摘要
利用4种大孔吸附树脂分离纯化银杏叶总黄酮。结果表明,HPD100型大孔吸附树脂最适合分离纯化银杏叶总黄酮,该树脂的静态饱和吸附量(以干树脂计)为63.8 mg.g-1,静态洗脱率为91.2%,动态饱和吸附—洗脱量为14.0 mg.g-1,洗脱剂为70%乙醇,洗脱剂用量为4倍树脂体积,树脂可重复使用7个周期。
The total flavones from Folium ginkgo leaves were seperated and purified by four kinds of macroporous adsorption resin. The results showed that resin HPD100 was the most efficient one with static adsorption capacity of 63.8 mg·g^-1, static elution rate of 91.2% and dynamic saturated adsorption capacity of 14.0 mg·g^-1 with 4 BV 70% ethanol as eluting reagent. Furthurmore, resin HPD100 could be repeatly used for 7 cycles.
