Comparison of Antioxidant Properties of Wild Blueberries (Vaccinium arctostaphylos L. and Vaccinium myrtillus L.) with Cultivated Blueberry Varieties (Vaccinium corymbosum L.) in Artvin Region of Turkey

Abstract

Vaccinium arctostaphylos L. and Vaccinium myrtillus L. which are found naturally in most part of Blacksea Region, and Artvin are generally called bear grape, Trabzon tea, and likapa. In addition, different varieties of blueberry (Vaccinium corymbosum L.) have been cultivated in Artvin region for 5 or 6 years. Blueberries contain appreciable levels of phenolic compounds, including anthocyanins and flavonols that have high biological activity. V. arctostaphylos and V. myrtillus show that natural distrubition with received V. corymbosum of different cultured species in Artvin region will be determined antioxidant activity in this study. In this study showed that wild species had a higher antioxidant effect than cultivated species. V. myrtillus had high total polyphenols (11.539-20.742 mg GAE/g dry sample), flavonoids (1.182-2.676 mg QE/g dry sample) and anthocyanins (3.305-11.473 mg Cyn/g dry sample) than V. corymbosum species. In addition, wild species had high CUPRAC, FRAP and DPPH values. The antioxidant activities found with CUPRAC, expressed as trolox equivalent antioxidant capacity ranged from 0.143 to 0.297 mmol TEAC/g dry sample. Those determined with DPPH expressed as IC50 ranged from 0.229 to 1.178 mg/ml. Those determined with FRAP expressed as

Investigation of antioxidant, α-glucosidase inhibitory, anti-inflammatory and DNA protective properties of Vaccinium arctostaphylos L.

“…In this study, EE had the highest total anthocyanin content with 8.46 ± 0.49 mg CGE/g dry weight among extracts tested. Similar to our findings, Saral reported that ME of V. arctostaphylos was 6.14 ± 0.01 mg CGE/g dry weight (36). The results obtained in this study demonstrated that V. arctostaphylos is rich source of secondary metabolites.…”

“…arctostaphylos fruits from different regions were found to range from 20.74 ± 0.24 mg GAE/ g weight of samples (36). Hasanloo reported that acidic ME of the plants was found to contain 9.48 mg GAE/g dry weight.…”

Application of Rosemary (rosmarinus officinalis l.) Based Natural Antioxidant During Deep Fat Frying of Noodle

“…Also, they are very effective during the storage and transport of oils and fats, but they are less effective at frying temperatures, due to their volatility. However, in the recent years, much of the interest has developed in naturally occurring antioxidants, because of the adverse attention received by the synthetic antioxidants, and because of the worldwide trend to avoid or minimize the use of artificial food additives (Filiz and Seydim, 2014;Gad and Sayd, 2015;Saral et al, 2014). Also the use of natural antioxidants for frying purposes has increased during the last few years (Bera et al, 2006;Budak et al, 2015;Riveros et al, 2015;Urbancic et al, 2014).…”

Chemical variability of wild bilberry (Vaccinium myrtillus L.) populations in northern part of Albania

“…The anthocyanins are found mainly in skin and pulp of the bilberry fruit (Akerstrom, 2010;Oancea et al, 2013;Saral et al, 2015).…”

“…The bilberry contains anthocyanin which is considered to be an important natural antioxidant (Prior et al, 1998;Huang et al, 2012;Saral et al, 2015;Zoratti et al, 2016). Anthocyanins are the colorant/pigment of the fruit and flowers (Chandra et al, 2001;Fe et al, 2010;Huang et al, 2014).…”
