Tam Çiçeklenme Döneminde Yapraktan Uygulanan Kitosan, Demir Oksit ve Kitosanla Kaplanmış Demir Oksit Nanopartiküllerinin Farklı Konsantrasyonlarının Hypericum triquetrifolium Turra.’nın İkincil Metabolitleri Üzerine Etkileri

Hypericum triquetrifolium Turra. (Hypericaceae) is one of the important medicinal plants. This herb used in Turkish folk medicine for its antidepressant, anthelmintic and antiseptic effects. extracts have an commercial value pharmaceutical industry. Therefore, studies to increase amount secondary metabolites it contains are becoming widespread. Elicitors biological non-biological factors that can affect synthesis In recent years, nanoelicitors been active ingredients. this study, stimulate biologically compounds H. triquetrifolium; chitosan, iron oxide chitosan-coated nanoparticles concentrations 0 (control), 50, 75, 100 150 ppm were sprayed on leaves during full bloom. LC-MS/MS analysis showed application chitosan increased flavonol (hyperocyte quercitrin) naphthodianthrons (pseudohypericin hypericin) triquetrifolium. 50 nanoparticle hyperocyte, quercitrin pseudohypericin; 75 hyperforin. The resulted all except hypericin. coated with also as elicitors improve chemical properties oxide. series, was effective amounts quercitrine, kaempferol pseudohypericin. concentration group quercitrin.
