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。
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.
