Phenylboronic acid-functionalized gel resins for pH-controlled separation of catechol-containing flavonoids |
| 초록 |
Gel resins modified with different phenylboronic acid derivatives were prepared for separation of catechol-containing flavonoids. Carboxyl-carrying phenylboronic acids with different substituents were coupled to TentaGelTM resins. All the phenylboronic acid gel resins showed the pH-dependent adsorption and release of model catechol-containing flavonoid quercetin. Specific conjugation of quercetin to the resins was facilitated at higher pH in the range of pH 7-8.5, while hydrolytic release of quercetin was promoted at lower pH in the range of pH 4-6. Under optimal pH control, the resins exhibited equilibrium quercetin binding capacity up to 120 mg/g of resin and quantitative release of bound quercetin. In addition, the recyclability of 4MPBA-gel resin was confirmed by repeated binding and hydrolysis of quercetin with no significant loss of capacity during at least five cycles which shows a potential of PBA-gel as a tool for selective separation of catechol-containing flavonoids. |
