Prooxidant–antioxidant system and change of alkaloids level in jimson weed (Datura stramonium L.) under the influence of static magnetic field

Abstract

The effect of magnetic radiation on the prooxidant-antioxidant system and alkaloids level in Jimson weed (Datura stramonium L.) have never been studied and reported before. The objective of this research was to study the influence of static magnetic field on the homeostasis and alkaloids level in D. stramonium. The level of (thio) barbituric acids active products, superoxide dismutase and catalase activity in D. stramonium seedlings under the influence of static magnetic field with the intensity of 3 mT and 10 mT at two exposure times, 30 min and 22 hours, was studied. Under these conditions, the level of alkaloids in the extract from leaves and stems of germs was determined by chromatographic analysis. An increased level of lipid peroxidation products, the activity of superoxide dismutase and catalase in seedlings under the long-term effect of magnetic field were observed. The level of scopolamine alkaloid depended on the duration of exposure to the static magnetic field; however, this factor did not effect the atropine level. The obtained experimental data was confirmed by the results of the analysis of variance.
