Sažetak
Phytochemical characterization of the Croatian endemic species Centaurea ragusina L. (Asteraceae) was carried out. Th e presence of polyphenols in above ground plant parts was proven by using chemical reactions of developing colored products and precipitates. Th e thin layer chromatography showed the presence of quercetin, rutin, and chlorogenic acid in the methanolic extract of C. ragusina. Quantitative analysis of total polyphenols (TP), tannins (T), fl avonoids (F), and phenolic acids (PA) was carried out using three diff erent spectrophotometric methods. Th e contents of analyzed polyphenolic compounds were as follows: 3.04±0.04% (TP), 0.36±0.04% (T), 0.25±0.00% (F), and 0.38±0.01% (PA). Th is phytochemical characterization is a contribution to the scientifi c study of Croatian endemic species and completes the existing knowledge about phytotherapeutic potential of C. ragusina, especially in relation to the content of bioactive polyphenolic substances.
