TLDR
The effect of dietary phenolics is currently of great interest due to their antioxidative and possible antic-arcinogenic activities as discussed by the authors, and phenolic acids and flavonoids also function as reducing agents, free radical scavengers, and quenchers of singlet oxygen formation.Abstract:
Flavonoids and phenolic acids make up one of the most pervasive groups of plant phenolics. Due to their importance in plants and human health, it would be useful to have a better understanding of flavonoid concentration and biological activities that could indicate their potentials as therapeutic agents, and also for predicting and controlling the quality of medicinal herbs. Plants and herbs consumed by humans may contain thousands of different phenolic acid and flavonoid components. The effect of dietary phenolics is currently of great interest due to their antioxidative and possible anticarcinogenic activities. Phenolic acids and flavonoids also function as reducing agents, free radical scavengers, and quenchers of singlet oxygen formation. In addition, flavonoids and phenolic acids components play important roles in the control of cancer and other human diseases.
Key words: Flavonoids, phenolic acids, biological activities, antioxidative, anticarcinogenic.read more

The Potential of Plant Phenolics in Prevention and Therapy of Skin Disorders
Magdalena Działo,Justyna Mierziak,Urszula Korzun,Marta Preisner,Jan Szopa,Jan Szopa,Anna Kulma +6 more
TL;DR: This paper reviews the latest reports on the potential therapy of skin disorders through treatment with phenolic compounds, considering mostly a single specific compound or a combination of compounds in a plant extract.

Chlorogenic acid-mediated gel formation of oxidatively stressed myofibrillar protein.
Yungang Cao,Youling L. Xiong +1 more
TL;DR: The results showed that CA generally inhibited protein carbonyl formation but did not prevent sulphydryl and amine losses caused by oxidation, which can explain why processed meats with phenolic-rich spices and herbs often exhibit variable texture-forming properties.

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.

Polyphenols: food sources and bioavailability
TL;DR: The nature and contents of the various polyphenols present in food sources and the influence of agricultural practices and industrial processes are reviewed, and bioavailability appears to differ greatly between the variousPolyphenols, and the most abundantpolyphenols in the authors' diet are not necessarily those that have the best bioavailability profile.

Jin Dai,Russell J. Mumper +1 more
TL;DR: The anticancer effects of phenolics in-vitro and in- vivo animal models are viewed, including recent human intervention studies, and possible mechanisms of action involving antioxidant and pro-oxidant activity as well as interference with cellular functions are discussed.

Transcriptome Changes for Arabidopsis in Response to Salt, Osmotic, and Cold Stress
TL;DR: Together results from all three stresses identified 2,409 genes with a greater than 2-fold change over control, suggesting that about 30% of the transcriptome is sensitive to regulation by common stress conditions, and supporting the hypothesis that an important function of the circadian clock is to “anticipate” predictable stresses such as cold nights.

Antioxidant capacity of phenolic phytochemicals from various cultivars of plums
TL;DR: In this article, the authors performed polyphenolic phytochemical extractions of six plums (Beltsville Elite B70197, Cacak Best, French Damson, Long John, Stanley, and Gala apples) using 80% aqueous methanol with ultrasound assistance and extracts were analyzed for total phenolics, flavonoids and antioxidant capacity.
