摘要
试验采用微波辅助提取不同季节女贞子中齐墩果酸。在单因素试验的基础上,通过正交试验对不同季节女贞子中齐墩果酸的提取条件进行优化。结果表明:6月份女贞子中齐墩果酸最佳提取工艺条件为乙醇体积分数80%,料液比1∶12(g/mL),微波时间3 min,微波功率300 W,微波温度50℃,此条件下齐墩果酸提取率为2.82%;9月份女贞子中齐墩果酸最佳提取工艺条件为乙醇体积分数60%,料液比1∶14(g/mL),微波时间4 min,微波功率300 W,微波温度60℃,此条件下齐墩果酸的提取率为3.11%。
The microwave-assisted extraction technology of oleanolic acid from different season Fructus ligustri lucidi was studied.The extraction technologies were optimized through orthogonal test based on single factors test.The results showed that：the optimum conditions of oleanolic acid from Fructus ligustri lucidi in june were ethanol volume fraction of 80%, ratio of solid to liquid 1：12 （g/mL）, microwave time of 3 min, microwave power of 300 W, microwave temperature of 50 ~C,and the extraction rate of oleanolic acid was 2.82% under optimal extraction conditions.The optimum conditions of oleanolic acid from Fructus ligustri lucidi in september were ethanol volume fraction of 60%,ratio of solid to liquid 1：14 （g/mL） ,microwave time of 4 min,microwave power of 300 W,microwave temperature of 60 ℃ ,and the extraction rate of oleanolic acid was 3.11% under optimal extraction conditions.
