| Tartalmi kivonat: | Polyphenols are secondary metabolites of plants being involved in the protection against the solar ultraviolet radiation or pathogens aggression and are considered to posses beneficial effects on human health. The paper aims to determine the total concentration of polyphenolic compounds and anthocyanins in various samples such as wine, nectar, coffee and Noni juice, by UV-VIS spectrometery. The analysis of these compounds involves more aspects: determination of polyphenolic substances by the Folin-Ciocalteu method, determination of anthocyanins by the sodium bisulfite method for wine samples. |
