Total content of polyphenolic compounds expressed as chlorogenic acid was carried out by colorimetic method with Arnow's reagent. Reversed phase HPLC method was used for determination caffeoylquinic derivates calculated as chlorogenic acid, flavonids calculated as luteolin-7-O-glicoside in raw material samples and in addition cynarin in the sample of artichoke extract.
