Microwave Extraction of Total Isoflavones From P.Lobata

摘要: 该文研究了利用微波萃取葛根异黄酮的工艺。结果表明：用77%的乙醇，固液比为1∶14，在体系温度低于60℃的条件下，微波间歇处理3次，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。

Abstract: Microwave extraction of total isoflavones from P.Lobata powder was studied. The result of quantitative analysis of total isoflavones indicates that under the condition of 77% alcohol, the ratio of solid to liquid is 1∶14, the temperature was at below 60℃, and the solution was treated at regular intervals for three times, the extracting rate of total isoflavones was more than 96%. Compared to the traditional extraction, microwave extraction not only provides higher production rate but also has the advantages of being fast and energy saving.
