摘要
为了提高薏苡仁油的提取效率,考察5种不同极性的溶剂(无水乙醇、丙酮、二氯甲烷、乙酸乙酯、环己烷)在3种不同的提取方法中对薏苡仁油提取率的影响,并分析其原因。结果表明,丙酮在加热回流提取法中提取率最高(8.17%),无水乙醇在超声辅助提取和微波辅助提取法中得率均较高。3种提取方法中,超声辅助提取法的得油率最高(10.79%),而微波法虽然提取效率高(0.0678g/min),但得油率太低(6.78%),不适于薏苡仁油的提取。
The coix seed oil was extracted by combination of five kinds of solvents and three types of extraction methods. Among the five tested solvents, i.e. ethanol, ethyl acetate, acetone, dichloromethane, and cyclohexane, the acetone gave the highest recovery with refluxing extraction, ethanol gave the highest recovery with ultrasound-assisted extraction and microwave-assisted extraction. In addition, the oil content of the ultrasound-assisted extraction extract was found to be higher than that of the other two extraction methods. The microwave-assisted extraction was not suitable for the extraction of coix seed oil, although it took short extraction time.
