摘要
为提高决明子蒽醌传统提取方法的工作效率,采用超声波研究试剂类型、提取剂浓度、超声波功率、超声时间和料液比等单因素对决明子蒽醌提取率的影响,进一步通过正交试验,确定超声波提取决明子中蒽醌的最佳工艺条件。结果表明:乙醇浓度80%、料液比1∶30、超声波功率90 W和提取时间25 min为其最佳工艺条件,在此条件下,决明子蒽醌的提取率为68.33%;而传统热回流提取工艺条件下,其提取率仅为52.04%。
Effects of dissolvant type,concentration,ultrasonic power,extracting time and solid-liquid ratio on extraction efficiency were studied by ultrasonic method to enhance the efficiency of extracting anthraquinone from Cassia tora by traditional extracting method.Further more,an orthogonal test was carried out to confirm the best technological conditions.The results showed that the best technological conditions included ethanol concentration 80%,solid-liquid ratio 1∶30,ultrasonic power 90W and extracting time 25 min.The extraction efficiency was 68.33% under optimized conditions,while only 52.04% under traditional warm immersion conditions.
