- Results indicated that all tested herbs possess antioxidant properties, with a strong positive correlation between antioxidant activity and total phenolic content.
Article Abstract
Antioxidant properties of selected herbs were investigated using electron paramagnetic resonance (EPR) spectroscopy. This was possible by measuring changes in the intensity of the EPR spectrum that resulted from the interaction of the stable radical 1,1-diphenyl-2-picrylhydrazyl with antioxidants found in herbal samples. Moreover, the total phenolic content (TPC) was measured using UV-Vis spectroscopy. The values of trolox equivalent antioxidant capacity were in the range of 10.95 to 505.95 μmol Trolox/1 g of dry weight of sample. TPC values were in the range of 3.38 to 63.13 mg of gallic acid/1 g of dry weight. The results showed that all of the investigated herbs exhibit antioxidant properties. A positive and significant correlation between antioxidant activity and total phenolic content was observed. The studied herbs could be a good source of natural antioxidants.

Pulsed dipolar electron paramagnetic resonance (PD-EPR) measurement is a powerful technique for characterizing the interactions and conformational changes of biomolecules. The extraction of these distance restraints from PD-EPR experiments relies on manipulation of spin-spin pairs. The orthogonal spin labeling approach offers unique advantages by providing multiple distances between different spin-spin pairs.

Monoterpenes (MTs), the major constituents of plant essential oils, cover a broad spectrum of biological activities through their interaction with biomembranes. MTs are highly hydrophobic substances with a net electrical dipole, but are not clearly amphipathic. As a result, they aggregate at increasing concentrations in aqueous media, and in membrane environments their behavior changes from dynamics modulators to disruptors.

This article investigates the influence of dopant molecules on the structural and dynamic properties of lipid bilayers in liposomes, with a focus on the effects of dopant concentration, size, and introduced electric charge. Experimental studies were performed using electron paramagnetic resonance (EPR) spectroscopy with spin probes, complemented by Monte Carlo simulations. Liposomes, formed via lecithin sonication, were doped with compounds of varying concentrations and analyzed using EPR spectroscopy to assess changes in membrane rigidity.

The bacterium responsible for Lyme disease, , accumulates high levels of manganese without iron and possesses a polyploid genome, characteristics suggesting potential extreme resistance to radiation. Contrary to expectations, we report that wild-type B31 cells are radiosensitive, with a gamma-radiation survival limit for 10 wild-type cells of <1 kGy. Thus, we explored radiosensitivity through electron paramagnetic resonance (EPR) spectroscopy by quantitating the fraction of Mn present as antioxidant Mn metabolite complexes (H-Mn).

Understanding the environmental fate of chemical herbicides is crucial to sustainable agriculture. Due to their joint-use with nitrogen fertilizers, their residues often coexist with NO in agricultural drainages. In this study, tribenuron-methyl was used as a model to evaluate the role of NO in the phototransformation of chemical herbicides, which was characterized by a two-stage process.
