摘　　要：目的 :选择提取葛根总黄酮的最佳方法 ,研究了用渗鹿法、浸渍法、煎煮法、回流法提取葛根总黄酮。方法 :采用紫外分光光度法测定提取液中的总黄酮含量。结果 :用回流法得率最高 ,其次为渗漉法 ,用煎煮法提取得率最低 ;在渗漉法中以乙醇为溶剂 ,速度为 2ml/kg·min的渗漉法提取的总黄酮得率最高。结论 :渗漉法是合适的提取方法。Objective: In order to select the best process of extraction of the flavonoids in Radix puerariae. Methods: Percolation, maceration, decoction and reflux were adopted, and the flavonoids in Radix puerariae was determined by UV spectrophotometry. Results: The yield order is reflux, percolation, maceration, and decoction; the percolation with alcohol and a flow rate of 2ml/kg·min is the most effective in the percolation methods. Conclusion: It indicates that the percolation is the most suitable to extraction of the flavonoids.
