Hibiscus sabdariffa commonly known as “roselle” is a member of malvaceae family. It is a plant with a worldwide fame and has more than three hundred species which are distributed in tropical and subtropical regions around the world. Many parts of Roselle including seeds, leaves, fruits and roots are used in various foods as well as in herbal medicine. This research work analyzes the nutritional composition of dried Hibiscus sabdariffa leaves and calyces. The moisture content was determined by exposing the sample to heat under controlled conditions, the water from the material evaporated leaving the dry matter. The ash content was determined by burning off the organic matter leaving behind inorganic ash. Base on the principle that non-polar components of samples are easily extracted into organic solvent, crude lipid was determined using n-Hexane. The protein content was obtained by Kjeldahl method. Mineral analysis was also carried out to determine the amount of Potassium, calcium and phosphorus. The result shows that the dried leaves and calyces of Hibiscus sabdariffa contain: Moisture: 12.50% and 10.50%, Ash: 14.50% and 11.67%, fibre: 0.83% and 1.17%, Crude lipid: 4.33% and 1.00%, Crude protein: 5.37% and 4.10% respectively. The mineral content of the leaves and calyces were; Calcium: 1.40% and 1.20%, Magnesium (mg/g): 1.35% and 1.57%, Phosphorus: 5.00% and 5.485% respectively. The leaves, of the plant can be used as vegetable to make soup and other dishes, Drinks made from Roselle calyces should be consumed regularly as it is safe, natural and nutritious.
