摘要:
为测定紫丁香叶总黄酮得率并确定其微波提取条件，在微波提取过程中，通过单因素试验分析固液比、微波功率、乙醇浓度、微波辐射时间及提取次数等主要因素对提取率的影响，并通过正交试验优化提取工艺条件。结果表明：微波提取紫丁香叶总黄酮最佳工艺条件为固液比1∶25，微波功率为480 W，乙醇浓度为50%，微波辐射时间为50 s，在该工艺条件下紫丁香叶总黄酮得率可达0.611%。微波法提取效率高，操作简便，省时且无污染，是提取紫丁香叶总黄酮的有效途径。
Abstract:
The content of total flavones in leaves of Syringa oblate was determined and the microwave extraction condition was confirmed.During the extracting process，main factors including solid-liquid ratio，microwave power，ethanol concentration，microwave radiation time and extraction times were studied by single factor experiment.The extraction conditions were optimized by orthogonal experiment.The result showed that the optimum extraction conditions were determined as follows:solid-liquid ratio was 1∶25，microwave power was 480 W，ethanol concentration was 50%，and microwave radiation time was 50 s.Under the conditions the yield of total flavonoids in leaves of Syringa oblate could reach 0.611%.The microwave extraction technology was high efficiency，convenient operation，time saving and no pollution.It was an ideal way to extract the total flavonoids from leaves of Syringa oblate.
