离子交换纤维纯化绿原酸的研究

Study on extraction of Chlorogenic acid by using Ion exchange fiber

目的对金银花中绿原酸的提取工艺进行研究.方法以乙醇为溶剂,采用动态吸附实验考察优化的吸附-解吸条件.结果离子交换纤维提取绿原酸的优化工艺条件为:吸附时间60min,流速4·0ml?min-1,解吸时以甲醇-盐酸(1mol?L-1)=4∶1混合溶液作为解吸剂,流速为0·8ml?min-1.结论离子交换纤维应用于绿原酸的提取中效果好,适宜于产业化生产.

OBJECTIVE To observe the extraction process of Chlorogenic acid from Flos Lonicerae. METHODS Acording to dynamic adsorption experiments, to observe the optimal adsorption-elution conditions of extraction with ethanol as solvent. RESULTS Optimal conditions for the extraction of Chlorogenic acid with Ion exchange fiber were obtained the time of adsorption was 60min,and the velocity was 4. 0 ml·min^-1 ,thc velocity of elution was 0. 8 ml·min^-1 with the mixture（4：1） of methanol and hydrochloric acid（（1mol· L^-1 ） as the elution solvent. CONCLUSION Ion exchange fiber was optimal adsorbent in the extraction of Chlorogenic acid,and can be used in industry.
