The quantitative and qualitative analyses of phenolic acids present in flowers and leaves of Trifolium repens and Trifolium pratense were carried out. The contents of phenolic acids expressed as caffeic acid were determined by the spectroscopic method described in FP VI. The results showed that the level of phenolic acids in flowers and leaves of I pratense (1.22%, 0.65%, respectively) was twice as high as in flowers and leaves of T. repens (0.54%, 0.37%, respectively). Identification of phenolic acids was performed by chromatographic methods: 2D-PC, 2D-TLC and RP-HPLC. In all the studied extracts the presence of 9-10 components was detected, and the following acids were identified: p-hydroxybenzoic, salicylic, protocatechuic, gentisic, p-coumaric, caffeic and ferulic. In the extracts obtained from flowers of both species p-hydroxybenzoic and salicylic acids were the main compounds. In the extract obtained from T. repens leaves caffeic acid was the dominating compound, whereas caffeic and salicylic acids in leaves of T. pratense.
