Khalilov str. 23, hrovshan@hotmail.com 11Ministry of Science and Education Republic of Azerbaijan, Institute of Radiation Problems, Azerbaijan, Baku, B. Vahabzade St. 9, aygun.nasibova@mail.ru Using the Electron Paramagnetic Resonance (EPR) method, the influence of various radiation factors (ionizing gamma radiation, UV radiation, etc.) on living organisms (plants and animals) was studied [1, 2]. Identification of spectra recorded in a wide range of magnetic fields showed that, under the influence of radiation factors, signals characterizing magnetic iron oxide nanoparticles (g=2.32; ΔH=320 G) are recorded in them [3,4]. In recent years, we have been studying some medicinal plants of Azerbaijan using the EPR method. In most of them (rosemary (Salvia rosmarinus), rosehip (Rosa L.), etc.), the obtained spectra indicate the presence of nanophase crystalline magnetic particles (Fig. 1).
