Abstract:
The kasumba turate plant (Carthamus tinctorius (L.) has the potential as a free antiradical. Free antiradical compounds in kasumba turate plants come from secondary metabolites produced by endophytic compounds known as endophytic fungi. Kasumba turate contains phenolic compounds and carotenoids that have antioxidant activity. This study aims to obtain isolates of endophytic fungi in kasumba turate (Carthamus tinctorius (L.) plants that can act as free antiradicals by KLT-Autography method. Five isolates IFDK 01, IFDK 02, IFDK 03, IFDK 04, and IFDK 05 were obtained. After testing the antioxidan

Abstract:
The usage of antiradical agents is pivotal for suppressing the negative effects of free radicals on human health. Curcumin, a well-known natural antiradical agent, suffers from its low stability and high price, thus, limiting its potential in real applications. In this work, we carried out the impregnation of encapsulated curcumin from Aceh curcuma source on commercial titanium dioxide. The isolation of curcumin was performed using a simple maceration method, while the encapsulation process was done employing carboxymethylcellulose and maltodextrin to give ethanol-curcumin and triacetin-curcum

Compounds so tested exhibited antioxidant and antiradical properties to varying degrees. Methyl ferulate showed the strongest antioxidant activity, whereas the parent phenolic acid was the most active ferulate to scavenge the DPPH radical (DPPH&lt;sup&gt;&amp;middot;&lt;/sup&gt;).

Abstract:
In this study, the antioxidant and antiradical capacities of anthraquinones from Rubia cordifolia Linn were determined using the DFT method. The thermodynamically most favorable reaction pathways of antioxidant mechanisms were defined, as well as the most favorable antiradical reaction mechanisms for the deactivation of methylperoxyl and methoxy radicals. The calculations were done in the gas phase. HAT is thermodynamically the most favorable mechanism of antioxidant action of the studied anthraquinones, while the most probable mechanism of deactivation of methylperoxyl and methoxy radicals is

Abstract:
Origanum dictamnus, also known as Dittany of Crete, is an aromatic herb from the Lamiaceae family, valued for its medicinal properties. This study investigates the antioxidant potential of Origanum dictamnus extracts prepared using different solvents (water, ethanol, 50% ethanol, and methanol) and their subsequent encapsulation into soy lecithin liposomes. The extracts were evaluated for their antiradical scavenging activities against DPPH and •OH radicals using electron paramagnetic resonance (EPR) spectroscopy. Methanol and 50% ethanol extracts demonstrated the highest antioxidant potential

Abstract:
Honey powders could be an innovative and attractive substitutes to liquid honey. The production of honey powders would allow to expand honey’s usage in food industry, cosmetics and pharmaceutics. In this research, freeze drying method was performed to obtain honey powder samples. Overall, 4 different formulations were prepared to obtain the powder samples. The aim of the research was to determine the total phenolic content and antiradical activity of the freeze-dried honey powder samples by spectrophotometric method. The content of total phenolics in the samples ranged from 92 to 146 mg GAE 10

In this study, the mechanisms of antiradical activity of the previously synthesized 4,7- dihydroxycoumarin derivative:(E)-3-(1-((4-hydroxyphenyl)amino)ethylidene)-2,4- dioxochroman-7-yl acetate (A-4OH) according to the series of chloromethylperoxy radicals: OOCH2Cl (chloromethylperoxy), OOCHCl2 (dichloromethylperoxy) and OOCCl3 (trichloromethyl peroxy) were investigated. To assess the mechanisms of antiradical activity of A-4OH against chloromethylperoxy radicals, the following mechanistic pathways were examined: Hydrogen Atom Transfer (HAT), Single-Electron Transfer followed by Proton Transfe

Abstract:
We have demonstrated that dinitrosyl iron complexes (DNICs) eliminate free radicals formed during the interaction of hemoproteins with tert-butyl hydroperoxide, as well as during the co-oxidation of lipids and glucose. Thus, DNICs act as antioxidants under conditions simulating different types of oxidative stress.
