| Description | Presented study is focused on the comparison of inherency and content of selected polyphenolic compounds in real samples of grape vine (Vitis vinifera) using capillary zone electrophoresis (CZE). The analyzed materials were milled grape seeds, stalks and leaves of two vine cultivars – Veltlínské zelené and Zweigeltrebe. In sample pretreatment, solid-phase extraction (SPE), supercritical fluid extraction (SFE) and/or liquid-liquid extraction (L-L) in dependence on the sample nature were used. The goal of this work was to compare the inherency and content of selected polyphenolic compounds in different plant samples of white and red vine cultivars. |
