What is Bilberry?
Bilberries are any of several primarily Eurasian species of low-growing shrubs in the genus Vaccinium (family Ericaceae), bearing edible, nearly black berries. The species most often referred to is Vaccinium myrtillus L., but there are several other closely related species. Bilberries are distinct from blueberries but closely related to them.
Bilberries are found in acidic, nutrient-poor soils throughout the temperate and subarctic regions of the world. They are closely related to North American wild and cultivated blueberries and huckleberries in the genus Vaccinium. One characteristic of bilberries is that they produce single or paired berries on the bush instead of clusters, as the blueberry does. Blueberries have more evergreen leaves.
What is Anthocyanins?
Anthocyanins (also anthocyans; from Greek: ἀνθός (anthos) = flower + κυανός (kyanos) = blue) are water-soluble vacuolar pigments that may appear red, purple, or blue depending on the pH. They belong to a parent class of molecules called flavonoids synthesized via the phenylpropanoid pathway; they are odorless and nearly flavorless, contributing to taste as a moderately astringent sensation. Anthocyanins occur in all tissues of higher plants, including leaves, stems, roots, flowers, and fruits. Anthoxanthins are clear, white to yellow counterparts of anthocyanins occurring in plants. Anthocyanins are derived from anthocyanidins by adding sugars.
