摘要：目的研究红景天酪醇的超声波提取工艺,同时对提取过程进行数学模拟。方法采用高效液相色谱法,以酪醇含量为指标,通过正交设计及数学模拟优化红景天酪醇的超声波提取工艺。结果红景天酪醇最佳超声波提取工艺为:80%乙醇为提取溶剂,料液比为1∶35(g∶mL),提取时间30 min,超声功率240 W。在此条件下,酪醇提取率可达0.150 1%。与加热回流法比较,提取时间缩短66.7%,提取效率提高12%。结论该提取方法操作简单,有效成分提取率高。超声波提取的数学模拟值与试验结果吻合。
Objective To study the ultrasonic extraction technology of tyrosol in Rhodiolae Crenulatae Radix et Rhizoma;To mathematically simulate the extraction process. Methods The content of tyrosol was set as index;HPLC was used;the ultrasonic extraction process of tyrosol in Rhodiolae Crenulatae Radix et Rhizoma was optimized by an orhogonal experiment and mathematic simulation. Results The optimum ultrasonic extraction conditions were as follows:80%ethanol was used as extraction solvent, the ratio of material to liquid was 1∶35(g∶mL), with the extraction time of 30 min and ultrasonic power of 240 W. In these conditions, the extracting rate of tyrosol was 0.150 1%. Compared with the heating reflux method, the extraction time should be shortened by 66.7% and the extracting rate should be increased by 12%. Conclusion The extraction method is simple and the extraction rate of effective components is high. Mathematical simulation values based on ultrasonic extraction are consistent with experiment values.
