摘要
建立高效液相色谱检测柚皮苷含量的方法,通过单因素试验考察提取时间、提取功率、乙醇体积分数和固液比4个因素对柚皮苷提取率的影响,在此基础上运用正交试验法优化柚皮苷的提取工艺。结果表明:柚皮苷的最佳提取工艺为用50%的乙醇,按固液比1∶25进行超声提取60 min,超声提取功率50 W。该优选工艺合理、稳定可行,在此优化条件下提取柚皮苷的含量是6.134%。
A high performance liquid chromatographic method was developed for determining the content of naringin.The effects of ultrasonic time, ultrasonic power,ethanol concentration and solid-liquid ratio factors on the narngin extraction rate were investigated by single-factor experiments.Based on the above work ,the extraction technology of naringin was optimized by orthogonal experiment.The optimal extraction technology was as follow：the ethanol concentration was 50%,the solid-liquid ratio was 1∶25,the ultrasonic power was 50 W and extracting time was 60 min. The extraction content of naringin was 6.134%by the above method.
