| 摘 要： | 采用酸性染料比色法测定紫金龙(Dactylicapnos scandens)总生物碱的含量,通过正交设计方法,以总生物碱提取率为评价指标,优化超声波辅助提取工艺。结果表明,超声波辅助提取总生物碱的影响因素大小顺序为乙醇体积分数>提取时间>料液比,用料液比为1∶9(m/V,g∶mL),90%(V/V,下同)的乙醇溶解,超声波辅助提取40 min为最佳提取工艺条件,此工艺条件下,总生物碱提取率为2.69%。

| Abstract: | Orthogonal design was used to optimize ultrasonic assisted technology for extracting total alkaloids from Dactylicapnos scandens.The content of total alkaloids was determined by acidic dye colorimetry and used as the index of extracting effect.The order of factors influencing extracting effect was alcohol concentration> ultrasonic time > solid-liquid ratio.The optimal extraction craft was ultrasonic assisted extracting for 40 min using 9-fold of 80% ethanol,under which the yield of total alkaloids could be ... |
