摘要
在单因素试验的基础上,采用响应面法对超声波辅助提取枳实中生物碱辛弗林的工艺进行优化,预测得到最实验佳条件。结果表明:超声波法提取枳实中生物碱辛弗林的最佳工艺条件为枳实颗粒度30目、乙醇体积分数67.90%、液固比12:1(mL/g)、提取时间16min、超声功率420W,在此条件下,辛弗林的提取量达到5.87mg/g。该工艺提取结果与理论预测值5.77mg/g基本吻合,说明该优化方法可行。
On the basis of one-factor-at-a-time experiments, response surface methodology was employed to the ultrasoundassisted extraction of synephrine from Citrus aurantium fruit. A quadratic regression model was established to investigate the extraction yield of synephrine with respect to three extraction parameters such as ethanol concentration, material particle size and ultrasound treatment time. The optimal extraction conditions determined were material particle size of 30 mesh, ethanol concentration of 67.90%, liquid-to-solid ratio of 12：1 （mL/g）, extraction time of 16 min, and ultrasonic power of 420 W. Under these conditions, the extraction yield of synephrine was up to 5.87 mg/g, which was consistent with the predicted value of 5.77 mg/g. Thus, the established regression model had good feasibility.
