Natural Antioxidants in Foods and Medicinal Plants: Extraction, Assessment and Resources.
Xu DP, et al. Int J Mol Sci 2017 - Review. PMID 28067795 Free PMC article.
Natural antioxidants are widely distributed in food and medicinal plants. These natural antioxidants, especially polyphenols and carotenoids, exhibit a wide range of biological effects, including anti-inflammatory, anti-aging, anti-atherosclerosis and anticancer. The effective extraction and proper assessment of antioxidants from food and medicinal plants are crucial to explore the potential antioxidant sources and promote the application in functional foods, pharmaceuticals and food additives. ...

Paper-based DPPH Assay for Antioxidant Activity Analysis.
Sirivibulkovit K, et al. Anal Sci 2018. PMID 29998961 Free article.
The analysis was carried out in one-step by dropping an antioxidant/sample onto the test zone. After reduction by the antioxidant, the DPPH radicals become stable DPPH molecules, resulting in a change in color from deep violet to pale yellow. ...The device was then validated against the traditional spectrophotometric DPPH assay by analyzing the antioxidant activity of 7 tea samples. ...

Antioxidant assays for plant and food components.
Moon JK and Shibamoto T. J Agric Food Chem 2009 - Review. PMID 19182948
Recently, research on natural antioxidants has become increasingly active in various fields. Accordingly, numerous articles on natural antioxidants, including polyphenols, flavonoids, vitamins, and volatile chemicals, have been published. Assays developed to evaluate the antioxidant activity of plants and food constituents vary. Therefore, to investigate the antioxidant activity of chemical(s), choosing an adequate assay based on the chemical(s) of interest is critical. ...

Methods to Assess the Antioxidative Properties of Probiotics
Zolotukhin PV, et al. Probiotics Antimicrob Proteins 2018 - Review. PMID 29249065
Notably, these capabilities of probiotics appear to be associated with their antioxidant properties. The mechanisms of antioxidant action of probiotics range from immediate biochemical scavenging of reactive substances to induction of signaling events leading to increased capacity of the host's cytoprotective systems. ...This review revises the versatile toolbox, which can be used to assess the antioxidant properties of probiotics....

Activity-Guided Identification of in Vitro Antioxidants in Beer.
Spreng S and Hofmann T. J Agric Food Chem 2018. PMID 29287473
In order to locate the key antioxidants contributing to oxidative stability of beer, activity-guided fractionation in combination with the oxygen radical absorbance capacity (ORAC) assay, hydrogen peroxide scavenging (HPS) assay, and linoleic acid (LA) assay was applied to a pilsner-type beer. ...On a molar comparison, the hordatines A-C, saponarin, and quercetin-3-O-β-d-(6″-malonyl)glucoside were evaluated with the highest antioxidant activities of all identified beer constituents, reaching values of 10-17.5 (ORAC), 2.0-4.1 (HPS), and 1.1-6.1 μmol TE/μmol (LA) for hordatines A-C....

Analysis of two methods to evaluate antioxidants.
Tomasina F, et al. Biochem Mol Biol Educ 2012. PMID 22807430 Free article.
Antioxidants play an important metabolic role, preventing oxidative stress-mediated cell and tissue injury. Knowing the antioxidant content of nutritional components can help make informed decisions about diet design, and increase the commercial value of antioxidant-rich natural products. ...We have chosen two widely used and inexpensive methods, Trolox-equivalent antioxidant capacity and the ferric reducing antioxidant power assays, to evaluate the antioxidant content of several fruits, and to compare and analyze the correlation between both assays....

Analysis of natural antioxidants by capillary electromigration methods.
Herrero M, et al. J Sep Sci 2005 - Review. PMID 16013814
In this work, an exhaustive survey of capillary electromigration methods used to analyze natural antioxidants is presented together with some discussion of the use of these substances use as functional foods. ...The compounds concerned are catechins, isoflavones, anthocyanins, phenolic acids, vitamins, as well as other less common natural substances that have shown antioxidant activity....
