چکیده
The aim of this study was to investigate and compare Vaccinium myrtillus L. extracts obtained in ultrasonic condition with different water/methanol and water/ethanol extraction mixture acidified with 0.1% HCl. The extracts were analyzed for monomeric anthocyanins contents, total phenolics content and antioxidant activities. The highest anthocyanins content (3888 mg/L), total phenolics content (6325 mg GAE/L) and the best antioxidant activity were obtained for the bilberries extract with 100% methanol. Also, there is a good correlations between antioxidant activitiy and total phenolics content (R = 0.9763) for water/methanol series extracts.
