Abstract: The hydrogen cyanide contents of Manihort utilissima (Cassava), Colocasia esculenta (Coco yam), Dioscorea bulbifera (Aerial yam) and Dioscorea domentorum (Trifoliate yam) Tubers found in Benue State were determined in their fresh and dried forms. The amount of hydrogen cyanide found in the fresh state was 304.60 mg 100g-1, 34.10 mg 100g-1, 49.70 mg 100g-1 and 79.40 mg 100g-1 for Manihort utilissima, Colocasia esculenta, Dioscorea bulbifera and Dioscorea domementeroum respectively; while the amount observed in the dry form was 249.50 mg 100g-1, 17.30 mg 100g-1, 32.50 mg 1200g-1 and 55.10 mg 100g-1 for Manihort utilissima, Colocasia esculenta, Dioscorea bulbifera and Dioscorea domementeroum respectively. Higher hydrogen cyanide contents were observed in the fresh samples than the dried samples. Manihort utilissima was found to have the highest values both in the fresh and the dried forms. Statistical analysis of the mean values of hydrogen cyanide content of the tubers indicates a significant difference between the fresh and the dried forms of the tubers. The study revealed that tubers of these plants have relatively high content of hydrogen cyanide content.

Journal of Food Technology , 2013,
Abstract: 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.

American Journal of Food Technology , 2011,
Abstract: Tacca leontopetaloides tubers are known to be a staple food of inhabitants of the area under study, however, the peels have been found to be poisonous to livestock and other animals that feed on them. This study therefore, is aimed at investigating the nutrients and antinutritional factors in order to ascertain their composition in the peels. The peels were collected from Utange and Mbachegh wards in Katsina-Ala Local Government Area and Mbaatikyaa ward in Buruku Local Government Area of Benue State, Nigeria and were labeled as sample A, B and C respectively. The moisture, ash, Crude lipids, crude protein and carbohydrates analysis were determined. Anti-nutritional factors like phytate, oxalate, cyanogenic glycosides and saponins were also determined. Results of the analysis indicate the moisture content to be 18.58, 15.40 and 28.38% for samples A, B and C, respectively. Ash content of the peels was found to be 4.13, 9.60 and 5.13% for samples A, B and C, respectively. Lipids content of the samples was found to be 3.80, 2.85 and 1.10% for A, B and C, respectively. The amount of fibre in sample A, B and C was found to be 2.06, 2.07 and 1.10%, respectively while 0.21, 00.07 and 00.18% was obtained as the protein content of the peels, respectively. The result of carbohydrates was found to be 71.20, 69.35 and 62.94 for the three samples, respectively. Results of anti-nutrition indicate the levels of Cyanogenic glycoside to be high (45.00, 43.00 and 44.00 mg kg-1). Saponin content of the peels was found to be 35.00, 31.50 and 34.50 mg kg-1. Phytate in the sample to range between 28.50-29.50 mg kg-1, while Haemogglutinin and oxalate were found to be 20.00-23.00, 16.50, 19.00 and 15.50 mg kg-1 for samples A, B and C, respectively. Tacca leontopetaloides peels though has high content of carbohydrates, it is not suitable for consumption because of the high anti-nutritional factors.

Journal of Biological Sciences , 2004,
Abstract: 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.

Journal of Food Technology , 2013,
Abstract: 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.

Abstract: The sexually Transmitted Diseases constitute major public health problems in Nigeria. There is early sexual maturity and considerable sexual activity between 9 and 15 years of age. Although there is a high awareness of the condom, people are unwilling to use them despite evidence of multiple sexual exposures. The STDs, including HIV infections, are on the increase. Tuberculosis is also on the increase because of a HIV/AIDS epidemic. Both categorical and integrated approach to the management of STDs and AIDS are being recommended. There is a need to step up basic research into the biology of HIV and subsidize the treatment of AIDS. Efforts at vaccine development should be initiated to stem the worsening HIV epidemic. (Af.
