In this work the phenolic acids in the methanol extract from the flowering herbs of Cirsium vulgare (Savi) Ten. growing in Poland were isolated and identified. The samples containing free phenolic acids and those released after acid and alkaline hydrolyses were investigated by 2D TLC on cellulose. After purification by SPE, samples were also analyzed by RP-HPLC. Six phenolic acids such as gallic, protokatechuic, gentisic, hydrobenzoic, vanillic and caffeic acids were detected in the fraction of free phenolic acids of the methanol extract, irrespectively of the method used.

Simultaneous identification of eight phenolic acids (gallic, protocatechuic, chlorogenic, p-hydroxybenzoic, vanillic, caffeic, p-coumaric and ferulic) and three flavonoid aglycones (Iuteolin, kaempferol and apigenin) in Et20-fractions of inflorescences and leaves of five species of Cirsium genus - C. arvense, C. oleraceum, C. palustre, C. rivulare and C. vulgare was carried out by HPLC method. Phenolic acids and flavonoids were analyzed also in terms of quantity. The contents of phenolic acids, expressed as cafifeic acid, determined by the spectroscopic method with Arnov's reagent, were higher in leaves than in flower heads of all investigated species and amounted from 0.15% in C. vulgare inflorescences to 1.31% in C. palustre leaves. The flavonoid contents, indicated by Christ-Miiller's method ranged from 16 mg • 100g1 per dry source in C. arvense and C. palustre inflorescences to 70 mg • 100g ' in C. oleroceum Leaves.
