(Asteraceae) %A Tadeusz Krzaczek %A Monika Gawro¨˝ska-Grzywacz %J Acta Societatis Botanicorum Poloniae %D 2006 %I Polish Botanical Society %R 10.5586/asbp.2006.025 %X The analysis of the fractions of free and bound, liberated by hydrolysis, phenolic acids in the inflorescences and rhizomes with roots of Hieracium pilosella L. was conducted by 2D-TLC and RP-HPLC methods. In the inflorescences fourteen phenolic acids were found: chlorogenic, gallic, protocatechuic, homoprotocatechuic, caffeic, gentisic, p-hydroxyphenylacetic, p-hydroxybenzoic, m-hydroxybenzoic, p-coumaric, syringic, vanillic, ferulic and salicylic. In the rhizomes with roots nine phenolic acids were identified: chlorogenic, gallic, homoprotocatechuic, caffeic, gentisic, p- hydroxyphenylacetic, p-hydroxybenzoic, syringic and vanillic. By means of the RP-HPLC method the contents of major acids were estimated which ranged from 0.01 mg% up to 139.50 mg%. Caffeic acid is the remarkably dominating constituent of both plant materials. Phenolic compounds may contribute to invasiveness and medicinal properties of this species. %K Hieracium pilosella L. %K phenolic acids %K SPE %K 2D-TLC %K RP-HPLC %U http://pbsociety.org.pl/journals/index.php/asbp/article/view/535
