Chlorogenic acid possessed a weak caffeine-like psychostimulant property when assessed for its effect on spontaneous locomotor activity in mice. In the evaluation of the effects for the major metabolites of chlorogenic acid which were detected upon incubation with rat feces and/or excreted in urine after oral administration to rats, caffeic and m-coumaric acids were found to be the principal ac...

In this study, we identified and determined the content of phenolic compounds in Lilium candidum adventitious bulbs formed vitro. HPLC analysis revealed presence four acids: chlorogenic, caffeic, p-coumaric, ferulic acid. Phenolic acid was assessed vitro on media supplemented with zinc oxide nanoparticles (ZnO NPs at 25, 50, 75 mg/L) under fluorescent light (FL) or darkness (D). The second expe...

NMR methods can be used to delineate detailed structural and regiochemical information on the plant cell wall and elucidate biochemical incorporation pathways. Maize lignin isolated in high yield from rind tissue of stem internodes contained high amounts of esterified p-coumaric acid. Available literature indicated that acylation of the lignin by p-coumaric acid was at the αor γ-position of the...

The present manuscript reviews the findings of different research studies that evaluate use fungal solid-state (SSF) and submerged culture fermentation (SCF) with agro-industrial residues as substrates to enhance production polyphenols their possible uses food additives. Some (peels, pulps seeds) are an important source phenolic acids (p-coumaric, p-hydroxybenzoic, chlorogenic, cinnamic, feruli...

A RP-HPLC method with photodiode array detection (DAD) was developed to separate, identify and quantify simultaneously the most representative phenolic compounds present in Madeira and Canary Islands wines. The optimized chromatographic method was carefully validated in terms of linearity, precision, accuracy and sensitivity. A high repeatability and a good stability of phenolics retention time...

Extracts from leaf sheaths of farmers' varieties of dye sorghum cultivated and used in Benin as a source of biocolorings were analyzed for their anthocyanidin and phenolic contents, as well as their antioxidant capacity. The aim was to identify and quantify the types of anthocyanin and phenolic acids. The total anthocyanin content of the leaf sheaths ranged from 13.7 to 35.5 mg of cyanidin 3-gl...

The contents of free phenolic acids and cinnamic acid were determined using an HPLC method in methanolic extracts from biomass of Schisandra chinensis (Turcz.) Baill. (Chinese magnolia vine) at different stages of organogenesis, cultured in vitro on a few variants of Murashige and Skoog (MS) medium, containing different concentrations of plant growth regulators 6-benzylaminopurine (BAP) and 1-n...

The ability of Clostridium aerotolerans DSM 5434T, Clostridium celerecrescens DSM 5628T, Clostridium methoxybenzovorans DSM 12182T, Clostridium stercorarium ATCC 35414T, Clostridium subterminale DSM 2636, Clostridium termitidis DSM 5398T, Clostridium thermolacticum DSM 2910T, Clostridium thermopalmarium DSM 5974T and Clostridium xylanolyticum DSM 6555T to metabolize cinnamic acid and various de...
