摘  要:
通过正交试验,对微波辅助萃取葛根总异黄酮的工艺条件进行了研究,结果表明:用90%的乙醇,葛根粒度为40目,固液比为1:15,预浸泡1~2h,微波辐射40s,葛根总黄酮的浸出率达96%以上,与传统的热浸提相比,不仅产率高,而且速度快、节能。

摘  要:
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.
