摘  要:
目的:研究油橄榄叶中橄榄苦苷超声辅助提取最佳工艺条件。方法:选定甲醇体积分数、料液比和提取时间作为影响因素,以橄榄苦苷提取率为评价指标。在单因素试验的基础上,通过3因素3水平Box-Behnken试验,建立橄榄苦苷提取率的二次多项式回归方程,经响应面回归分析得到优化组合条件。结果:最佳工艺条件为甲醇体积分数93.5%、料液比1:25(g/mL)、提取时间26min。结论:油橄榄叶中橄榄苦苷提取率可达7.83%。

摘  要:
Objective:To find optimal process conditions for the ultrasound-assisted extraction of oleuropein from Olea europaea leaves.Methods:The effects of methanol concentration,solid-to-solvent ratio and extraction time on oleuropein yield were investigated by one-factor-at-a-time design.A three-factor,three-level Box-Behnken experimental design was employed to build a second-order polynomial regression equation.The obtained regression equation was analyzed by response surface analysis to optimize the three process conditions.Results:The optimal process conditions were as follows:methanol concen-tration of 93.5%,solid-to-solvent ratio of 1:25(g/mL) and an extraction time of 26 min.Conclusion:Under these conditions,the oleuropein yield from Olea europaea leaves was up to 7.83%.
