Antioxidant activities of Sechium edule (Jacq.) Swartz extracts
TLDR
The antioxidant properties of Sechium edule extracts were tested by three established in vitro methods, namely reducing power, β-carotene linoleate model and 1,1- diphenyl-2 picrylhydrazyl (DPPH) radical-scavenging.About:

In vitro models for antioxidant activity evaluation and some medicinal plants possessing antioxidant properties: An overview
TL;DR: An attempt has been made to review different in vitro models for estimating antioxidant properties of natural products from medicinal plants, and a large number of plants showing in vitro antioxidant activity are listed but in vivostudies are lacking.

In vitro and in vivo antioxidant activity of aqueous extract from Choerospondias axillaris fruit
Journal ArticleDOI
Polyphenolic content and antioxidant properties of Moringa oleifera leaf extracts and enzymatic activity of liver from goats supplemented with Moringa oleifera leaves/sunflower seed cake.
TL;DR: The present study suggests that M. oleifera could be a potential source of compounds with strong antioxidant potential and the reducing power of both solvent extracts showed strong antioxidant activity in a concentration dependent manner.

Analysis of total phenols and other oxidation substrates and antioxidants by means of folin-ciocalteu reagent
TL;DR: Aggregate analysis of this type is an important supplement to and often more informative than reems of data difficult to summarize from various techniques, such as high-performance liquid chromatography (HPLC) that separate a large number of individual compounds.

Antioxidant activity of various tea extracts in relation to their antimutagenicity
Gow-Chin Yen,Hui-Yin Chen +1 more
TL;DR: The relationship between antioxidant activity and antimutagenicity of various tea extracts (green tea, pouchong tea, oolong tea and black tea) was investigated in this article, which showed that all tea extracts exhibited markedly antioxidant activity.

Flavonoids—Chemistry, metabolism, cardioprotective effects, and dietary sources
N.C. Cook,Samir Samman +1 more
TL;DR: The structural requirements for the antioxidant and free radical scavenging functions of flavonoids include a hydroxyl group in carbon position three, a double bond between carbon positions two and three, carbonyl groups in carbon positions four, and polyhydroxylation of the A and B aromatic rings.
Journal ArticleDOI
Antioxidant activity of dietary polyphenols as determined by a modified ferric reducing/antioxidant power assay
TL;DR: The antioxidant (AO) activity of polyphenols (PPs) was determined for the first time using a modified FRAP (ferric reducing/antioxidant power) assay and polyphenol's AO efficiency seemed to depend on the extent of hydroxylation and conjugation.

Screening of radical scavenging activity of some medicinal and aromatic plant extracts
TL;DR: In this paper, 12 medicinal and aromatic plants were investigated for their radical scavenging activity using DPPH and ABTS assays: Salvia sclarea, Salvia glutinosa, Salmine pratensis, Lavandula angustifolia, Calendula officinalis, Matricaria recutita, Echinacea purpurea, Rhaponticum carthamoides, Juglans regia, Melilotus officinalIS, Geranium macrorrhizum and Potentilla fruticosa.
