Analysis of Some Mineral Elements in Major Coconut Cultivars in Nigeria

Maimuna Waziri, Abdulrahman A. Audu, Fanika Suleiman


The mineral content of different cultivars of the endosperm tissues of coconut (Cocos nucifera Linn) samples commonly available in some parts of Nigeria were collected and analyzed for Fe, Zn, Ca and Mg by atomic absorption spectrophotometric techniques, while Na and K were determined by Flame photometric techniques. The mineral content of the coconut water ranged from 0.09 0.06µg/g Zn to 959.52 52.65µg/g Na while the mineral levels of the coconut meat ranged from 6.14  1.52µg/g Zn to 7809.53 436.41µg/g Na. The concentrations of the minerals were generally higher in the coconut meat than in the coconut water samples.  However, hybrid samples from Badagry, especially the larger nuts contained the highest levels of the minerals. The levels of Na, K and Ca suggest that health and nutritional benefits can be derived from consuming coconut water and coconut meat.
