Densitometry was used for quantitative determination of arbutin (Vaccinium vitis idaeae) in leaves of cowberry collected from region of Suwalszczyzna, Poland. Arbutin was extracted using methanol. Chromatography was performed on glass TLC plates with layers of silica gel. The quantitative densitometric analysis was performed using internal standard solution method. On the base of densitometric ...

The effects of blueberry leaf (BBL) on lipid metabolism were studied in obese rats. Feeding of BBL lowered levels of serum lipids and C-reactive protein and alleviated hepatic triglyceride accumulation in the rats. The hypolipidemic effect might be attributable to a reduction of lipogenesis and enhancement of lipolysis in the liver. These results suggest the use of blueberry leaf as a dietary h...

The Andean Region of Colombia has a large variety species with diverse ethnobotanical uses, including industrial, medicinal and food uses. Among these plants are several wild from the genus Vaccinium, which native to mountainous regions country. This review deals potential uses for agraz (V. meridionale) agracejo floribundum) in Colombia, focusing on nutritional their importance security terms ...

Habitat fragmentation can have severe effects on plant pollinator interactions, for example changing the foraging behaviour of pollinators. To date, the impact of plant population size on pollen collection by pollinators has not yet been investigated. From 2008 to 2010, we monitored nine bumble bee species (Bombus campestris, Bombus hortorum s.l., Bombus hypnorum, Bombus lapidarius, Bombus pasc...

Published on behalf license (http://creativecommons.org/licenses/by/4.0/) Hunting by humans can be a potent driver of selection for morphological and life history traits in wildlife populations across continents and taxa. Few studies, however, have documented selection on behavioural responses that increase individual...

The apterous viviparous female and alate oviparous female of a new aphid species, Tamalia milleri sp. nov., a representative of a nearctic relict genus Tamalia and associated with Arctostaphylos columbiana, is described and figured in detail from specimens collected in California and Oregon (USA) and deposited in the Natural History Museum, London (UK). The differences between T. milleri and a ...

Antioxidants are abundant in blueberries, and while there are many studies concerning the bioactive compound of fruit, it is only recently that the wild Vaccinium species has attracted attention for their diverse and abundant chemical components. The aim of this study was to investigate the bioactive compounds of blueberry cultivars and wild species found in Japan. Among the five extracts of th...

Volatile compounds are responsible for the aroma and contribute to the flavor of fresh strawberries (Fragaria ×anannassa), red raspberries (Rubus idaeus), and blueberries (Vaccinium sp.). Strawberry aroma is composed predominately of esters, although alcohols, ketones, and aldehydes are also present in smaller quantities. The aroma of raspberries is composed of a mixture of ketones and terpenes...

Ann. Entomol. Soc. Am. 81(3): 419-427 (1988) ABSTRACT The anthophorid bee, Hahropoda (=Emphoropsis [R. W. Brooks, personal communication]) laboriosa (F.), is a locally abundant, vernal, univoltine species. It flies from February through April in Georgia and Alabama. In these states, females are oligolectic on Vaccinium spp., particularly V. ashei Reade and V. corymbosum L., with Gelsemium sempe...

The level of three major polypeptides of 65, 60, and 14 kD increased in response to chilling unit accumulation in floral buds of a woody perennial, blueberry (Vaccinium, section Cynaococcus). The level of the polypeptides increased most dramatically within 300 h of chilling and decreased to the prechilling level with the initiation of budbreak. Cold-hardiness levels were assessed for dormant bu...
