Bound phenolics in foods, a review

Food Chemistry, 2014
Among phytochemicals, phenolic compounds have been extensively researched due to their diverse health benefits. Phenolic compounds occur mostly as soluble conjugates and insoluble forms, covalently bound to sugar moieties or cell wall structural components.

Phenolic profiles and antioxidant activities of free, esterified and bound phenolic compounds in walnut kernel

Food Chemistry, 2021
The free, esterified and bound forms of 37 phenolic compounds (including hydroxybenzoic acid, hydroxycinnamic acids, flavanols, flavonols and flavones) from walnut kernel (Juglans regia L.) were investigated in this study. Results showed that the majority of walnut phenolics were presented in the free form (51.1%-68.1%), followed by bound (21.0%-38.0%)

Infrared spectra of the phenol–Ar and phenol–N2 cations: proton-bound versus π-bound structures

Chemical Physics Letters, 2000
Abstract Infrared spectra of the phenol–Ar/N 2 cations (Ph + –Ar/N 2 ), produced in an electron impact ion source, are analyzed in the vicinity of the O–H stretch fundamental, ν 1 . For Ph + –Ar two isomers are identified by their ν 1 frequency shifts upon complexation: the proton-bound global minimum (Δ ν 1 =−65 cm −1 ) and the π -bound ...

Antioxidative Activity of Bound-Form Phenolics in Potato Peel

Bioscience, Biotechnology, and Biochemistry, 2006
Free and bound-form phenolics were isolated from potato (cv. Toyoshiro) flesh and peel. The free and bound-form phenolics in the peel showed high DPPH radical scavenging activity, while those in the flesh showed low activity. The total amount of chlorogenic acid and caffeic acid in the free-form phenolics from the peel was highly correlated with the ...
