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.
Journal ArticleDOI
Cistaceae aqueous extracts containing ellagitannins show antioxidant and antimicrobial capacity, and cytotoxic activity against human cancer cells.
Enrique Barrajón-Catalán,Salvador Fernández-Arroyo,Domingo Saura,Emilio Guillén,Alberto Fernández-Gutiérrez,Antonio Segura-Carretero,Vicente Micol +6 more
TL;DR: Both extracts showed a notorious capacity to inhibit the proliferation of M220 pancreatic cancer cells and MCF7/HER2 and JIMT-1 breast cancer cells, and their cytotoxic activity against several cancer cells may deserve further attention.
Journal ArticleDOI
Verbascoside, isoverbascoside, and their derivatives recovered from olive mill wastewater as possible food antioxidants.
Angela Cardinali,Sandra Pati,Fiorenza Minervini,Isabella D'Antuono,Vito Linsalata,Veronica M.T. Lattanzio +5 more
TL;DR: Individual verbascoside was more active as a scavenger of reactive oxygen species and as a chemopreventive agent protecting low-density lipoproteins from oxidative damage than the LH-20 fraction.

Quantification of the polyphenolic fraction and in vitro antioxidant and in vivo anti-hyperlipemic activities of Hibiscus sabdariffa aqueous extract
Salvador Fernández-Arroyo,Inmaculada C. Rodríguez-Medina,Raúl Beltrán-Debón,Federica Pasini,Jorge Joven,Vicente Micol,Antonio Segura-Carretero,Alberto Fernández-Gutiérrez +7 more
TL;DR: In this article, the authors quantified the polyphenolic fraction, anthocyanins and other polar compounds, the antioxidant capacity and the anti-hyperlipemic action of the aqueous extract of Hibiscus sabdariffa.
Journal ArticleDOI
Phytosynthesis of silver nanoparticles using aqueous leaf extracts of Lippia citriodora: Antimicrobial, larvicidal and photocatalytic evaluations.
Elias E. Elemike,Elias E. Elemike,Damian C. Onwudiwe,Anthony C. Ekennia,Richard C. Ehiri,Nnaemeka Nnaji +5 more
TL;DR: The nanoparticles showed better antimicrobial activities when compared to the crude plant extract against several screened pathogens and exhibited photocatalytic properties on an industrial waste pollutant, methylene blue.

The ferric reducing ability of plasma (FRAP) as a measure of 'antioxidant power' : the FRAP assay
TL;DR: The FRAP assay offers a putative index of antioxidant, or reducing, potential of biological fluids within the technological reach of every laboratory and researcher interested in oxidative stress and its effects.
Journal ArticleDOI
Superoxide Dismutase AN ENZYMIC FUNCTION FOR ERYTHROCUPREIN (HEMOCUPREIN)
Joe M. McCord,Irwin Fridovich +1 more
TL;DR: The demonstration that O2·- can reduce ferricytochrome c and tetranitromethane, and that superoxide dismutase, by competing for the superoxide radicals, can markedly inhibit these reactions, is demonstrated.
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
Polyphenols: food sources and bioavailability
TL;DR: The nature and contents of the various polyphenols present in food sources and the influence of agricultural practices and industrial processes are reviewed, and bioavailability appears to differ greatly between the variousPolyphenols, and the most abundantpolyphenols in the authors' diet are not necessarily those that have the best bioavailability profile.
Journal ArticleDOI
Antioxidant properties of phenolic compounds
TL;DR: It is now possible to establish the antioxidant activities of plant-derived flavonoids in the aqueous and lipophilic phases, and to assess the extent to which the total antioxidant potentials of wine and tea can be accounted for by the activities of individual polyphenols.
