摘要: 为探寻骆驼蓬中抗氧化性物质的最佳提取方法，采用不同极性溶剂提取与均匀设计法相结合进行试验。以骆驼蓬为研究对象，DPPH清除自由基抗氧化活性抑制率为测试指标，对均匀设计实验数据进行二次多项式逐步回归分析。结果筛选甲醇作为最佳提取溶剂，其抑制率为76.64%。得到最优提取工艺条件：提取3次，提取时间20 min，料液比1:14 g/mL，通过验证此时骆驼蓬的甲醇提取物DPPH清除自由基抗氧化活性的抑制率为75.13%，为最佳提取工艺。
Abstract: In order to optimize the extraction process of antioxidants in Peganum harmala L., different solvent extraction combined uniform design method were employed in this research. With the inhibition rate of DPPH scavenging free radical antioxidant activity as the test index, the experimental data of uniform design were analyzed by quadratic polynomial stepwise regression. Methanol was selected to be the optimum extraction solvent with an inhibition of 76.64%. The optimum extraction conditions are as follows: extract is 3 times; extraction time is 20 min; liquid-solid ratio is 1:14 g/mL. At this time, the inhibition rate of scavenging DPPH free radical antioxidant activity of methanol extract from Peganum harmala L. was 75.13%, which was the best extraction process.
