Seven derivatives of plant-derived hydroxybenzoic acid (HBA)—including 2,3-dihydroxybenzoic (2,3-DHB, pyrocatechuic), 2,4-dihydroxybenzoic (2,4-DHB, β-resorcylic), 2,5-dihydroxybenzoic (2,5-DHB, gentisic), 2,6-dihydroxybenzoic (2,6-DHB, γ-resorcylic acid), 3,4-dihydroxybenzoic (3,4-DHB, protocatechuic), 3,5-dihydroxybenzoic (3,5-DHB, α-resorcylic), and 3,4,5-trihydroxybenzoic (3,4,5-THB, gallic) acids—were studied for their structural biological properties. Anti-/pro-oxidant properties were...
Exposure of sunflower and maize plants to increasing concentrations lithium (0-50 mg Li dm(-3)) in a nutrient solution induced changes biomass, leaf area photosynthetic pigment accumulation, as well levels lipid peroxidation. The highest applied dose (50 evoked significant reduction the shoot biomass for both examined species, necrotic spots plants. An enrichment with 5-50 dm(-3) did not significantly affect chlorophylls b carotenoid content However, maize, decrease all under used...
Abstract In this study the peels of ecologically grown apple ( Malus domestica ) cultivars: Gold Milenium (a new scab‐resistant variety) and Papierowka (Papirovka; an old, sensitive to scab were examined for their composition (phenolic compounds, triterpenoids, simple organic acids, macro-, microelements, reducing sugars, l -ascorbic acid), pro- antioxidant properties as well application in reduction oxidative stress cultured human skin fibroblast. The higher content phenolic compounds...
For many years, metal–flavonoid complexes have been widely studied as a part of drug discovery programs, but in the last decade their importance materials science has increased significantly. A deeper understanding role metal ions and flavonoids constructing simple more advanced hybrid networks will facilitate assembly with tailored architecture functionality. In this Review, we highlight most essential data on systems, presenting promising alternative design inorganic–organic materials. We...
The evaluation of the electronic charge distribution in metal complexes enables more precise interpretation mechanism by which particular ions affect biochemical properties ligands [J. Inorg. Biochem. 99 (2005), 1407–1423, J. Mol. Struct. 919 (2009), 284–289]. In this paper we investigated influence alkali cations (lithium, sodium, potassium, rubidium and cesium) on structure p -coumaric acid ( -CA). It allowed to observe systematic changes spectra depending position element periodic table....
Lithium (Li) is a trace element that essential in the human diet due to its importance for health and proper functioning of an organism. However, biological activity this metal crop plants, which are primary dietary sources Li, still poorly understood. The aim presented study was comparatively analyse two Li chemical forms on growth, as well L-ascorbic acid content, accumulation translocation butterhead lettuce (Lactuca sativa L. var. capitata) cv. Justyna. plants were grown nutrient...
Skin is the largest organ in human body, and which protects organism against unfavorable external factors e.g., chemicals, environment pollutants, allergens, microorganisms, it plays a crucial role maintaining general homeostasis. It also an important target of oxidative stress due to activity oxygen reactive species (ROS), are constantly generated fibroblasts response exogenous or endogenous prooxidant agents. An example such compound with proved Doxorubicin (DOX), effective anticancer...
The structure of the Zn(II) complex 5-caffeoylquinic acid (chlorogenic acid, 5-CQA) and type interaction between cation ligand were studied by means various experimental theoretical methods, i.e., electronic absorption spectroscopy UV/Vis, infrared FT-IR, elemental, thermogravimetric density functional theory (DFT) calculations at B3LYP/6-31G(d) level. DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), FRAP (ferric reducing antioxidant power),...
Abstract In the study cold-pressed, natural (unfiltered, unrefined) vegetable oils: hemp and milk thistle seed oils were tested for their chemical composition antioxidant properties. The physico-chemical parameters, content of saturated unsaturated fatty acids determined. Solid phase extraction simple with use methanol, ethanol, 80% ethanol used to obtain extracts analysis activity phenolic compounds in oils. was studied by means high-performance liquid chromatography (HPLC–DAD)...
Caffeic acid (CFA) is one of the various natural antioxidants and chemoprotective agents occurring in human diet. In addition, its metal complexes play fundamental roles biological systems. Nevertheless, research on properties CFA with lanthanide metals very scarce, little to no chemical or information known about these particular Most their properties, including activity environmental impact, strictly depend structure, stability, solution behaviour. this work, a multi-analytical-technique...
Chloroderivatives of phenoxyacetic acid are a group compounds commonly used as plant protection products. Differences in the molecular structure these related to varying substitution and number chlorine atoms aromatic ring. Different structures may affect activity compounds, their physicochemical properties, well toxicity biological effects. A 6 chemical derived from was tested. The analysed using spectroscopic methods (FTIR, FTRaman, UV-VIS, 1HNMR, 13CNMR) quantum computational (DFT)....

The Na(I), Zn(II) and Ni(II) complexes with quercetin have been synthesized. composition of these compounds was established by means elemental thermogravimetric analyses. To study the molecular structure synthesized compounds, many miscellaneous analytical methods, which complement one another, were used: infrared (FT-IR), Raman (FT-Raman) electronic absorption UV/VIS spectroscopy. For studying cytotoxic genotoxic activity bioreporter strain Escherichia coli K-12 recA::gfpmut2 has used.
The research was conducted in the "logical series" of seven ligands: chromone, flavone, 3-hydroxyflavone, 3,7-dihydroxyflavone, galangin, kaempferol and quercetin. Each subsequent ligand differs from previous one, among others by an additional hydroxyl group. studied chromone derivatives are plant secondary metabolites which play important role growth, reproduction, resistance to pathogens. They food ingredients with valuable pro-health properties. studies relationships between their...
