摘要
以大豆粉末磷脂为原料,采用离子液体超声波辅助萃取的方法对磷脂酰肌醇进行了分离提取研究。考察了不同萃取次数、料液比、乙醇-离子液体(氢氧化1-丁基-3-甲基咪唑,[Bmim]OH)溶剂比、萃取温度、萃取时间和萃取功率对磷脂酰肌醇纯度和提取率的影响。结果表明:萃取次数3次,料液比1∶12(w/v),溶剂乙醇-[Bmim]OH体积比100∶7(v/v),萃取温度35℃,萃取时间15 min,萃取功率360 W条件下磷脂酰肌醇的纯度为79.53%±3.26%,提取率为68.26%±1.15%。
The extraction methods of phosphatidylinositol from soybean lecithin powder by ionic liquid and ultrasonic wave were studied.The effects of extraction times,solid-liquid ratio,ehanol-[Bmim]OH ratio,extraction temperature,extraction time and ultrasonic power on the purity and extraction ratio of phosphatidylinositol were investigated.The purified phosphatidylinositol products were obtained at the conditions as follows:extraction times 3,solid-liquid ratio 1∶12,ehanol-[Bmim]OH ratio100∶7,extraction temperature 35℃,extraction time 15 min and ultrasonic power 360 W.Under these conditions,the purity and extracting yield of phosphatidylinositol were 79.53%±3.26%and 68.26%±1.15%,respectively.
