This study aimed to determine the antioxidant properties of sulfate monoesters ferulic, caffeic, dihydroferulic and dihydrocaffeic acids, main metabolites chlorogenic acids. These compounds are not commercially available, so they were synthesized in laboratory. The LC-MS/MS analysis allowed for full characterization these derivatives, which has made them reliable standards further research. Pur...

The aim of this work is to investigate the synergistic antibacterial effect of phenolic compound mixtures against Listeria monocytogenes in brain heart infusion (BHI) medium, and to select the best mixture for testing their antibacterial activity in a meat model system. In BHI medium, the most effective mixtures were those of gallic and caffeic acids, gallic and protocatechuic acids, and rutin ...

INTRODUCTION Proximal spinal muscular atrophy (SMA) is a common autosomal recessively inherited neuromuscular disorder. It is caused by homozygous absence of the survival motor neuron 1 (SMN1) gene. SMN2, which modulates the severity of the disease, represents a major target for therapy. The aim of this study was to investigate whether SMN2 expression can be increased by caffeic acid, chlorogen...

Ready-to-eat meats are susceptible to pathogenic contamination during their production, distribution, and sale. This study evaluated the antimicrobial effects of two phenolic acids (caffeic ferulic acids) against foodborne pathogens in cold-cut meat at low-temperature conditions. The individual combined antibacterial activities caffeic Escherichia coli O157:H7 ATCC 43888 Listeria monocytogenes ...

salicylic acid (sa) and methyl jasmonate (meja) as phytohormone regulate synthesis of secondary metabolites in a wide range of plant species by accumulation of phenylalanine ammonia lyase enzyme (pal) and accelerate the production of oxygen free radicals, protein kinase, proline and nitrite oxide content. to study the effect of these compounds on synthesis of secondary metabolites, in two separ...

A rapid and sensitive high-performance liquid chromatographic (HPLC) method was developed for the simultaneous separation and determination of chlorogenic acid, caffeic acid, alantolactone and isoalantolactone in Inula helenium. The HPLC separation was performed on an Elite Hypersil C18 column (200 × 4.6 mm i.d., 5 µm particle size) with a gradient elution of solvent A (acetonitrile) and solven...

The objective of this study was to determine the effect on fatty acid composition of heating olive and sunflower oils with selected natural and synthetic antioxidants. The antioxidants investigated were quercetin, caffeic acid, protocatechuic acid, and butylated hydroxyanisole (BHA), each at concentrations of 0.02, 0.04, and 0.06%. Oils with no added antioxidants were also heated. After heating...
