What about blueberry:
There are three major blueberry types:
Highbush (V. Corymbosum L.)
Lowbush blueberry (V. Angustifolium Ation)
Bilberries (European blueberry, V. Myrtillus)
Lowbush blueberries are wild and are made up of many different clones that exhibit a great deal of phytochemical diversity (Kalt et al. 1996). The lowbush fruit is smaller than that of the highbush variety (Kalt et al. 1996). The functional components of Vaccinium products appear to be the phenolic compounds, particularly the anthocyanins (Mazza and Oomah, 2000). Extracts of the bilberry, V. Myrtillus, a type of European wild blueberry are widely used in prescription and over-the-counter medications (Kalt et al. 1994). There are currently over 180 Vaccinium pharmaceutical products available world wide. This type of medication has become increasingly popular, however the European crops cannot meet the global demand (Chein and Camire, 1996).
France, Italy, Germany, and Korea have been particularly active in the development of bilberry products. The anthocyanins of bilberries and North American wild blueberries are generally similar (Kult and Dufour, 1997). Pharmaceutical manufactures are now considering lowbush blueberry extracts as an alternative to the expensive V. Myrtillus extracts (Chein and Camire 1996).
