<p>Hemijska karakterizacija ekstrakata <em>T. pratense </em>L. određena je LC-MS-MS, a etarskih ulja GC-MS analizom, pri čemu je identifikovano više bioaktivnih jedinjenja. Spektrofotometrijskim metodama ispitan je antioksidantni potencijal ekstrakata i etarskih ulja. Hepatoprotektivni efekat određen je na homogenatu i hemolizatu jetre laboratorijskih miševa. Budući da ova biljka ima visok sadržaj izoflavona, određena je <br />estrogena, antiestrogena aktivnost, kao i citotoksičnost ekstrakata. Antimikrobna <br />aktivnosta ekstrakata i etarskih ulja ispitana je na šest bakterijskih sojeva. Ekstrakti i etarska ulja su bili umereno aktivni u pogledu bioloških aktivnosti, osim u slučaju antimikrobne aktivnosti koju nije pokazao nijedan ispitivani uzorak.</p> / <p>The chemical characterization of <em>T. pratense</em> extracts was determined by LC-MS-MS, and the essential oils of the GC-MS analysis, wherein the various bioactive compounds were identified. Antioxidant potential of extracts and essential oils was tested by spectrophotometric methods. Hepatoprotective effect was determined in haemolysate and liver homogenate of laboratory mice. Estrogen, antiestrogen activity, as well as the cytotoxicity of the extracts were determined due to the high content of isoflavones. Antimicrobial activity of extracts and essential oils was investigatied on six bacterial strains. Essential oils and extracts were moderately active in terms of biological activity, except in the case of antimicrobial activity where none of the extracts were active against tested bacterial strains.</p>
