Of particular interest were the hydroxycinnamic acids (HCAs) and derivatives in beer extracts because of their antioxidant properties. Main HCAs and a key derivative of ferulic acid, 4-vinylguaiacol (4-VG), were identified in beer extracts by high performance liquid chromatography (HPLC). ...
4.3. Electrochemical Behaviour of Hydroxycinnamic Acids and Derivatives Considering that hydroxycinnamic acids are antioxidants compounds by excellence, electrochemical techniques can be powerful tools for the study of reaction mechanisms involving electron transfer and afford complementary information. The main st...
Recently hydroxycinnamic acids have received increased attention due to their ability to form photo-responsive materials and also their natural abundance providing sustainable origins. However, of this class, o-hydroxycinnamic acid has been underexplored as a raw material for the development of stimuli-re...
Hydroxycinnamic acidsMechanism of oxidation of dopaMesophyll cell protoplastsVacuolar peroxidaseVicia fabaMechanisms of oxidation of 3,4-dihydroxyphenylalanine (dopa) in leaves of Vicia faba have not yet been elucidated in details. The author hypothesized its oxidation by radicals of hydroxycinnamic acid ...

In addition, increases of damaged cellular macromolecules such as nucleic acids, proteins, lipids has been observed in AD brains. These findings support reactive oxygen species (ROS) plays a pivotal role in AD onset and progression. Therefore, antioxidants should be beneficial therapeutic tools in ...
Plants produce a wide array of secondary metabolites that play important roles in their interactions with their biotic and abiotic environments [1]. Hydroxycinnamates or phenylpropanoids (C6-C3 compounds), that is, ferulic, coumaric, caffeic, and sinapic acids, and their derivatives, are among the...
para-Coumaric or para-hydroxycinnamic acids have been described as inhibitors of melanin production in numerous studies. However, these substances do not make it possible to obtain significant inhibitory effects on melanin synthesis. This excessively weak activity does not make it possible to obtain str...
