Introduction Structure of plant phenolics or more hydroxy substituents Role of phenolics in olives Properties and function Phenolics as antioxidants Phenolics and fruit quality Factors affecting the phenolic profile of olives Varietal influences Other factors Olive development and maturation Processing and storage Oil production Table olives Analysis Sample preparation Quantification Chromatogr...

The content of total phenolics in roots, leaflets and seeds of a number of Astingulus species from Iran was examined. Phenolics content of the aqueous and methanolic extracts of the species were determined spectrophotometrically. Phenolics content depend on factors such as the species, geographical location of the plants and the organs. Moreover, the content of phenolics depends on the extracti...

Phenolics are the most abundant plant metabolites and are believed to decompose slowly in soils compared to other soil organic matter (SOM). Thus, they have often been considered as a slow carbon (C) pool in soil dynamics models. Here, however, we review changes in our concept about the turnover rate of phenolics and quantification of different types of phenolics in soils. Also, we synthesize c...

In recent years, few classes of natural products have received as much attention as phenolics and polyphenols. This special issue of Molecules, “Phenolics and Polyphenolics”, is a remarkable confirmation of this trend. Several aspects related to phenolics chemistry, comprising the several classes, will be discussed. In addition, the increasing interest in phenolics’ biological activities is cov...

We have previously demonstrated promising anticancer efficacy of orally-fed whole ginger extract (GE) in preclinical prostate models emphasizing the importance of preservation of the natural "milieu". Essentially, GE primarily includes active ginger phenolics viz., 6-gingerol (6G), 8-gingerol (8G), 10-gingerol (10G), and 6-shogaol (6S). However, the druglikeness properties of active GE phenolic...

Sucrose (0.04 to 0.12 m) induces accumulation of both total phenolics and anthocyanin in leaf discs of grapevine (Vitis vinifera L.) incubated in intermittent light. Abscisic acid (20 muM) and 2-chloroethyl phosphonic acid (60 mum) act synergistically with the sucrose to enhance its induction of both total phenolics and anthocyanin. The magnitude of this interaction depends on leaf age. Nitrate...

Phenolics were extracted from litchi fruit pericarp (LFP) tissues, purified and their antioxidant properties analyzed. LFP phenolics strongly inhibited linoleic acid oxidation and exhibited a dose-dependent free-radical scavenging activity against alpha,alpha-diphenyl-beta-picrylhydrazyl (DPPH*) and hydroxyl radicals and superoxide anions. The degradation of deoxyribose by hydroxyl radicals was...

the methanolic extracts, infusions, decoctions and hydrosols of six plants were investigated for their total phenolic contents, antioxidant and antimicrobial activities: mentha piperita (peppermint), thymus vulgaris   (thyme), melissa officinalis (lemon balm), ocimum basilicum (basil), rosmarinus officinalis (rosemary) and     salvia officinalis     (sage) (lamiaceae). total phenolic contents w...

objective: ipomoea mauritiana is used in both ayurveda and folk medicine systems. the tuberous roots are known to be diuretic, depurative, carminative, and anthelmintic. the objective of the current study was to identify phenolic antioxidants from i. mauritiana using spectrophotometric and lc-ms analysis. materials and methods: an activity-guided fractionation and purification process was used t...
