Resumen

Phytochemical screening of the content of total polyphenols, flavonoids, phenolic acids and anthocyanins in Bulgarian Carduus L. species was carried out. The plant materials (inflorescences) from all of the 14 species found in Bulgaria has been collected from natural habitats from different floristic regions, during the period 2011-2013. Chemical analysis of the specimens was carried out in accordance with 11 Russian and 7 European Pharmacopoeia. For some of the plant species the obtained results are the first published data about content of phenolic compounds. The content of flavonoids (1,8-3,2%) and total phenols(1,7-2,3%) was higher in comparison with this of phenolic acids (0,6-2,4%) and anthocyanins (0,5-1,5%). The highest content of total phenols and antocyanins was determined in the Carduus thracicus. The three species Carduus thoermeri, Carduus nutans and Carduus candicans ssp. globifer were characterized with the highest content of flavonoids. The highest content of phenolic acids was determined in the Carduus armatus.
