Abstract:: Taking Jasminum duclouxii as test materials，the technology of extraction of the total flavonoids from the root of Jasminum duclouxii was studied to provide a reference for it’s further study and utilization，taking the root of Jasminum duclouxii as material，and alcohol as extractant，the effect of solid-1iquid ratio，ethanol concentration，extracting time and microwave power on the extraction of the total flavonoids from the root of Jasminum duclouxii was investigated using the methods of single factor test and orthogonal design test of L9(34).The results showed that the highest extraction rate (2.21%) of the total flavonoids in the root of Jasminum duclouxii could be obtained under conditions of solid-1iquid ratio 1∶20 g/mL，50% ethanol，extracting time 60 seconds，microwave power 350 W.The microwave-assisted extraction of flavonoids from Jasminum duclouxii was simple and practical，which was time saving，energy conserving and high efficient.
