Abstract

In the current study, the fractionation and isolation of polyphenols from Aronia melanocarpa has been performed with two different chromatographic techniques on a large scale. On the one hand, the fractionation of polyphenols such as anthocyanins, phenolic acids, quercetin–glycosides and flavanons from A. melanocarpa pomace was done by high-speed countercurrent chromatography and low-speed rotary countercurrent chromatography. On the other hand, the preseparation of A. melanocarpa extracts from pomace and juice in an anthocyanin and a co-pigment fraction was carried out by membrane chromatography after removing the polymeric procyanidins by precipitation with ethanol. Afterward, the separation and isolation of anthocyanins and co-pigments were done by preparative countercurrent chromatography. Purity control and identification of the isolated compounds were made by HPLC–PDA, HPLC–ESI-MS

ⁿ and

¹H- as well as

¹³C-NMR spectroscopy. Various compounds, e.g., chlorogenic acids, isorhamnetin-, apigenin-, luteolin- and taxifolin-derivatives, are described for A. melanocarpa for the first time.
