摘　　要：目的:优选荷叶中荷叶碱的超声提取工艺。方法:以荷叶碱的提取率为指标,首先进行单因素试验,并且在此基础上以乙醇浓度、提取温度、提取时间及料液比为影响因素进行正交设计试验,优化提取工艺。结果:当用90%的乙醇,料液比为1︰40,提取温度为60℃,提取时间为25 min,提取一次,提取率最大,此时荷叶中荷叶碱的含量占总体取物的1.12%。结论:本实验为优化荷叶中荷叶碱的超声提取工艺提供了参考依据。Objective： To optimize the ultrasonic extraction technology of nuciferine in lotus leaves. Method： In order to extract nuciferine as index, single factor test, and on the basis of ethanol concentration, extraction temperature, extraction time and solid-liquid ratio influence factors orthogonal test to optimize the extraction process. Result： When using 90 % ethanol, solid-liquid ratio was 1：40, extraction temperature of 60 ℃, extraction time 25 min, extraction once, the content of nuciferine in lotus leaf total extract 1.12 %. Conclusion： The experiment for the optimization of ultrasonic extraction of nuciferine in lotus leaves provides reference.
