| description | Phenolic compounds have a number of benefits to human health and can be used as preventive compounds for the development of some chronic diseases. <i>Mentha</i> plants are not only a good source of essential oils, but also contain significant levels of wide range of phenolic compounds. The aim of this research was to investigate the possibility to increase phenols content in <i>Mentha</i> plants under the foliar application with L-phenylalanine, L-tryptophan, L-tyrosine at two concentrations (100 mg L<sup>−1</sup> and 200 mg L<sup>−1</sup>) and to create preconditions for using this plant for even more diverse purposes. Quantitative and qualitative analyses of phenols in mints were performed by HPLC method. Foliar application of amino acids increased the total phenol content from 1.22 to 3.51 times depending on the treatment and mint variety. The most pronounced foliar application to total phenols content was tryptophane especially in <i>Mentha piperita</i> “Swiss”. <i>Mentha piperita</i> “Swiss” was affected most by foliar application and the amount of total phenolic acids depending on the treatment ranged from 159.25 to 664.03 mg 100 g<sup>−1</sup> (DW), respectively, non-sprayed and sprayed with tryptophane 100 mg L<sup>−1</sup>. Our results suggest that the biophenol content varies according to such factors as foliar application and variety, and every single mint variety has individual response to different applications of amino acids. |
