We selected three scab-resistant and powdery mildew-tolerant varicoloured cultivars for testing, and found they had qualitatively similar spectra of phenolic acids. The major free phenolic acid in both peel and flesh of the apples was chlorogenic acid, followed by (at much lower concentrations) ...
The major constituents of free phenolic acids in the ginseng leaves were syringic (139.4 mg/l00 g) and sinapic (131.2 mg/100 g) acids. On the other hand, hydrolyzed phenolic acids in the ginseng leaves were mainly composed of caffeic (59.4 mg/100 g), ferulic (49.5 mg/100 g), and p...
The intestinal absorption characteristics of phenolic acids (PAs) have been elucidated in terms of their affinity for the monocarboxylic acid transporter (MCT). Recently, the involvement of the stomach has been implicated in the absorption of polyphenols. The present work demonstrates that the gastric...
1 Biosynthesis of phenolic acids and their derivatives. Structures of pCA- (green), CaA- (orange) and FA-derived (pink) natural products, and their pharmaceutical properties. Extended Data Fig. 2 Engineering strategies for improving the production of CaA and FA. The engineered gene targets for ...
Phenolic acids and tanshinones are two major bioactive components in Salvia miltiorrhiza Bunge. A novel endogenous R2R3-MYB transcription factor, SmMYB36, was identified in this research. This transcript factor can simultaneously influence the content of
secondary metabolites. The inhibitory effect of phenolic acids was significantly influenced by exposure dose and phenolic acid species. Caffeic acid has the most efficient algal inhibition ability (96 h-EC50of 5.8 mg/L). In contrast, the other 5 analogs (cinnamic acid,p-coumaric acid, 3-hydroxyc...
Populations of bacteria, fungi and actinomycetes in Portsmouth A 1- and B,-soil material were affected in different ways by repeated enrichment with ferulic, p-coumaric, p-hydroxybenzoic or vanillic acids. Responses varied with type of soil material and phenolic acid, phenolic acid concentration, ...
Allelochemical substitutions salicylic acid,p-hydroxybenzonic acid,cinnamic acid,vanillic acid and ferulic acid were tested in a gyrating regression experiment to study the weed-suppressive effect of phenolic acids on the root growth of barnyardgrass.The results showed that cinnamic acid had a signific...
The antioxidant activities of 18 typical phenolic acids were investigated using 2, 2′-diphenyl-1-picrylhydrazyl (DPPH) and ferric ion reducing antioxidant power (FRAP) assays. Five thermodynamic parameters involving hydrogen atom transfer (HAT), single-electron transfer followed by proton transfer (SET...
