Free Radical Scavenging Activity of Infusions of Different Medicinal Plants for Use in Obstetrics

Abstract

An X-band (9.3 GHz) electron paramagnetic resonance (EPR) spectroscopy was used to examine the free radical scavenging activity of the following infusions, which were nonirradiated and exposed to UVA: root of Asparagus racemosus and herbs of Mitchella repens, Cnicus benedictus L., Galega officinalis L., and Eupatorium cannabinum L. The plant materials for obstetrics applications were chosen for analysis. The aims of these studies were to compare the free radical scavenging ability of the tested infusions and to determine the influence of UVA irradiation of the plant materials on interactions of these infusions with free radicals. Both the magnitude and kinetics of the interactions of the infusions with the model DPPH free radicals were examined. The ability to quench the free radicals for the examined plant infusions increases in the following order: Asparagus racemosus (root) < Mitchella repens (herb) < Cnicus benedictus L. (herb) < Galega officinalis L. (herb) < Eupatorium cannabinum L. (herb). The analyzed infusions differ in the kinetics of the interactions with free radicals. The fastest interactions with free radicals characterize the infusions of Galega officinalis L. herb and Eupatorium cannabinum L. herb. The infusion of Mitchella repens herb interacts with free radicals in the slowest way. UVA radiation reduces the antioxidant interactions of all tested infusions, especially the infusion of Eupatorium cannabinum L. herb, which should be protected against UVA radiation during storage. The weakest decrease of free radical scavenging activity was observed for the infusion of the root of Asparagus racemosus exposed to UVA radiation. UVA radiation affected the speed of the free radical interactions of the infusions, depending on the type of plant materials. EPR spectroscopy is useful to examine the free radical scavenging activity of plant infusions, which is helpful to find effective antioxidants for applications in obstetrics and their optimal storage conditions.

Effects of dietary pretreated Chinese herbal medicine supplementation on production performance, egg quality, uterine histopathological changes, and antioxidant capacity in late-phase laying hens

“…Oxidative stress may come from either an excess of free radical generation or a breakdown of antioxidant defense systems (Torun et al, 2009). It has been reported that some herbs possess strong radical-scavenging ability (Jarco et al, 2021). In the current study, PCHM was added to the diet to effectively improve the free-radical scavenging capacity and reduce the content of MDA in liver, magnum, and uterus.…”

A Mini Review: The Application of Eupatorium Plants as Potential Cosmetic Ingredients

“…In addition, UVA radiation may increase the risk of skin cancer [111]. Jarco et al [112] declared that UVA radiation reduces the antioxidant interactions of all of the investigated infusions, particularly the infusion of the E. cannabinum L. herb, which should be protected from UVA radiation during storage. Table 2 presents the potency of the radical scavenging activity from Eupatorium species.…”

Antioxidant Effect of Chrysanthemum morifolium (Chuju) Extract on H2O2-Treated L-O2 Cells as Revealed by LC/MS-Based Metabolic Profiling

“…A lot of natural compounds including alkaloids, phenolics, and terpenes in chrysanthemum have been identified as antioxidants [ 6 ]. For them, the predominant effects may involve the activation of Nrf2-related antioxidant pathways and scavenging of free radicals [ 7 , 8 , 9 ]. However, researchers found that the biological activities of natural extracts are much higher than those of single bioactive molecules due to the interaction between molecules at pharmacodynamic and pharmacokinetic levels, suggesting that the synergistic effect between multiple compounds cannot be overlooked [ 10 ].…”
