- 摘要:
- 以灯盏花为原料,利用正交实验对灯盏乙素提取的工艺参数进行了优化研究。结果表明:料液比为1∶2、甲醇浓度为80%和超声时间为30 min的提取方案最优,其精密度和重复性试验的相对标准偏差仅为0.19%和2.46%,加标回收率达到了99.88%。通过正交设计优化后的灯盏乙素提取方法具有较好的重复性和可行性。
- Abstract:
- Taking Erigeron breviscapus (Vant.) Hand-Mazz as material,the extraction process of scutellarin was optimized by orthogonal experiment.The results showed that the most excellent technology was moderate ethanol concentration 80%,solid-liquid ratio 1∶2 and ultrasonic time 30 min.The RSD of precision and repeatability experiment were 0.19% and 2.46% respectively,and the recovery of standard addition was 99.88%.Therefore,the extraction technology which optimized by the orthogonal experimental was better repeatability and reliability.
