摘 要：
[Objective] The study aimed to discuss the optimum technology condition for the ultrasonic microwave assisted extraction of isoflavonoids from Radix Pueraria.[Method]With ethanol as the extracting solvent,Radix Pueraria from Jurong as raw materials,using ultrasonic microwave assisted extraction technology,with yield of isoflavonoids as index,microwave power,extracting time,solid-liquid ratio as factors,the optimum parameters were determined.[Result] The optimum technology condition for ultrasonic microwave assisted extraction of isoflavonoids from Radix Pueraria was as follows: the extraction time was 31.2 min,the material-liquid ratio was 1∶ 30(g / ml),microwave power was 98 W,ultrasonics power was 50 W.Under the optimum conditions,the yield of isoflavonoids from Radix Pueraria was 8.92%.[Conclusion] The ultrasonic microwave assisted extraction could not only shorten the extraction time greatly,but also increase the yield of isoflavonoids from Radix Pueraria,which is a suitable method of efficient extraction of isoflavonoids from Radix Pueraria.
