Vaccinium myrtillus L. - Ericaceae - bilberry, whortleberry, European blueberry, Heidelbeere, Blaubeere

Summergreen erect shrub, 15-50cm high, native to Eurasia, northwestern North America; twigs with edges, green; leaves ovate, serrulate, pale green; flowers green-red; fruits blue to black.

„The volatile components of bilberry, bog blueberry and cultivated high-bush blueberry (cv. Rancocas) were analysed by gas chromatography and mass spectrometry. Several new compounds not reported previously as blueberry volatiles were detected. These included methyl and ethyl 2-hydroxy-3-methylbutanoate, methyl and ethyl 3-hydroxy-3-methylbutanoate, 2-phenylethyl formate, methyl salicylate, farnesol, farnesyl acetate, vanillin, myristicine, 4-vinylphenol, 2-methoxy-5-vinylphenol, citronellol, hydroxycitronellol and some γ- and δ-lactones. The character impact compounds of bilberry were found to be the above-mentioned hydroxy esters together with 2-phenylethanol and its esters and the γ- and δ-lactones, whereas myristicine, citronellol, hydroxycitronellol, farnesol and farnesyl acetate were typical of the aroma of high-bush blueberry.“

„As part of a project on cultivation and industrial exploitation of European Blueberry (Vaccinium myrtillus) started in 2008, berries from different wild populations from South, Mid and North Norway were investigated. One aspect of fruit quality analyses was to identify and describe blueberry aroma profiles. Volatiles were extracted by headspace solid-phase microextraction (HS-SPME) and analysed by gas chromatography/mass spectrometry (GC/MS). A total of 132 potential aroma volatiles could be detected, of which 99 structures were identified based on MS database search and retention indices, also comprising aroma impact compounds not being described in blueberries earlier. Detected aliphatic and aromatic structures belonged to different chemical groups such as alkanes, acids, alcohols, aldehydes, esters, ketones and mono- and sesquiterpenes. Ten major compounds (mostly C4-, C6- and C9-structures) accounted for averagely 65-75% relative amount of all detected peaks. However, HS-SPME analyses revealed complex volatile profiles including terpenes (23 compounds, e.g. p-cymene, 1,8-cineole, linalool) and aromatic structures (10 compounds, e.g. benzaldehyde, ethyl benzoate, 2-phenylethyl acetate, benzyl benzoate), which contribute to the characteristic and flavourful blueberry aroma.“

„Fruits and fruit extracts are recommended for treating diarrhea, especially in children. They are used locally to trat inflammation of the mucous membranes of the mouth and throat… The leaves are no longer recommended because prolonged use seemed to have toxic side effects… The main active ingredients are mosytly catechol tannins (up to 12%) and proanthocyanidines.“
