摘要
目的:对超声波辅助法提取广西柑橘皮中橙皮苷的工艺条件进行优化。方法:通过单因素和正交试验法对超声波辅助碱提酸沉工艺条件进行考察,紫外分光光度法测定柑橘皮中橙皮苷含量。结果:超声波辅助法提取柑橘皮中橙皮苷的最佳工艺:pH13料液比1:10碱液提取,超声功率40W,超声时间40min/次,超声次数2次,提取液调节pH为4,沉淀8h,橙皮苷含量最高为4.00%(n=6)。结论:超声波辅助提取橙皮苷最优工艺稳定可行。
Objective：To study the optimization of extraction conditions on the ultrasonic-associated alkali extraction of hesperidin from Pericarpium citri retiulatae in Guangxi.Methods：The best experimental conditions were optimized by single-factor and orthogonal test,and the content of hesperidin was determined by UV-visible spectrophotometry.Results：The optimal ultrasound-associated extraction conditions were 10 times the mass of NaOH（pH=13） solution,ultrasonic power 40 W for 40 min,extracting twice,the extract was precipitated for 8 hours at pH=4.The content of hesperidin was 4.00%（n=6）.Conclusion：The optimal extraction technology was stable and feasible.
