  The seeds of Moringa oleifera Lam (family: Moringaceae) and Detarium microcarpum Guill and Sperr (family: Caesalpiniodeae) were analysed for nutritional and antinutritional contents and chemical properties of the oils extracted from the seeds were also determined. The concentrations (mg g-1) of the essential elements, potassium, calcium, magnesium, sodium, sulphur, phosphorus and iron were 77.4, 20.50, 1.19, 2.999, 3.75, 1.365 and 1.4, respectively for M. oleifera and 105.00, 23.0, 0.22, 2.36,16.25, 1.25 and 3.12 for D. microcarpum, respectively. Moringa oleifera contained higher amount of proteins and lipids (40.19 and 41.58%, respectively) than in D. microcarpum that contained 11.24 and 35.94% of protein and lipids, respectively. The amount of carbohydrate was highest in Detarium microcarpum (42.20%) than M. oleifera (9.11%). Moringa oleifera contained higher concentration of phytate (10.18 mg/100 g), hydrogen cyanide (0.58 mg/100 g) and saponin (2.052%) than D. microcarpum. The iodine values of the oils in M. oleifera and D. microcarpum were 59.48 and 58.02, respectively. Saponification values were in the range of 179-220.66. The acid value, free fatty acid and peroxide values were low (less than 9.0). The ester values of the oils ranged from 173.57-212.54. The high elemental composition, protein, lipid and carbohydrate contents of the seeds suggests that they could serve as supplementary sources of essential nutrients to man and livestock, provided the anti-nutritional content of the seeds are considerably reduced or eliminated.

  The seeds of Moringa oleifera (Lam.) Detarium microcarpum (Guill and Perr) and Bauhinia monandra (Kurz.) were analysed for essential, essential trace and non-essential elements. Detarium microcarpum had high amount of potassium (105 mg gG ), sulphur (1.63 mg gG ) and iron (3.12 mg gG ), while B. monandra had high amount of calcium (77.9 mg gG) magnesium (2.87 mg gG ) and phosphorus (1.59 mg gG ) sodium concentration as highest (2.999 mg gG ) in M. oleifera. The concentration 1 1 of essential trace elements in the seeds varied, the iodine (5.42 mg gG ) was found to be 1 highest in D. microcarpum and the lowest was molybdenum (0.011 mg gG ) in M. oleifera. The concentration of the non-essential and rare earth elements (arsenic, lead, tin, nickel, bromine, vanadium, cobalt, rubidium, strontium, yttrium, zirconium, thallium and niobium) were found to be low (<0.70 mg gG ) in 1 the three seeds. The concentration of thallium was 1.10, 1.96 and 1.69 mg gG in M. oleifera, 1 D. microcarpum and B. monandra, respectively. The results indicate that the mineral contents of these wild plants are comparable with average values of common fruits and seeds. Therefore, they could serve as supplementary sources of mineral nutrients for man and livestock.

  Musa sapientum peels were analysed for minerals, nutritional and anti-nutritional contents. The result of mineral content indicate the concentrations (mg g 1) of potassium, calcium, sodium, iron, manganese, bromine, rubium, strontium, zirconium and niobium to be 78.10, 19.20, 24.30, 0.61, 76.20, 0.04, 0.21, 0.03, 0.02 and 0.02, respectively. The percentage concentrations of protein, crude lipid, carbohydrate and crude fibre were 0.90, 1.70, 59.00 and 31.70, respectively. The results indicate that if the peels are properly exploited and process, they could be a high-quality and cheap source of carbohydrates and minerals for livestock.

  Aluminium (Al) is well known to be a toxic metal, particularly in patients with chronic renal dysfunctions. It is therefore, crucial to determine the levels of the element in dietary matrices with a view to estimating the daily dietary intake. In the present research, the total content of Al from different sources is present. Analytical technique employed is Graphite Furnace Atomic Absorption Spectrometry (GFAAS). Samples analyzed were beef baked in Aluminium foil, drugs (tablets) and beverages. Results indicate Al in the range 59.83-220.20 mg kg-1 baking duration 60-180 min beef, 1.05-1.42 mg g-1 drugs and 0.171-0.481 mg g-1 for both bottled and Al canned beverages. The standard deviation of the means is from ±1.31 -±69.54, ±0.055 -±0.187 and ±0.105 -±0.117; baked beef, drugs and beverages, respectively. Al content is lower than the daily dietary intake of 60 mg for an average body weight of 60 kg as set by WHO/FAO as tolerable based on product packaging/serving or doses normally prescribed. However, a pool of the metal from all the sources investigated and other sources may significantly increase the daily dietary intake above the WHO/FAO specification, which may become deleterious to health.
