Abstract: Microwave-assisted extraction process for the total Isoflavones from Pueraria root powder was studied by normalexperiment, The result of quantitative analysis of total isoflavones indicates that under the condition of 90% alcohol, the grindingdegree was 40 mesh, the ratio of solid to liquid was l:15 , the dipping time was 1~2h, the radiation time was 40s, the extractingrate of total isoflavones was more than 96%.Compared to the traditional extraction, microwave-assisted extraction not onlyprovides higher production rate but also has the advantage so being fast and energy saving.

Key words: microwave-assisted extraction, Pueraria Lobata, total Isoflavones, normal experiment
