摘要
采用超声波法提取荷叶生物碱,采用正交试验对工艺条件进行优化。结果表明最佳提取条件为65%乙醇、料液比1:50(m/V)、pH5、超声频率45kHz、超声时间0.5h、超声温度80℃,在此条件下,生物碱得率为0.17%。
Ultrasonic-assisted extraction was applied to prepare alkaloids from lotus leaves. The extraction conditions of alkaloids were optimized to maximize the yield of alkaloids by single-factor and orthogonal array methods. Under the optimized extraction conditions as follows： extraction for 0.5 h with 65 % ethanol as the extraction solvent and the solid to liquid ratio of 1：50, at 45 kHz, 80 ℃ and pH 5, the yield of alkaloids reached 0.17 %.
