Abstract: The seeds of Hibiscus sabdariffa were analysed for nutritional and anti-nutritional factors. The concentration (mg g-1) of minerals indicates potassium to be the highest 1505.0. Magnesium and calcium were 322.2 and 218.2 (mg g-1) respectively. The concentration (mg g-1) of sodium, aluminium, manganese and chlorine were 12.5, 46.6, 7.6 and 24.5 respectively. Protein, lipid, soluble carbohydrate and fibre contents were 19.84, 28.10 33.0 and 6.33% respectively. The result of anti-nutritional factors indicates that the concentration (mg 100 g-1) of phytate, hydrogen cyanide and trypsin inhibitory activity were 5.90, 0.29 and 9.23, respectively. Tannins and saponin contents were 0.16 and 2.20% respectively. The result of the analysis showed that the seeds of Hibiscus sabdariffa could serve as a good food supplement for man and livestock if further processing methods are employ to eliminate the little toxicant inherent in the seeds.
