LG Hassan, SW Hassan, T Hashim, KJ Umar, NA Sani
Bayero Journal of Pure and Applied Sciences , 2011,
Abstract: The focus of this study was to investigate the nutritional values of Lepidium sativum leaves, a vegetable commonly consumed by the people of North-Western Nigeria. Sample of L. sativum leaves were collected from different farm lands at More town, Kware Local Government Area of Sokoto State. The leaves were dried then subjected to proximate, amino acids, minerals and antinutritional analyses. The results of proximate analysis indicate that the leaves had high crude protein (18.25%), crude fibre (9.31%) and ash (15.38%). The minera ls assay showed that the leaves are particularly high in potassium (1850.00 mg/100g), calcium (829.13 mg/100g), magnesium (160.60 mg/100g), sodium (141.13 mg/100g) and iron (63.47 mg/100g) with low level of phosphorus (4.10 mg/100g), manganese (5.74 mg/100g), copper (0.39 mg/100g) and chromium (0.36 mg/100g). The amino acid profile revealed that the leaf protein is generally low in lysine, sulphur containing amino acids (methionine and cystein), and threonine. Lysine was the most limiting amino acid in the leaves. In terms of antinutritional factors, the leaves had low concentrations of phytate (10.95 mg/100g), nitrate (0.05 mg/100g) and HCN (31.54mg/100g) with moderate amount of oxalate (337.50 mg/100g). Based on these nutrient contents, the leafy vegetable will have potential benefits as part of feeding programmes, as well as their promotion as part of composite die.

Bayero Journal of Pure and Applied Sciences , 2011,
Abstract: The non-edible vegetable oils of Jatropha curcas, neem, castor, rubber and edible oils of soyabean and cotton were investigated for their use as biodiesel feedstock. The analysis of different oil properties, fuel properties of non-edible and edible vegetable oils were investigated in detail. A two-step and transesterification process was used to produce biodiesel from high free fatty acid (FFA) non-edible oils and edible vegetable oils respectively. This process gives yields of 96.1 – 98.5 % of biodiesel using potassium hydroxide (KOH) as a catalyst. The fuel properties of biodiesel produced were compared with diesel. The properties of the oils analysed showed that biodiesel from non-edible and edible vegetable oil are comparable with ASTM biodiesel standards and is quiet suitable as an alternative to diesel.

Nigerian Journal of Basic and Applied Sciences , 2011,
Abstract: Nutritional and antinutritional contents of Parkia biglobosa flower were analysed using standard analytical methods. On dry weight basis, the flower had the following proximate compositions; ash (6.50 ± 1.00%), crude lipid (4.66 ± 0.29%), crude protein (6.77 ± 0.15%), available carbohydrate (78.9 ± 1.18%) and crude fibre (3.17 ± 0.29%). The calorific value was 384.7 kcal/100g. Mineral analysis indicates that the flower contain some essential minerals such as K, Na, Ca, Mg, and Zn, but was low in Cu, Mn, and Fe. The flower has low concentration of anti-nutritive factors: phytate (1.41±0.24mg %); oxalate (0.03±0.01mg %); hydrocyanic acid (0.17±0.01mg %) and nitrate (1.32±0.10mg %). The values are below the reference toxic standard levels. Therefore, P. biglobosa flower could supplement the microelements requirement, energy and to some extent protein.

MA Sokoto, LG Hassan, SM Dangoggo, HG Ahmad, A Uba
Nigerian Journal of Basic and Applied Sciences , 2011,
Abstract: Oil extracted from the seeds of Curcubita pepo was transesterified using potassium hydroxide in methanol. Fatty acid methyl esters (FAME) profile of the produced diesel was analyzed using Gas chromatograph coupled with mass spectrophotometer (GC-MS). The results indicate the presence of methyl (12E)-octadecenotate as the dominant ester with approximate percentage by composition of 82.90%. Other esters detected were methyl tetradecanoate (0.4%), methyl eicosonoate (2.48%), methyl docosanoate (0.97%) methyl teracosanoate (0.47%). Some critical fuel parameters like oxidation stability, cetane number, iodine value and viscosity were correlated with the methyl ester composition and structural configuration. It was found that the cetane number and oxidation stability of the produced biodiesel is a function of the degree of unsaturation and long chain saturated factor. The profile of methyl esters in the biodiesel produced indicates its likelihood to be a viable fuel source for internal combustion engines.

S Muhammad, LG Hassan, SM Dangoggo, SW Hassan, KJ Umar, RU Aliyu
Science World Journal , 2011,
Abstract: Sclerocarya birrea fruits are widely eaten in developing countries especially in rural areas and serves as nutrients supplements. However, they also contain phyto-toxin which may affect the normal functioning of the body. Acute toxicity was performed by a single oral administration at a dose of 3000 mg/kg body weight. Sub chronic evaluation was done by oral feeding of the rats with the seed kernel extract daily at doses of 1000, 2000, 3000 and 4000 mg/kg body weight for 28 days. The results of acute toxicity showed no mortality and general behavior changes. The lethal dosage (LD50) was greater than 3000 mg/kg body weight. Rats fed with 1000 and 2000 mg/kg body weight of the extract showed increased body weights throughout the period of treatment but not significantly (p<0.05) different from the control group. Significant (p<0.05) reduction in the body weights were noticed in those administered with 3000 and 4000 mg/kg body weight at the 4th and all the weeks respectively. Significant (p<0.05) increased in serum total protein, albumin, bilirubin, transaminases, creatinine, urea, uric acid and electrolytes were observed in rats fed with 3000 to 4000 mg/kg body weight of the extract, suggesting liver and kidney toxicity. Therefore, the seed kernel extract of S. birrea may be relatively toxic at doses of 3000 and 4000 mg/kg body weight.
