 In southern parts of West Africa, the most commonly consumed species is C. acuminata and C. nitida is preferred in northern parts. For example, C. acuminata is the preferred species in western Cameroon and its trade is limited to this region. C. nitida, however, is produced though generally not consumed in this region; what is collected is traded to the North." \\

 "Coca-Cola syrup does not contain any kola nut extract. Since no kola extracts are present in the recipe, the primary taste of Coca-Cola comes from vanilla and cinnamon with trace amounts of orange, lime and lemon and spices such as nutmeg." [[https://en.wikipedia.org/wiki/Coca-Cola_formula]]
+Cola seeds contain [[https://en.wikipedia.org/wiki/Xanthine|xanthines]] with caffeine as major compound. The average concentration of caffeine found in C.acuminata seeds was 1.1% (C.nitida 1.3%, C.anomala 0.7%). \\

 "The seeds are chewed as a stimulating narcotic, beverage could be made by boiling powdered seed in water, and also a cough syrup made from the juice extract (Tachie-Obeng and Browns, 2004, http://carpe.Umd.Edu/Documents/2001/report-tachieobeng_brown2001.pdf). The stem and twig wood is used for chewing stick. It can also be used as flavoring in soft drinks e.g. coca-cola. Several species of cola nut have been recognised in Nigeria. There are about three sub genera that are accepted and cultivated. They are often refers to as edible cola but only two are widely cultivated namely Cola nitida (Vent.) Schott and Endl and Cola acuminata (P. Beauv.) Schott and Endl they are the two economically important members of the cola genus. They are bitter-tasting nuts known conventionally as Kola nuts. These two species are the true cola nuts. In Western Nigeria, cola nut ranks very high among agricultural cash crops in importance from which the bulk of our revenue can be derived." \\
