摘要
为探讨仙鹤草中总多酚的最佳提取工艺,以仙鹤草为材料,采用单因素试验和正交试验优选超声波辅助提取仙鹤草多酚的工艺条件.结果表明,用体积分数为60%甲醇溶液作提取剂,仙鹤草多酚的最佳提取工艺条件为提取温度35℃、料液比1∶20(g/m L)、提取时间25 min、超声功率480 W.在此条件下,仙鹤草总多酚提取率为1.46%,加标平均回收率为96.69%.
To study the best extraction technique of total polyphenols in Agrimoniae herba used as the material,single-factor and orthogonal tests are used and optimized the ultrasonic assistance method for the extraction process. Results show that the carbinol solution with60% volume fraction as extracting solution,the optimal extraction technique condition is the temperature 35 ℃,solid-liquid ratio 1∶ 20（ g/m L）,extraction power 480 W,extracting time 25 min. Under the condition,the yield of the polysaccharides of Agrimoniae herba was 1. 46% and plus the average recovery 96. 69%.
