    Bilberry (Vaccinium myrtillus L.) is rich in flavonoids (major part anthocyanins), tannins, phenolic and organic acids, and other biologically active compounds. Anthocianins possess a broad spectrum of therapeutic properties. Variation in anthocyanin content of bilberry fruit crude drugs is significant in optimizing collection conditions. Bilberry (Vaccinium myrtillus L.) crude drug samples were collected in July–September of 2006 in natural environment in the territory of Lithuania. Ultrasonic extraction was applied using methanol as solvent. Acidic hydrolysis was performed. Qualitative and quantitative composition of five major anthocyanidins (delphinidin, cyanidin, petunidin, peonidin, and malvidin) was estimated by high-performance liquid chromatography in frozen fruits. Cyanidin predominated in all crude drug samples. Dynamics of variation in qualitative and quantitative composition of anthocyanidins was estimated in bilberry fruits collected during vegetation period. The greatest total amount of all analyzed anthocyanidins was determined at the end of investigated period. Variation in qualitative and quantitative content of anthocyanidins in bilberry fruits collected in different regions of Lithuania was estimated as well. The greatest total amounts of anthocyanidins were found in samples collected in Krikštoniai forest (1.78%) and Prienai pinewood (2.13%) and the lowest amounts – in samples collected in Balkasodis forest (1.14%) and Ryliškės forest (0.99%). Significant variation in anthocyanidin content reaching 28.40% (delphinidin) was determined in bilberry fruits. It is important for the standardization of bilberry fruit crude drugs

    Qualitative and quantitative composition of anthocyanins in bilberry (Vaccinium myrtillus L.) fruits was assayed. The aim of our study was to evaluate total anthocyanin content and their composition in bilberries collected from various regions and at different time. For the quantification of total anthocyanins in frozen fruits, the spectrophotometrical assay was performed. The highest amount of anthocyanins in bilberry fruits, collected in Lithuania, was found in samples from Šilutė (0.399%), the lowest one – from Valkininkai region (0.264%), but higher amounts of anthocyanins were found in the samples collected in Russia (Archangelsk region) and Sweden (Stockholm region). High-performance liquid chromatography was applied for qualitative evaluation of individual anthocyanins in the different material. Quantification of anthocyanidin content was performed after acidic hydrolysis of anthocyanin glycosides. Chromatographic analysis has shown that there are no differences in qualitative composition of anthocyanidins. In all samples, cyanidin was found in the highest quantities (mean amount 0.053 µg/mL). Delphinidin and petunidin was found in quantities 2.5 fold lower than cyanidin, and malvidin and peonidin were found in the smallest quantities. Only in the blueberries collected in Sweden, malvidin was found in the highest amount. It was 1.5 fold higher than amounts of petunidin and delphinidin

    Products of lingonberries are widely used in the human diet; they are also promising beauty and health therapeutic candidates in the cosmetic and pharmaceutical industries. It is important to examine the sugar profile of these berries, due to potential deleterious health effects resulting from high sugar consumption. The aim of this study was to determine the composition of sugars in wild clones and cultivars or lower taxa of lingonberries by HPLC-ELSD method of analysis. Acceptable system suitability, linearity, limits of detection and quantification, precision, and accuracy of this analytical method were achieved. The same sugars with moderate amounts of fructose, glucose, and low amounts of sucrose were found in wild and cultivated lingonberries. Cultivar 'Erntekrone' and wild lingonberries collected from full sun, dry pine tree forests with lower altitude and latitude of the location, distinguished themselves with exclusive high contents of sugars. The changes in the sugar levels during the growing season were apparent in lingonberries and the highest amounts accumulated at the end of the vegetation. According to our findings, lingonberries seem to be an appropriate source of dietary sugars
