The Effects of Different Concentrations of Foliar Applied Chitosan, Iron Oxide and Chitosan-Coated Iron Oxide Nanoparticles on the Secondary Metabolites of Hypericum triquetrifolium Turra. During Full Bloom

Abstract

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