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.
