摘要:

在单因素试验基础上, 采用响应面法优化超声波辅助提取皂角刺皂苷的最佳工艺, 并考察了最佳提取工艺下提取物对α-葡萄糖苷酶和α-淀粉酶的抑制活性。实验结果表明:皂角刺总皂苷超声波辅助提取的最佳工艺为液料比16∶1(mL∶g)、乙醇体积分数60%、超声波时间80 min和提取温度50 ℃, 在此条件下皂角刺总皂苷得率为13.28%±0.25%。最佳工艺下的提取物对α-葡萄糖苷酶的半数抑制质量浓度(IC50)值为(0.146±0.019) g/L, 强于阳性对照阿卡波糖IC50值((0.48±0.18) g/L);当提取物质量浓度为2 g/L时, 对α-淀粉酶抑制率可达35.13%±0.58%, 表明皂角刺具有开发成为Ⅱ型糖尿病药物的潜力。

Abstract:

On the basis of single factor experiment, response surface methodology(RSM) was used to optimize the ultrasonic-assisted extraction optimum process of saponins from Gleditsia sinensis Thorn(GST), and the inhibitory activities of the extracts on α-glucosidase and α-amylase were investigated under the optimal extraction conditions. The results showed that the optimal ultrasonic-assisted extraction conditions were solid-liquid ratio of 16:1(mL: g), ethanol volume fraction of 60%, ultrasonic time of 80 min and extraction temperature of 50℃. Under these conditions, the yield of total saponins was 13.28%±0.25%, and the IC50 value of α-glucosidase was (0.146±0.019) g/L, which was stronger than that of positive control acarbose with the median inhibitory concentration(IC50) value of (0.48±0.18) g/L. When the mass concentration of the extract was 2 g/L, the inhibition rate of α-amylase could reach 35.13%±0.58%, indicating that GST had the potential development into a drug for type II diabetes.
