Primula veris L. (Cowslip primrose) is a species of flowering plant in the family Primulaceae. Usually, flowers and leaves from cowslip primrose are used for making sedative tea. The cowslip roots are also used in the treatment of respiratory tract problems, as an expectorant. In the present study we compared flowers, leaves and roots from Primula veris harvested in two different locations in the Western part of Romania (Julita and Nadas). In order to evaluate the phenolic content, antioxidant activity and the chemical composition, the ethanolic extracts have been obtained by maceration for 7 days. The results obtained indicated that ethanolic extracts of Primula veris presented high phenolic content that ranged between 131 to 168 mg GAE/L for roots, 136 to 159 mg GAE/L for leaves and 133 to 219 mg GAE/L for flowers. Remarkable percent of inhibition of DPPH has been obtained for all plants parts (as roots 16.4-23.2%, leaves 16.0-17% and flowers 14.9-24.7 %.) The following compounds have been quantified in all different plant parts: gallic acid, quercetin and kaempferol using Ultra-High Performance Liquid Chromatography (UHPLC).
