摘　　要：目的:优选岗松总黄酮的大孔吸附树脂纯化工艺。方法:以总黄酮吸附率和洗脱率为指标,采用UV测定总黄酮含量,筛选最佳大孔吸附树脂,并通过单因素试验考察岗松总黄酮的大孔树脂纯化工艺。结果:采用AB-8型大孔吸附树脂对岗松总黄酮进行纯化,其最佳工艺条件为上样液生药质量浓度0.3 g.mL-1,上样流速1 BV.h-1,上样体积3 BV,加50%乙醇5BV以2 BV.h-1的流速洗脱,总黄酮纯度达52.33%。结论:优选的工艺合理可行,适用于工业化生产。Objective： To optimize purification process of total flavonoids from Baeckea frutescens L. by macroporous adsorption resin. Method： Different types of resin were selected with absorption and desorption ratio of total flavonoids as indexes, the content of total flavonoids was determined by UV, single factor test was adoptedto investigate purification technology of total flavonoids by macroporous adsorption resin. Result： AB-8 type resin was adopted, its optimum process conditions were as followings： the concentration of sample solution 0. 3 g .mL-1, absorption velocity 1 BV . h-1 , sample volume 3 BV, eluted by 5 BV 50% ethanol at flow rate of 2 BV. h-1. Under these conditions, purity of total flavonoids was up to 52.33%. Conclusion： Optimized process was rational, feasible and suitable for industrial production.
