“…For example, green tea as one ingredient of the eQ-line contains antioxidants in high amounts (Cabrera et al, 2006;Speisky et al, 2006;Tipoe et al, 2007). Antioxidant activities were also reported for fruits and berries present in the drinks (for example, see Wilska-Jeszka, 1996;Anag-nostopoulou et al, 2004;Beattie et al, 2005;Hanamura et al, 2005;Netzel et al, 2005;Dai et al, 2007;Jayaprakashaa et al, 2007). However, Let's get red [intense] might have the highest total amount of antioxidants.…”

The present study was undertaken to investigate the antioxidative effects of three different functional drink concepts especially designed to improve the body's performance and function and to possess high antioxidant activities. The concepts based on the mixture of various plant ingredients were: (1) eQ - equalize your nutrient balance, brain line [acerola-dragon fruit], (2) eQ - equalize your nutrient balance, beauty line [honey-pepper] and (3) Let's get red [intense]. By using a cell-based test assay, the study investigated the potential of the functional drinks to inactivate reactive superoxide anion radicals generated by inflammation-mediating cells as well as the effect on basal metabolism of these cells (antioxidant and antiinflammatory potential). In addition, by using a cell-free test assay the potential of the drinks to inactivate free exogenous superoxide anion radicals (scavenger effect) was investigated. The data presented here demonstrate the different radical scavenging, antioxidant and anti-inflammatory potential of the functional drink concepts. In particular Let's get red [intense] turned out to be the most potent drink in this respect and demonstrated marked efficacy in scavenging, antioxidant and antiinflammatory action.

“…Juices are suitable food products in terms of ingestion of health protective phytochemicals. Bioactive components may even be better absorbed from juices than from plant tissues, as it was demonstrated for ascorbic acid (Netzel et al, 2005;. Epidemiological studies and associated meta-analyses strongly suggest that long term consumption of diets rich in plant polyphenols offer protection against development of cancers, cardiovascular diseases, diabetes, osteoporosis and neurodegenerative diseases (Pandey and Rizvi, 2009).…”

Extract of grape Vitis vinifera has been reported to exhibit antioxidant and antimutagenic activities and the phenolic compounds play a vital role in determining these activities. Therefore; the objective of the present study was to evaluate the antioxidant and anti-mutagenic activities as well as the phenolic composition of different grape cultivar extracts collected from Taif region. The grape cultivars namely; Italian, American, Lebanese, Taify b and Taify e were collected at maturity stage to represent Taif region cultivars. The total concentrations of phenoles were determined for the five cultivar extracts and results indicated that the concentrations ranged from 115-960 mg L −1 Gallic Acid Equivalent (GAE). Also, HPLC analysis included was carried out of nine important phenolic compounds namely; Cyanidine chloride, Myricetin, Chrysin, Quercetin, Delphinidine chloride, Malvidine chloride, Naringenin, Galangin and Caffeic acid. Significant differences among cultivars were obtained for each compound. However, the highest cultivar for each compound differed from compound to another. At the same time, DPPH was used to estimate antioxidant activity and the data showed that different grape cultivar extracts were able to quench 47-60% of DPPH radical solution and to exhibited potent radical scavenging activity. Also, antimutagenic activity was measured as a decrease of chromosomal aberrations in bone marrow cells of mice treated with the mutagen Endoxan. Results showed that treatment of mice with grape cultivar extracts resulted in a significant decrease in all types of chromosomal aberrations induced by Endoxan. Also, the anticlastogenic effect was measured using micronulei test and results indicated that all grape cultivar extracts reduced significantly the effect of Endoxan on micronulei test. Finally, treatment of mice with grape cultivar extracts enhanced mitotic index of mice bone marrow cells reduced by Endoxan treatment. The relationship between phenolic compound concentrations and antioxidant capacity was discussed.
