采用微波联用超临界 CO2萃取菊三七生物碱，将菊三七粉末用乙醇水溶液浸泡、微波辐照处理后，再用超临界 CO2萃取，对乙醇浓度、浸泡时间和微波辐照时间等实验条件进行单因素实验，得出浸泡液乙醇浓度为90%，浸泡时间为10 h，微波处理时间为2 min 为优化条件，并与单一采用超临界 CO2萃取的试验进行了比较。结果表明，微波联用超临界萃取技术用于菊三七生物碱的提取效率优于单一采用超临界萃取技术。

Radix Gynurae Segeti alkaloids were extracted by the microwave / supercritical fluid extraction. A certain Radix Gynurae Segeti powder soaked into some certain ethanol with different concentration,and then dealed with it using microwave,after that extracted by supercritieal CO2 . Experimental conditions such as ethanol concentration, time of soak and time of microwave dealing with were optimized. Opital conditions:ethanol concentration was 90% ;soak time was 10 h;time of microwave dealing was 2 min. Camparison of microwave / supercritical CO2 extraction and supercritical CO2 extraction was carried out. The results showed that microwave / supercritical CO2 extraction is better than supercritical CO2 extraction.
