摘要
本文对超声波方法和传统回流方法提取苦豆子中生物碱进行试验比较,同时对超声波影响苦豆子生物碱率的多个因素进行均匀实验分析。结果表明:超声提取总苦豆子生物碱效果较好;超声波法提取的最佳方法条件为:乙醇浓度65%,提取剂pH=0·5,超声提取频率28kHz,超声提取时间20min,生物碱的提取率为75·76%。
The extraction technology of alkaloids from Sophora alopecuroides L was studied by comparing the ultrasonic wave extraction technology with the traditional extraction technology. The results showed that the ultrasonic method was betterl Also, The optimal parameters of extraction were obtained ultrasonic assistant experiments and orthogonal tests： 65% ethanol, pH 0. 5 hydrochloric acid, ultrasonic frequency 28 kHz, ultrasonic time 20min, According to the analysis of extract, the total amount of alkaloids reaches to 21. 8% in total solid substance. The extraction ratio was 75.76%.
