Abstract: In this study, a simple preparation approach was developed for modified bisphenol A (BPA) molecularly imprinted polymer sorbent used in the hollow fiber solid phase microextraction (MIP-HF-SPME) of chlorogenic acid (CGA). The pre-polymer solution containing the template was introduced into the polypropylene hollow fiber segment for in situ polymerization. MIP-HF-SPME conditions based on the modified MIP-sorbent were optimized. Finally, the tool was used for selective extraction of chlorogenic acid in Echinacea…
