The Berberis vulgaris (BV) plant has been extensively used as a traditional medicine in some part of Asian region especially in Western Asia. The BV fruits is claimed also to have anti-viral activities, and as a treatment for chronic candidiasis, indigestion and parasites. The present study was conducted to evaluate the antioxidative activity, nutritional and antinutritional composition of Berb...

Olive fruits and oils contain an array of compounds that contribute to their sensory and nutritional properties. Phenolic compounds in virgin oil and olive-derived products have been proven to be highly beneficial for human health, eliciting increasing attention from the food industry and consumers. Although phenolic compounds in olive fruit and oil have been extensively investigated, allowing ...

Studies have demonstrated that phenolic compounds andcarotenoids are essential for prevention of diseases. On the other hand, endogenous ethylene enhances the ripening of fruits and stimulatesthe biosynthesis of carotenoids as well as chlorophylls destruction. The aim of this study was to evaluate the effect of rootstocks on phenolic compounds andcarotenoids. The contents of individual phenolic...

nowadays, the use of natural antioxidants as alternative antioxidants is more acceptable than synthetic antioxidants mainly for negative effects such as carcinogenicity and toxicity. this has led to an increasing interest in the search for natural antioxidants. the objectives of this study were to measure total crude phenolic compounds and in sorghum grain as natural antioxidant sources, to det...

The effect of germination conditions on the nutritional benefits of germinated brown rice flour (GBR) bread has been determined. The proximate composition, phytic acid, in vitro protein digestibility and in vitro enzymatic hydrolysis of starch, glucose and starch content, as well as the most relevant bioactive compounds (GABA, γ-oryzanol and total phenolic compounds) and antioxidant activity of...

In the present study, the proximate composition, sugar, minerals, total phenolic and flavonoid compounds, and amino acids in Calystegia japonica (C. japonica) were measured to determine if it can be used as a nutritional and functional material for the development of valuable foods. The mean crude protein, fat, and ash contents of the leaves were 5.75, 2.46, and 7.77%, respectively. The soluble...

Cider apple cultivars typically contain high concentrations of tannins (phenolic compounds) and/or acids. The phenolic content some cider apples far exceeds that white wine grapes, yet modern global styles are often fermented using yeast strains originally selected and commercialized for production. potential compounds in juice to influence fermentation rate or aromas generated during is not co...

Objectives: Leaves and flowers ofElaeagnus angustifolia contain phenolic and flavonoid compounds. These compounds have antioxidant properties that protect cells from oxidative damage. The aim of this study was to determine and analyze total phenolic and flavonoid content of leaves and flowers in two E. angustifolia variants using different solvents (ethanol and methanol). Materials and Methods:...

The aims of this study were to quantify the phenolic content and evaluate the antioxidant potential of extracts from the bark and leaves of C. pyramidalis and S. glandulosum. The total phenolic content (TPC) and total tannin content (TTC) were determined using the Folin-Ciocalteu method, and the total flavonoids content (TFC) was measured via complexation with aluminum chloride. The antioxidant...
