Abstract

Ionic liquids (ILs) were used to modify macroporous resins (MARs) to purify chlorogenic acid (CGA) with Flos Lonicera Japonicae (FLJ) extract as raw material. By comparing the static adsorption and desorption effects of four MARS, the NKA-2 resin was determined as the best purification material. The NKA-2 resin was modified by ILs to obtain the modified resin NKA-2-IL and its structure was characterized by infrared spectroscopy. The optimum conditions for the purification of NKA-2-IL MARS were investigated by single-factor experiments: sample concentration was 0.25 mg/mL, eluent was 70% (v/v) ethanol, solution pH was 3.0, sample speed was 0.4 mL/min, elution rate was 0.6 mL/min and aspect ratio was 30: 1. Under this condition, the purity of CGA increased from 5.13% to 69.08%, CGA yield was 89.5% and the purity of isochlorogenic acid (ICGA) was 22.12%. The results showed that the purification of CGA by NKA-2-IL MARS was significantly improved compared with that reported in the literature.
