| 摘 要： | 采用微波辅助提取紫苏叶中迷迭香酸,通过响应面分析对提取工艺进行优化,得出较优工艺条件为微波功率560 W,处理时间为4.5 min,料液比为1∶33(每33 mL溶液中含有1 g物料),迷迭香酸产率为2.55 g/mg.通过对微波辅助提取和常规提取工艺的比较,可以得出利用微波辅助提取紫苏叶中迷迭香酸的工艺是可行的.

| Abstract: | Microwave-assisted extraction of rosmarinic acid in perilla frutescens leaves was optimized by response surface method.The optimal process conditions were as follows,the microwave power 560 W,processing time 4.5 min,solid-liquid ratio 1∶33(1 g sdid in 33 mL solvent).Under the optimal conditions,the rosmarinic acid yield reached 2.55 g/mg.Compared with conventional extraction process of rosmarinic acid in perilla frutescens leaves,microwave-assisted extraction process is feasible. |
