Zusammenfassung

A micellar electrokinetic chromatographic (MEKC) method has been established for the identification and determination of acid-catalyzed proanthocyanidin cleavage products in the presence of phloroglucinol. Using fused-silica capillaries (50/57 cm, 22 kV) with phosphate buffer containing sodium dodecyl sulfate as the surfactant and β-cyclodextrin as modifier, structurally similar phloroglucinol adducts and flavan-3-ols were fully separated.
