Cranberry Fruit Identity & Plant Part
The botanical entity is Vaccinium macrocarpon Aiton, the large or American cranberry, a low, creeping evergreen shrub of acidic North American bogs. The part used is the ripe fruit. Leaves, stems and seeds are not added separately to this cranberry extract, and neither the small cranberry Vaccinium oxycoccos nor the lingonberry Vaccinium vitis-idaea is used. Berries are harvested in autumn, many of them by flooding the bog so the fruit floats free.
Cranberry is easily confused with its relatives. Lingonberry is sold as “cranberry” in some regional markets, and blueberry and bilberry share the genus but carry a wider range of anthocyanins. The anthocyanins of the large cranberry are almost entirely cyanidin and peonidin glycosides, so a common name alone does not say which fruit is meant.
The fruit holds organic acids, chiefly citric, malic and quinic, along with flavonols, anthocyanins and A-type proanthocyanidins. They give cranberry its sharp acidity and astringency.
