Abstract/OtherAbstract:
A molecularly imprinted polymer was prepared using E-resveratrol as template and was evaluated for multi-component multi-class analysis of polyphenolic compounds in complex matrices such as natural and alcoholic beverages. Chromatographic evaluation of the polymer exhibited high selectivity for E-resveratrol and its structural analogues as quercetin and other flavonoids. An analytical procedure based on Molecularly imprinted solid phase extraction (MISPE) and high performance liquid chromatography coupled to UV detector was developed and validated for determination of (E)-resveratrol and quercetin in wine and fruit juice samples. Specific binding capacity of the MIP was estimated as 80 μg g-1 polymer by the cartridge test. MISPE sample pretreatment allows an excellent sample clean up enormously decreasing the number of co-extracted potentially interfering compounds. Under the described conditions, by extracting 2 mL samples a clean extract is obtained and E-resveratrol and quercetin could be easily identified at concentration levels of respectively 1.5 and 7.0 μg L-1 level. Keywords: molecularly imprinted polymer, solid phase extraction, flavonoids, resveratrol, quercetin, wine, red fruits juice, lingonberry.
