I hypothesized in April, 2020 that caffeic acid, which is pharmacologically active compound of many medicinal herbs such as Echinacea purpurea and Sambucus Formosana Nakai, might be a potent molecule for the treatment of COVID-19, especially if pared with Fe3+ ions (caffeic acid Fe3+ chelate) or other ions (MoO42- and PO43- chelates), because antiviral

Abstract The instability of anthocyanins limits their application as natural food colorants. This study aimed to enhance the stability of anthocyanins extracted from Hibiscus sabdariffa through copigmentation with protein nanofibrils produced from pea, rice, gluten and whey isolates. Linear and curly nanofibril structures were prepared and incorporated

Caffeic acid is a central metabolite in the fungal bioluminescence pathway. We identified and characterized caffeylpyruvate hydrolase from Neonothopanus gardneri (ngarCPH) and demonstrate its ability to hydrolyze fungal oxyluciferin into caffeic and pyruvic acids, confirming a complete and self‐sustained fungal bioluminescence cycle.

Determination of Phenolic Acids in Sugarcane Vinasse by HPLC with Pulse Amperometry
A reversed-phase liquid chromatographic separation with pulsed amperometric detection of phenolic acids at a glassy carbon electrode is described. Chromatographic separation was carried out in isocratic conditions using 0.20 mol·L−1 acetic acid (pH 5.0 ...

Hulless barley resists the newly identified sheath rot disease caused by the necrotrophic fungal pathogen Dactylobotrys graminicola by releasing coniferyl aldehyde, a natural compound that disrupts energy production in the fungus. ABSTRACT Dactylobotrys graminicola (Dgr), a necrotrophic fungal pathogen, has recently been identified as the causative ...

ABSTRACT Sugar crops, including but not limited to sugarcane, sugar beet, sweet sorghum and stevia, are major sources of sugar production in the world. However, conventional breeding approaches, limited by long breeding cycles, low efficiency and restricted capacity to improve complex traits in sugar crops, are increasingly insufficient to address the ...

COMPARATIVE STUDY OF POLYPHENOLS FROM PROPOLIS EXTRACTS OF DIFFERENT ORIGIN
The propolis, a resinous substance produced by bees, was used from ancient times as one of the best general panaceea. The main active compounds known in propolis are the phenolic acids and flavonoids from the class of polyphenols.

Antioxidant Scavenging of the Superoxide Radical by Yerba Mate (Ilex paraguariensis) and Black Tea (Camellia sinensis) Plus Caffeic and Chlorogenic Acids, as Shown via DFT and Hydrodynamic Voltammetry [PDF]
We describe the antioxidant capability of scavenging the superoxide radical of several tea and yerba mate samples using rotating ring–disk electrochemistry (RRDE).
