COMPARISON OF POLYPHENOLIC COMPOSITION OF EXTRACTS FROM HONEYSUCKLE, CHOKEBERRIES AND GREEN TEA - A SHORT REPORT

The aim of the study was to compare the polyphenolic composition of extracts from different plant sources. Extracts from two new plants rich in polyphenols, i.e. chokeberries and honeysuckle, were compared with the well-investigated green tea polyphenols. All extracts obtained were characterised by a high content of polyphenols: green tea - 611 mg/g, honeysuckle - 633 mg/g and chokeberries - 714 mg/g. Honeysuckle and chokeberries extracts consisted mainly of anthocyanins (321.2 and 404.5 mg/g, respectively), whereas green tea extract contained mainly flavan-3-ols (587.9 mg/g).
