SCOPE Berries are an excellent source of dietary flavonoids which have several health benefits. METHODS AND RESULTS We evaluated well-characterized anthocyanins (ANCs) and proanthocyanidins (PACs) from fermented blueberry-blackberry beverages. Wines were produced from highbush blueberries and blackberries grown in Illinois and blended to create ratios ranging from 100% blueberry to 100% black...

The aim of the present study was to evaluate the protective effects of blueberry extract on oxidative stress and inflammatory parameters in a model of mania induced by ketamine administration in rats. Male rats were pretreated with blueberry extract (200mg/kg, once a day for 14days), lithium chloride (45mg/kg, mood stabilizer used as a positive control, twice a day for 14days), or vehicle. Betw...

SCOPE The aim of this work is to identify which proapoptotic pathway is induced in human colon cancer cell lines, in contact with proanthocyanidins extracted from various berries. METHODS AND RESULTS Proanthocyanidins (Pcys) extracted from 11 berry species are monitored for proapoptotic activities on two related human colon cancer cell lines: SW480-TRAIL-sensitive and SW620-TRAIL-resistant. A...

This study examined the antimicrobial effect of blueberry (Vaccinium corymbosum L.) extracts obtained from four cultivars (Elliott, Darrow, Bluecrop, and Duke) on the growth of Listeria monocytogenes and Salmonella Enteritidis. The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of the extracts against L. monocytogenes and S. Enteritidis in tryptic soy broth ...

Antioxidants from a blueberry beverage may impact plasma vitamins. We examined vitamins/food selection in 12 college athletes during 30 days compared with placebo. Blood was collected before and after exercise at the beginning of the study (day 1) and then after a 30-day period of taking a daily supplemental beverage (day 30). The six trials involved blood that was drawn pre-beverage ingestion/...

Among Vaccinium species, blueberries (Vaccinium myrtillus L.) and lingonberries (Vaccinium vitis-idaea) are popular in the human diet. In this study, total phenolic, total flavonoid and total monomeric anthocyanin contents in the ethanol-water extracts of blueberry and lingonberry fruits grown wild in the forests in the central region of Poland were assayed. Antioxidant activities of the extrac...

Highbush blueberry (Vaccinium corymbosum L.) is a native North American crop dependent upon pollen movement by bees for high fruit set and large berries. Commercial blueberry farmsuse honeybees (ApismelliferaL.) to provide pollination services, but there is concern regarding their long-term sustainability as crop pollinators. We conducted a 3-yr study at 15 farms to identify the bee community a...

In this study, as an approach to possible pharmacokinetic interactions between antidiabetic agents and health foods, we investigated the binding of metformin and glibenclamide to aojiru, kurosu, and blueberry extract using a dialysis method. The permeation of metformin from the inner to the outer side of the dialysis tube during 90 min was not altered in the presence of aojiru or kurosu, and sl...

Carvalho M., Matos M., Carnide V., 2014. Fingerprinting of Vaccinium corymbosum cultivars using DNA of fruits. Hort. Sci. (Prague), 41: 175–184. In recent years the production and consumption Vaccinium corymbosum has increased. Highbush blueberry cultivars are divided into three types, northern, intermediate and southern. The traditional methods for classification of highbush blueberry cultivar...

In this study, blueberry essential oil as a core material was microencapsulated with Inulin and β-cyclodextrin at a ratio of 1:5 (core: wall). Oil in water nano-emulsions were prepared by ultrasonic liquid processors and then transformed to encapsulate powder in spray dryer. Dried powder was stored at 4 ˚C in refrigerator for determining moisture, encapsulation efficiency and morphology prop...
