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).

Celem pracy było porównanie zawartości związków polifenoli zawartych w ekstraktach uzyskanych z różnych surowców roślinnych. Porównano ekstrakty uzyskane z nowych bogatych w polifenole owoców aronii oraz jagody kamczackiej z dobrze już poznanymi polifenolami herbaty zielonej. Wszystkie uzyskane ekstrakty charakteryzowały się wysoką zawartością związków fenolowych ogółem; herbata zielona 611, jagoda kamczacka 633 i aronia 714 mg/g. Ekstrakty z aronii i jagody kamczackiej zawierały głównie antocyjany (404,5 i 321,5 mg/g, odpowiednio. Flawan- -3-ole (katechiny) dominowały w składzie ekstraktu z herbaty (epikatechina 262,5 oraz galusan epigalokatechiny 276,8 mg/g).
