聚酰胺分离纯化黄栌叶漆黄素工艺研究
Study on separation and purification process of fisetin from Cot i nus coggygria leaves with polyamide
摘要
Abstract
To study the separation and purification of fisetin from Cotinus coggygria leaves with polyamide by using the adsorption rate and elution rate of fisetin as index.The effects of sample flow rate,sample concentration,concentration of eluent and dosage on purification process were investigated from static and dynamic ad-sorption.The optimum process conditions were as followed:the sample flow rate was 1 mL/min,the sample concentration was 0.535 8 mg/mL,the sample volume was 2 BV,the eluent was 70% etha-nol,and the eluent dosage was 4 BV.Conclusion:The crude extract of Cotinus coggygria leaves was refined three times under optimum conditions,which increased from 10.30% to 79.82%,and the purity increased 6.75 times.关键词
