采用超临界CO2萃取、酸水溶液提取、超声波辅助浸提等3种方法提取槲寄生碱。结果表明,超临界CO2萃取的最佳工艺条件是A2B1C1D3,即温度50℃,压力25MPa,时间1h,夹带剂氯仿;酸水溶液提取的最佳工艺条件是1.5%的盐酸回流提取6h;超声波辅助浸提的最佳工艺条件是A1B2C2,即乙醇体积分数100%,超声时间30min,固液比30∶1。
Mistletoe alkaloids were extracted by three methods: supercritical CO2 extraction, aqueous acid extraction and ultrasonic assisted extraction. The results showed that the optimum conditions for the extraction of supercritical carbon dioxide were A2B1C1D3, that is, the temperature was 50 ℃, the pressure was 25MPa, the time was 1h, the entrainer chloroform was the best extraction condition; the optimal extraction conditions were 1.5% hydrochloric acid reflux extraction for 6h; The optimum conditions for the extraction are A1B2C2, that is, the volume fraction of ethanol is 100%, the ultrasonic time is 30min and the solid-liquid ratio is 30:1.
