The nutritional compositions of selected green leafy vegetables obtained from major towns in Oyo State, Nigeria, (March and April) were determined using standard analytical methods for proximate analysis. The following nutrients in percentage were determined; moisture contents, ash, fat, crude fibre and crude protein. The green leafy vegetable used are Talium triangulare, Amaranthus hybridus, Launaena taraxacifolia Ocimum gratissimum, Celosia argentea, Cucuribita maxima, Abelimoschus esculentus, Solanum macrocarpon, Vernonia amygdalina and Sesamum indicum. All nutrients were present in appreciable quantities. Moisture contents ranged from 5.33 ± 0.06% - 8.33 ± 0.06%, ash (23.07 ± 0.06% - 61.27 ± 0.06%), fat (1.13 ± 0.06% - 3.37 ± 0.06%), crude fibre (2.43 ± 0.12% - 22.03 ± 0.06%), and crude protein (18.50 ± 0.10% - 55.23 ± 0.06%). The functional properties of vegetables were close in term of high protein level indicating that they are more nutritious. Also, the level of their ash content showed that the vegetables are very rich in essential minerals for healthy life when compared with one another and recommended dietary allowance (RDA). Thus, there is a need for farmers in the area to engage in dry season vegetable production so as to ensure availability of leafy vegetables throughout the year.
properties have been linked to incidences of overweight and obesity [10,11]. Moderate adjustment involving dietary fibre have shown promise in promoting weight loss and reduced risk of chronic diseases in humans [12,13]. In the light of the foregoing, there is need to explore available dietary staples in the formulation and use of a flour base close to or with an optimum dietary fibre ratio (IDF/SDF) (2:1). Ofada rice (Oryza sativa L) and unripe plantain (Musa Paradisiaca AAB) fruit (sometimes called cooking bananas) -two staples in the sub-saharan region of Africa, holds promise in these respects.Ofada rice had been classified as a peculiar form of Oryza sativa species [14]. It is an unpolished short grain upland rice high in fibre (3.5%
Aim: This study was designed to determine Aflatoxins present in kola nuts sold in Ibadan metropolis.
Study design: Kola nuts were randomly purchased from different markets in Ibadan, Oyo State.
Methodology: Thin layer chromatography (TLC) and spectrophotometric method were used for the determination of aflatoxins in the kola nuts samples.
Results: All the samples collected were contaminated with aflatoxins. Aflatoxin B1 and B2 were present in the kola nuts samples ranging from 9.73 - 25.43 μg/kg and 10.90 - 29.67 μg/kg respectively.
Conclusion: The levels of aflatoxins in the sampled kola nuts were mostly above recommended tolerable limits. It is imperative to enlighten stakeholders on possible ways of handling kola nuts towards reducing the aflatoxin incidences to the barest minimum in order to safeguard the health of the populace.
The proximate, minerals, and phytochemical composition of Ocimum gratissimum plant (OGP) that grew with different manure were investigated. OGseeds were planted in experimental plots in a Randomized Complete Block Design (RCBD) laid out in Oyo State College of Agriculture, Igboora with three replicates having plot size 3 m x 3 m of four treatments namely; Treatment A-No fertilizer or manure -(control), B-Poultry manure, C-N:P:K 15:15:15 and D-Compost manure respectively. Other parameters studied were planted height, leave areas, number of leaves and plant girth. The pre-soil test carried out indicated that the soil had organic matter (OM) content of 1.56%, total N 0.11% and available P 16.92 mg/g. This low level of nutrients justified the need for fertilizer
