Revisiting the oxidation of flavonoids: loss, conservation or enhancement of their antioxidant properties
(MDPI, 2022)
Flavonoids display a broad range of health-promoting bioactivities. Among these, their capacity to act as antioxidants has remained most prominent. The canonical reactive oxygen species (ROS)-scavenging mode of the antioxidant ...
Rat kidney antioxidant response to long-term exposure to flavonol rich red wine
(2002)
This study evaluated the antioxidant defense system of the rat kidney following chronic exposure to red wine rich in flavonols. Both ethanol and antioxidant non-alcoholic wine components, mainly polyphenols, could contribute ...
Total Phenolics Antioxidant Activity And Phytochemical Profile Of Some Plants From The Yotoco National Protected Forest. Valle Del Cauca, Colombia.
(2015-09-21)
Determining the antioxidant activity and the total phenolic content are routine procedures in most
natural product laboratories; however, when dealing with large number of samples, it is necessary
to employ methods that ...
Assessment of antibacterial and antioxidant properties of chitosan edible films incorporated with maqui berry (Aristotelia chilensis)
(Elsevier, 2015)
The purpose of this work was to evaluate chitosan edible films (CH) incorporated with maqui berry extracts (MB) for (i) the inhibition growth of some bacterial strains (ii) their total phenolic (TPC) and total flavonoid ...
Fetal growth restriction is related to placental levels of cadmium, lead and arsenic but not with antioxidant activities
(2009)
The objectives of this study were: to measure some essential metals and toxicants in placentas of mothers delivering neonates with fetal growth restriction, and to establish potential associations between environmental ...
Evaluation of the Antioxidant Activity of the Flavonoids Isolated from Heliotropium Sinuatum Resin Using ORACFL, DPPH and ESR Methodologies
(Sociedad Chilena Química, 2016)
The antioxidant capacity has been determined for a number of flavonoid compounds from Heliotropium sinuatum, a plant that grows in arid areas in the north of Chile. The methodologies used were: ORAC(FL) (oxygen radical ...
Determination of antibacterial, antioxidant, antiplatelet and inhibition of cholinesterase activities from the methanolic extracts of Azorella species (Apiaceae)
(2013)
In this study, we investigated the potential antibacterial, antioxidant and anti-platelet activities and the inhibition of cholinesterase from the methanolic extracts obtained from aerial parts of the two species of Azorella: ...
New insights into the antioxidant activity of hydroxycinnamic and hydroxybenzoic systems: Spectroscopic, electrochemistry, and cellular studies
(Informa Healthcare, 2014)
© 2014 Informa UK, Ltd. A series hydroxycinnamic and gallic acids and their derivatives were studied with the aim of evaluating their in vitro antioxidant properties both in homogeneous and in cellular systems. It was ...
Study of Coumarin-Resveratrol Hybrids as Potent Antioxidant Compounds
(MDPI AG, 2015)
In the present work we synthesized a selected series of hydroxylated
3-phenylcoumarins 5–8, with the aim of evaluating in detail their antioxidant properties.
From an in depth study of the antioxidant capacity data ...
