大孔吸附树脂对丁香叶中丁香苦苷类成分富集工艺研究

Objective: To study the optimal conditions and parameters for the enrichment process of syringopicroside in Folium syringae with macroporous resin. Methods: With the enrichment degree of syringae as an index, the analytical method of HPLC was developed , AB-8 resin was selected as the medium for purification of syringae on the basis of comparing six kinds of macroporous resin’s adsorption and separation performance,and the optimal conditions of the enrichment process were investigated. Results: The optimal conditions were that the extract of Folium syringae was taken into AB-8 resin column, the resin was washed by 4 times of distilled water to get rid of impurity and 5 times of 50% ethanol to elute syringae. Conclusion:The process is a effective method to enrich syringae,and provides a way to research new medicine delivery system.
