中文摘要:

选择8种大孔吸附树脂,根据它们对金褐霉素的吸附率和解吸率,筛选较优的金褐霉素吸附剂;并且对金褐霉素提取纯化的样品进行红外光谱、核磁共振检测分析,鉴定分析提取工艺的效果。结果表明:X-5大孔树脂具有较好的吸附性能和解吸效果,优化了金褐霉素提取纯化的工艺条件;红外光谱、核磁共振检测结果鉴定了金褐霉素的结构及其理化性质,进一步证明该提取工艺达到较为理想的效果。

英文摘要:

In this article,the optimal parameters for extracting Aureofuscin were investigated by studying the adsorption and desorption rate of Aureofuscin among eight macroporous resins. The determination of the physical and chemical properties of Aureofuscin was carried by IR,NMR spectrum method. The results showed that X -5 resin possessed higher absorption and desorption rate,the finished Aureofuscin product was detected by IR and NMR spectrum,proved that the isolation and purification technology achieved general ideal effect.
