Olive mill wastes: Biochemical characterizations and valorization strategies
TL;DR: In this article, the authors highlight on the treatment approaches and valorization options for dealing with olive mill waste residues, predominantly those allowing for the recovery of valuable natural components such as phenolic compounds, dietary fibers, animal feed, biofuel, biogaz, enzymes, polymers and other.

Verbascoside — A review of its occurrence, (bio)synthesis and pharmacological significance
TL;DR: Verbascoside is a phenylethanoid glycoside that was first isolated from mullein but is also found in several other plant species as mentioned in this paper, including genetically transformed roots.

Recovery and concentration of polyphenols from olive mill wastewaters by integrated membrane system
Esperanza M. Garcia-Castello,Alfredo Cassano,Alessandra Criscuoli,Carmela Conidi,Enrico Drioli +4 more
TL;DR: This work analysed the potentialities of an integrated membrane system for the recovery, purification and concentration of polyphenols from olive mill wastewater (OMW) and the performance of both processes was compared in terms of evaporation fluxes.

Removal of organic load and phenolic compounds from olive mill wastewater by Fenton oxidation with zero-valent iron.
TL;DR: In this article, a pre-treatment of olive mill wastewater by Fenton Oxidation with zero-valent iron and hydrogen peroxide was investigated to improve phenolic compounds degradation and the chemical oxygen demand (COD) removal.

Antioxidant activity applying an improved ABTS radical cation decolorization assay.
Roberta Re,Nicoletta Pellegrini,Anna R. Proteggente,Ananth S. Pannala,Min Yang,Catherine Rice-Evans +5 more
TL;DR: A method for the screening of antioxidant activity is reported as a decolorization assay applicable to both lipophilic and hydrophilic antioxidants, including flavonoids, hydroxycinnamates, carotenoids, and plasma antioxidants.
Journal ArticleDOI
Structure-antioxidant activity relationships of flavonoids and phenolic acids
TL;DR: The factors underlying the influence of the different classes of polyphenols in enhancing their resistance to oxidation are discussed and support the contention that the partition coefficients of the flavonoids as well as their rates of reaction with the relevant radicals define the antioxidant activities in the lipophilic phase.
Journal ArticleDOI
The Chemistry behind Antioxidant Capacity Assays
TL;DR: This analysis suggests that the total phenols assay by FCR be used to quantify an antioxidant's reducing capacity and the ORAC assay to quantify peroxyl radical scavenging capacity, to comprehensively study different aspects of antioxidants.
Journal ArticleDOI
Flavonoids as Antioxidants
TL;DR: This review presents the current knowledge on structural aspects and in vitro antioxidant capacity of most common flavonoids as well as in vivo antioxidant activity and effects on endogenous antioxidants.

A Novel Method for Measuring Antioxidant Capacity and its Application to Monitoring the Antioxidant Status in Premature Neonates
Nicholas J. Miller,Catherine Rice-Evans,Michael J. Davies,Vimala Gopinathan,Anthony D Milner +4 more
TL;DR: The method has been applied to investigate the total plasma antioxidant capacity of neonates and how this may be compromised in prematurity, and an antioxidant ranking was established based on their reactivity relative to a 1.0 mmol/l Trolox standard.
