Extraction, separation, and detection methods for phenolic acids and flavonoids
TL;DR: This review provides an updated and extensive overview of methods and their applications in natural product matrices and samples of biological origin and critically appraises recent developments and trends.

Simultaneous determination of catechins, caffeine and gallic acids in green, Oolong, black and pu-erh teas using HPLC with a photodiode array detector.
Yuegang Zuo,Hao Chen,Yiwei Deng +2 more
TL;DR: Analysis of sample extraction data demonstrated that the single extraction used in the previous studies with aqueous acetonitrile or methanol is not sufficient; the multiple extraction procedure is essential for the quantitative analysis of catechins, phenolic acids and caffeine in teas.

Analysis of flavonoids and phenolic acids in Greek aromatic plants: Investigation of their antioxidant capacity and antimicrobial activity
TL;DR: The phenolic fraction of plant extracts has been linked to their antioxidant capacity and antimicrobial activity as discussed by the authors, and the antioxidant capacity was determined, in dried plants and in their methanol extracts, with the Rancimat test using sunflower oil as substrate.
Journal ArticleDOI
Strategies for the determination of bioactive phenols in plants, fruit and vegetables
TL;DR: Plant phenols are reactive species and their ultimate fate has been relatively neglected, making data handling and informatics important topics that warrant a separate review.

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.

Content of potentially anticarcinogenic flavonoids of 28 vegetables and 9 fruits commonly consumed in the Netherlands
TL;DR: The content of the potentially anticarcinogenic flavonoids quercetin, kaempferol, myricet in, apigenin, and luteolin of 28 vegetables and 9 fruits was determined by RP-HPLC with UVdetection.
Journal ArticleDOI
Reduction of bacteriuria and pyuria after ingestion of cranberry juice.
TL;DR: It is suggested that use of a cranberry beverage reduces the frequency of bacteriuria with pyuria in older women and prevalent beliefs about the effects of cranberry juice on the urinary tract may have microbiologic justification.

Analysis of phenolic acids and flavonoids by high-pressure liquid chromatography☆
Larry W. Wulf,C. W. Nagel +1 more
TL;DR: A high pressure liquid chromatographic (HPLC) technique for the separation and quantification of three classes of naturally occurring phenolic compounds has been developed in this article, which offers selectivity, resolution, speed, and sensitivity (minimum detectable amounts below 50 ng) far superior to classical techniques such as paper chromatography.
