、超声温度50℃、超声功率350 W条件下,提取液对α-淀粉酶和α-葡萄糖苷酶活性的抑制率分别为76.4%、81.4%。
Mulberry fruit was extracted with deionized water using ultrasonic-assisted method and inhibition rate to alpha-amylase and alpha-glucosidase activities by the extracts was monitored.The extraction process was optimized by L9(34)orthogonal test.The results showed that,under the optimum conditions,i.e.1.5 h of extraction time,1∶40(g·mL^-1)in the ratio of material to liquid,50℃in ultrasonic temperature and 350 W in ultrasonic power,the inhibition rate of the mulberry fruit extracts to alpha-amylase and alpha-glucosidase was 76.4%and 81.4%,respectively.
