摘要
利用超声波辅助提取法提取蒲公英中的生物碱。在单因素试验的基础上,通过正交试验对超声波辅助提取蒲公英中生物碱工艺进行优化,得到最佳的提取工艺为物料粒度0.150 mm(100目),乙醇体积分数80%,料液比1∶12,提取时间5 min。在此条件下,蒲公英生物碱的得率达0.234%。
The extraction technology of dandelion alkaloids by ultrasonic assisted was studied. Based on single factor test, orthogonal design was used to optimize ultrasound assisted technology for extracting al- kaloid from dandelion. The best extraction conditions were determined as below: mesh number of material 100 mesh, concentration of alcohol 80%, ultrasound extraction time 5 min, ratio of material-liquid 1 : 12. Under these conditions, the yield rate of alkaloid could be 0.234%.
