Comparison of some anthocyanins sorption upon convenient reversed-phase and styrene-divinylbenzene copolymer
Abstract
The comparison of 3-glucosides of six common anthocyanidins (pelargonidin, cyanidin, delphinidin,
petunudin, peonidin and malvidin) chromatographic behavior upon two types of reversed-phases
(conventional C18 as well as copolymer of styrene-divinylbenzene) was investigated. On the basis of
resolution maps and standard enthalpy of solute transfer from mobile phase onto stationary phase the
common features and the differences were elucidated. In spite of the discrepancies it was established that
polymer sorbents may be used for anthocyanins determination in severe conditions that are not well suitable
for conventional reversed-phases.
