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) .
