Fenolické látky vo vybraných rastlinných druhoch

This diploma thesis deals with the analysis of phenolic compounds such as phenolic acids and flavonoids in selected plants, such as ribwort plantain (Plantago lanceolata L.) in which the content of chlorogenic acid, caffeic acid, verbascoside, ferulic acid, rutin and quercetin was monitored. The content of chlorogenic acid, coffee acid, routine, hyperoside, isoquercitroside, tiliroside, quercetin and kaempferol was monitored in small-leaved lime (Tilia cordata Mill.) In addition, the content of chlorogenic acid, caffeic acid, coumaric acid, rutin, hyperoside, isoquercitroside, quercetin and kaempferol was monitored in marigold (Calendula officinalis L.). Also the content of chlorogenic acid, coffee acid, rutin, hyperoside, isoquercitroside, quercetin and kaempferol was monitored in elderberry (Sambucus nigra L.). Similarly the extraction of phenolic compounds from these plants was carried out and subsequently subjected to chromatographic analysis on a UPLC liquid chromatograph with a PDA detector at the Research Institute of Brewing and Malting, Plc
