The present investigation highlights the free radical scavenging activity of Melochia corchorifolia, Sida acuta and Saccharum officinarum leaf extracts and their Phenolic contents by determining DPPH, Nitric oxide, Hydroxyl and Hydrogen peroxide scavenging activity. The shade dried leaves were coarsely powdered and subjected to fractional extraction by using chloroform and ethanol. The extracts...

The purpose of this study was to evaluate the antioxidant and antimicrobial properties of extracts of different fractions of two tomato plant cultivars. The stems, roots, leaves, and whole-plant fractions were evaluated. Tomatine and tomatidine were identified by HPLC-DAD. The leaf extracts from the two varieties showed the highest flavonoids, chlorophyll, carotenoids, and total phenolics conte...

Thirty-seven China wines, produced from different geographical origins, were examined in this study. The antioxidant activity of wines was measured by different analytical methods: oxygen radical absorbance capacity (ORAC), reducing power, 2,2-azino-di-(3-ethylbenzothialozine-sulphonic acid) (ABTS), 2,2diphenyl-1-picrylhydrazyl (DPPH ), hydroxyl radical-scavenger activity, superoxide radical-sc...

Potatoes contain antioxidants such as flavonoids, carotenoids and ascorbic acid. High level consumption worldwide makes potato a valuable source of phytonutrients. Developing new varieties with high nutritional value in combination resistance to pathogens is an important task. In this study, 25 interspecific hybrids Synchytrium endobioticum, common scab, silver rhizoctonia, nematodes PVY were e...

A laboratory equipment for combinations of convective and microwave drying is presented. It was applied parsnips. Lower energy consumption at heating the product intermitted confirmed in comparison to continuous with hot air. In addition, influence process on phenols flavonoids contents were investigated. The results give useful information organisation operating modes vegetables.

Faba bean (Vicia faba L.) as the most cultivated leguminous species in the world, is an excellent source of protein, dietary fiber, micronutrients and phytochemicals. A field experiment was conducted at Ghazala, Zagazig University, Sharkia Governorate during 2015, to study the effect of plant Growth Regulator such as; Gibberellic acid (GA3) and Inidol acetic acid (IAA) on antioxidant contents o...

This study assessed the primary impacts of exogenous melatonin (MT) treatment on grape berry metabolism. Exogenous MT treatment increased the endogenous MT content and modified berry ripening. Transcriptomic analysis revealed that the processes of polyphenol metabolism, carbohydrate metabolism and ethylene biosynthesis and signaling were the three most significantly altered biological processes...
