摘要

目的: 优选火绒草中总黄酮的大孔吸附树脂富集纯化工艺。方法: 采用静态吸附/解吸与动态吸附/解吸相结合的方法

用紫外-可见分光光度法测定火绒草中总黄酮含量

筛选最佳大孔吸附树脂

并对其纯化工艺进行优选。结果: 确定采用HPD100型大孔吸附树脂对火绒草中总黄酮进行富集纯化

其最佳工艺条件为以2 BV火绒草供试品溶液(生药质量浓度0.1 g·mL-1)为最大上样量

吸附速率为1 BV·h-1

吸附2 h

洗脱流速4 BV·h-1

5 BV水洗脱

4 BV 30%乙醇洗脱

3 BV 50%乙醇洗脱

收集洗脱液

减压浓缩

即得。按上述最佳纯化工艺总黄酮洗脱率>90%。结论: 该优选工艺稳定可行

适合工业化生产。

Abstract

Objective: To optimize enrichment and purification technology of total flavonoids from Leontopodium leontopodioid by macroporous resin. Method: Optimum macroporous resin and its purification technology was optimized by static adsorption/desorption and dynamic adsorption/desorption.The content of total flavonoids was determined by ultraviolet and visible spectrophotometry method. Result: HPD100 macroporous resin showed good concentration and purification capabilities to total flavonoids from L. leontopodioid. Optimum technology conditions were as follows: 2 BV sample liquid (the concentration of raw drug was 0.1 g·mL-1) of L. leontopodioid was passed through HPD-100 resin in 2 h with adsorption rate of 1 BV·h-1

eluted by 5 BV water

4 BV 30% ethanol

3 BV 50% ethanol

respectively

elution flow rate was 4 BV·h-1.Eluate was collected to concentrating under vacuum.Under this optimized technology

the elution rate of total flavonoids was more than 90%. Conclusion: This optimized technology was stable

feasible

it was suitable for industrial production.
