Adsorption can be an effective way of purifying polyphenols from complex mixtures. However, polyphenols may be present in small concentrations, making it difficult to selectively adsorb them onto standard hydrophobic resins and obtain appreciable adsorption. In this work, nonfunctionalized hydrophobic resins (Amberlite XAD-7HP, XAD-16) are compared with functionalized resins with imidazole (Biotage RENSA PX) and pyridine (RENSA PY) in terms of capacity and selectivity toward p-coumaric acid, trans-resveratrol, and naringenin. The obtained results indicate that, due to hydrogen bonding, the functionalized resins provide more capacity (e.g., 80 mg·g–1 vs 11.3 mg·g–1 for trans-resveratrol) and up to five times more selectivity than standard resins. Despite such strong affinity, at low pH, the isotherm slope can decrease up to four times when compared to the XAD resins for the same ethanol content, making desorption easier. The included isotherm data is enough to model any chromatography dynamic simulation for the studied compounds.

“…Thus, in many studies, the plant sample was firstly extracted by ethanol-water solvent, and then the extract was condensed and lyophilized. The dry sample was re-dissolved in water to obtain the sample solution for resin adsorption [22,24]. The process is energy and labor intensive, and is not suitable for industrial application.…”

“…The resin adsorption-desorption process, an efficient and economical separation method in industrial practices, is widely used to purify targeted phytochemicals from plant, for instance, anthocyanins [20], rebaudioside A [21], resveratrol [22], brefeldin A [23], rosavin [24], glycyrrhizic acid [25], flavonoids [25][26][27], etc. Li et al had reviewed the applications of adsorptive macroporous resins for purification of various pharmacologically active natural products from plant sources [28].…”

“…MARs are more attractive than common adsorbents because of their favorable physical and chemical stabilities, large specific surface areas, high adsorption capacities, easy regeneration, and long service life [3]. Given these superior properties, MARs have been widely used in various fields [4][5][6][7]. Consequently, there are many types of MARs.…”
