Abstract:

Fruit of Capsicum are among the most consumed spices throughout the world and are very important commercially. Plant bioactive compounds are increasingly gaining more attention because of their effectiveness in improving human health and nutrition. The sturdy was aimed at determining the phytochemical, mineral, and nutritional compositions of some selected Capsicum spp fruit. The study was conducted due to a lack of information on the chemical compositions of the selected fruit in Gombe.
The proximate, mineral, and nutritional compositions of the selected fruits (C. annum var. grossum, C. annum var. accuminatum, C. frutescens var. abbreviatum, and C. frutescens var. maxima) were analyzed using standard procedure. The phytochemical study revealed the present of alkaloid, flavonoid, saponin and steroid. Glycoside was present only in capsicum annum var. grossum while tannin was absent in all of the four varieties. The proximate values % of the fruits were moisture (85.10-80.57), Total ash (3.03-1.27), crude protein (3.72-2.45), crude fat (2.01-1.54), crude fiber (4.00-2.14), and carbohydrate (9.03-5.27). The results for mineral analysis were Magnesium (11.33-5.20), Manganese (9.67-0.77), Potassium (34.14-22.22), and Sodium (3.34-0.17) while copper was not detected in all four varieties.
The results indicated that these fruit used as a major condiment in the preparation of food can also have a therapeutic effect against several diseases, such as anti-oxidant properties by inhibiting the formation of free radicals in the body.
