Many forms of preserved tomato are today available in the market. They range from dried, canned juiced and some other forms. These are to ensure nonstop supply of the fruit throughout the year and to prevent spoilage. However, in many cases; when a food item is subjected to the preservation techniques, they tend to lose some nutrients compared to the fresh food item. The current study aimed at comparing the nutritional contents of canned and fresh tomato obtained from the market. Proximate, mineral and vitamin analysis conducted on three samples of canned tomato paste (C1, C2 and C3) and fresh tomato (Cf) show that, the fresh tomato has high percentage composition of moisture (93.8±3.00) and fat (0.62±0.08) than the three canned tomato. However, it has the least percentage composition of carbohydrate (2.52±0.01), protein (1.00±0.49), crude fibre (1.21±0.99) and ash (0.85±0.01) compared to canned tomato (p<0.05). When Mineral analysis was conducted, it indicate that sodium, potassium, and calcium concentrations are significantly higher in canned tomato (p<0.05), while the iron was found to be significantly higher in fresh tomato (p<0.05). Vitamin A content of fresh tomato is higher while that of vitamin C is higher in canned tomato.

Diabetes mellitus (DM) is a metabolic disease which results in elevated blood sugar levels. Kigelia africana plant has many medicinal properties due to the presence of numerous secondary metabolites. The aim of this research was to evaluate the acute toxicity profile and anti-hyperglycemic potential of methanol root extract of Kigelia africana on alloxan-induced diabetic rats. Twenty (20) 3-4 weeks old albino rats of mixed sexes with body weight 60-100 g were grouped into five groups (GI - GV) of equal number of rats. Diabetes was induced in the rats of Groups GII -GV, while GI rats were considered as non-diabetic control. GII which is the Diabetic control were received no treatment whereas, GIII were administered orally with 5 mg/kg b.w of standard anti-diabetic drugs Glibenclamide, GIV were orally administered 250 mg/kg b.w of extract and GV were orally administered 500 mg/kg b.w of extract. After 14 days of the treatments, the animals were sacrificed and their serum was analysed for lipid profile, hematological parameters, liver and kidney indices. At the end of the study, the root extract was found to posses’ anti-diabetic potential and due to less toxicity at low dose of about 500 mg/kg, the extract is believed to be safe for consumption at low dosage.
