摘  要:
试验以荷叶总黄酮的提取率为指标,通过单因素和正交试验对机械化学法辅助提取荷叶总黄酮的工艺进行了优化。结果表明,机械化学法辅助提取荷叶总黄酮的最佳工艺条件为:以水为溶剂,以Na2CO3/Na2B4O7(1∶2,m/m)为助剂,助剂用量(占物料干重)为18%,料液比(g/mL)为1∶40,提取时间为25min,提取温度为80℃。该工艺条件下,荷叶总黄酮提取率较乙醇法提高了61.1%。机械化学提取法具有提取率高、时间短、无需有机溶剂、绿色环保等优点,是提取荷叶总黄酮的一种有效方法。

摘  要:
Using the yield of total flavones extracted from lotus leaves as index, the mechanochemical process was optimized through single factor experiment and orthogonal test. The results showed that the optimum parameters for mechanochemical process of total flavones extraction from lotus leaves were as follows: water as solvent and Na2 CO3 / Na2 B4 O7(1∶2,m / m) of 18%(ratio to dry weight) as additive, the ratio of lotus leaf to water for 1∶40(g/mL), extracting 25 min under 85 ℃. Under these condition the rates of the total flavones increased 61.1% compared with alcohol extraction method. It is indicated that the mechanochemical process was an effective method to extract total flavones from lotus leaves with in higher extraction yield, shorter time and without organic solvent and more environment friendly.
