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L9(34)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%。

Abstract: 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.

Key words: mulberry fruit, ultrasonic assisted extraction, alpha-amylase activity, alpha-glucosidase activity, process optimization
