摘要
对6种不同类型大孔树脂吸附荔枝核黄酮的性能进行了比较,筛选出效果较好的HPD-300大孔树脂用于纯化荔枝核黄酮,考察了HPD-300大孔树脂的吸附纯化特性和吸附动力学.实验结果显示HPD-300大孔吸附树脂是理想的吸附树脂,采用该树脂,产品中黄酮的纯度可提高到74%,动力学研究表明吸附过程符合Langmuir吸附模型和Freundlich吸附模型.
Macrophorous resin HPD-300 was selected by comparing the properties of adsorption and desorption of 6 types of macroporous resins for flavonoids from Litchi seed. The adsorption character and absorption kinetics of macrophorous resin HPD-300 for flavonoids from Litchi seed were investigated. The result showed that macrophorous resin HPD-300 was a kind of preferable macroporous resin for flavonoids from Litchi seed, and the purity of flavonoids in product was up to 74%. The absorption kinetics indicated the adsorption date fitted well into the Lang- muir and Freundlich adsorption isotherm mode process.
