Standardized methods for the determination of antioxidant capacity and phenolics in foods and dietary supplements.
Methods available for the measurement of antioxidant capacity are reviewed, presenting the general chemistry underlying the assays, the types of molecules detected, and the most important advantagesExpand
Lipophilic and hydrophilic antioxidant capacities of common foods in the United States.
TLDR
The data demonstrated that processing can have significant effects on ORAC(FL). Expand
Concentrations of anthocyanins in common foods in the United States and estimation of normal consumption.
TLDR
On the basis of the concentration data and updated food intake data from NHANES 2001-2002, the daily intake of ACNs is estimated to be 12.5 mg/day/person in the United States, and the different aglycones, cyanidin, delphinid in, and malvidin were estimated to contribute 45, 21, and 15%, respectively, of the total ACN intake. Expand
Assays for hydrophilic and lipophilic antioxidant capacity (oxygen radical absorbance capacity (ORAC(FL))) of plasma and other biological and food samples.
TLDR
These methods provide, for the first time, the ability to obtain a measure of "total antioxidant capacity" in the protein free plasma, using the same peroxyl radical generator for both lipophilic and hydrophilic antioxidants. Expand
Characterization of anthocyanins and proanthocyanidins in some cultivars of Ribes, Aronia, and Sambucus and their antioxidant capacity.
TLDR
Among the berries studied in this paper and in berries in general, chokeberry has the highest total anthocyanin concentrations [1480 mg/100 g of fresh weight (FW], whereas the lowest total anthOCyanin concentration in theberries studied was found in the gooseberry cv. Expand
Screening methods to measure antioxidant activity of sorghum (sorghum bicolor) and sorghum products.
TLDR
The ABTS and DPPH methods were demonstrated to have similar predictive power as ORAC on sorghum antioxidant activity and there is a need to standardize these methods to allow for data comparisons across laboratories. Expand

TLDR
This paper presents complete anthocyanin HPLC profiles and MS spectral data of common fruits using the same uniform experimental conditions and identified a number of minor Anthocyanins for the first time. Expand

TLDR
This paper presents complete HPLC profiles and MS spectrometric data, obtained under the same experimental conditions, for common vegetables, pistachio nuts, and sorghum that contain anthocyanins. Expand
Anthocyanins: Structural characteristics that result in unique metabolic patterns and biological activities
TLDR
It is shown that anthocyanins may play an important role in health promotion in terms of obesity prevention, cardiovascular health, anti-inflammatory and anti-cancer effects. Expand
Absorption and metabolism of anthocyanins in elderly women after consumption of elderberry or blueberry.
TLDR
This study demonstrates for the first time that in vivo methylation of cyanidin to peonidin and glucuronide conjugate formation occurs after people consume ACN and demonstrates the low absorption and excretion of ACN compared with other flavonoids. Expand
