The total phenolic content and antioxidant capacity of three apple ciders produced in Poland were examined. The total phenolic content was determined by the Folin-Ciocalteau method and results were expressed in gallic acid equivalents with range from 0.21±0.003 to 0.30±0.004 mg/ml and Trolox equivalents ranging 0.88±0.012 to 1.24±0.015 mg/ml. The antioxidant activity was estimated by two method...

Wounding of fresh produce may elicit an increase in antioxidant capacity associated with wound-induced phenolic compounds. However, there have been no reports on the wounding response of different types of fresh produce. Changes in antioxidant capacity, total soluble phenolics, ascorbic acid, total carotenoids and total anthocyanins were evaluated after wounding in zucchini, white and red cabba...

BACKGROUND Scrophularia striata (Scrophulariaceae family) is an herbaceous plant that is traditionally used for treatment of microbial infections. OBJECTIVES Antimicrobial and antioxidant activity of different extracts (methanolic, ethanolic, aqueous and ethyl acetate) from S. striata aerial parts was evaluated. MATERIALS AND METHODS The antimicrobial activity of different extracts from S. ...

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...

strawberry (fragaria ananassa duch.) is a good source of natural antioxidants. fruits from eight strawberry (fragaria ananassa duch.) cultivars (‘kurdistan’, ‘merck’, ‘camarosa’, ‘paros’, ‘queen elisa’, ‘ventana’, ‘selva’ and ‘pajaro’) were harvested at ripen stage and analyzed for total phenolic content, total anthocyanin content, vitamin c, total soluble solid and total antioxidant activity. ...

This study aimed to compare the antioxidant content and antioxidant capacity of pulp and peel of two varieties of pomelo fruit (Tambun White and Tambun Pink). Antioxidants including total phenolic content, total flavonoid content and ascorbic acid content were determined using Folin-Ciocalteu reagent assay, aluminium chloride colorimetric assay and AOAC method, respectively. Antioxidant capacit...

in this work, the effect of three-day germination on proximate composition, total phenolic compounds, fatty acid profile, vitamin c content, radical scavenging activity, malondialdehyde content and reducing power of safflower seed was investigated. apart from ash, other parameters including oil, protein and crude fiber contents decreased significantly during germination. phenolics content incre...

The increasing consumers demands to acquire healthier fruits and vegetables as well as the urgency in looking to natural compounds with antioxidant activity and enhanced antimicrobial activity against antibiotic-resistant pathogenic bacterial strains have encouraged a quick expansion of research studies about enhanced phenolic extraction and identification methods. Considering the importance of...

Tibetan tea (Kangzhuan) is an essential beverage of the Tibetan people. In this study, a lyophilized aqueous extract of Tibetan tea (LATT) was prepared and analyzed by HPLC. The results suggested that there were at least five phenolic components, including gallic acid, and four catechins (i.e., (+)-catechin, (-)-catechin gallate (CG), (-)-epicatechin gallate (ECG), and (-)-epigallocatechin gall...

Phenolic profiles and antioxidant properties of purple wheat varieties were investigated to document the effects of bread-making. Bread crust and crumb along with samples collected after mixing, 30 min fermenting, 65 min fermenting, and baking were examined. Free phenolic content (105.4 to 113.2 mg FAE/100 g) significantly (p < 0.05) increased during mixing, fermenting, and baking (65% to 68%)....
