摘要: 以息半夏的块茎为原料,乙醇为超声波辅助提取溶剂,考察乙醇体积分数、超声时间、料液比、超声温度等单因素对总生物碱提取率的影响,设计正交试验优化提取工艺,并测试总生物碱的体外抗氧化和降血糖活性。结果表明,最佳提取条件为乙醇体积分数65%、提取时间60 min、料液比1∶45、超声温度65 ℃,总生物碱的提取率达0.502%;总生物碱对DPPH、ABTS自由基的清除率分别达89.90%和43.60%,对α-葡萄糖苷酶的抑制率达86.40%。该工艺简单可行,总生物碱表现出良好的体外抗氧化和降血糖生物活性。

Abstract: Taking the tuber of Pinellia ternata as raw material and ethanol as ultrasonic-assisted extraction solvent, the influence of single factors such as ethanol volume fraction, ultrasonic time, material-liquid ratio and ultrasonic temperature on total alkaloids extraction rate was investigated. The orthogonal test was designed to optimize the extraction process, and the in vitro antioxidant and hypoglycemic activities of total alkaloids were tested. The results showed that the optimal extraction condition was ethanol volume fraction of 65%, extraction time of 60 min, the material-liquid ratio of 1∶45, ultrasonic temperature of 65 ℃, and the extraction rate of total alkaloids was 0.502%; the clearance of DPPH and ABTS radicals reached 89.90% and 43.60%, respectively, and the inhibition of α-glucosidase reached 86.40%. The process was simple and feasible, and the total alkaloids showed good in vitro antioxidant and hypoglycemic biological activities.

Key words: Pinellia ternata, total alkaloids, orthogonal test, antioxidant, hypoglycemic action
