摘要:
采用微波辅助提取技术，以葛根总黄酮提取率为指标，以溴化1丁基3甲基咪唑(［bmim］Br）水溶液为提取剂提取葛根总黄酮.分别考察了提取时间、提取温度、微波功率、提取液浓度以及固液比对葛根总黄酮提取率的影响.结果显示，葛根总黄酮提取最佳条件为：提取剂［bmim］Br水溶液浓度为1.0 mol/L，最佳固液比为120，微波功率为500 W，提取温度为70 ℃，萃取时间8 min，其粗黄酮的提取率为8.05%.与传统的乙醇提取方法相比，萃取率要高13.5%，使用的溶剂量少，微波功率低，快速高效，且提取率高.
Abstract:
 A Microwaveassisted extraction (MAE) method of flavonoids from radix puerariae by［bmim］Br solution were investigated.The extraction condition of solidliquid ratio,concentration of solvent,time,temperature and microwave power were researched,respectively.The MAE conditions were that the solvent was 1.0 mol/L［bmim］Br solution,the solid/liquid (g:mL) ratio was 120,the microwave power was 500 W,the extraction temperature was 70 ℃,and time was 8 min.Under these MAE conditions,the yield of flavonoids in Radix Puerariae is 8.05%.Compared with traditional ethanol extraction method,the yield of the extraction by［bmim］Br solution increased by 13.5%.The advantage of the method is Lowsolvent consumption,low microwave power,fast,efficient and highyield.
