“…These values are calcium, 2.59mg/100g dry matter white nut to 3.09mg/100g dry matter for pink nut; potassium, 10.61mg/100g dry matter for white nut to 12.12mg/100g dry matter for red nut; sodium, 3.23mg/100g dry matter pink nut to 4.66mg/100g dry matter for red nut; phosphorus, 4.81mg/100g dry matter for white nut to 6.06mg/100g dry matter for red nut; magnesium, 3.21mg/100g dry matter for white nut to 4.62mg/100g dry matter for red nut; iron, 2.92mg/100g dry matter for white nuts to 3.27mg/100g dry matter for red nut; zinc, 2.32mg/100g dry matter for white nut to 3.05mg/100g dry matter for red nut and manganese, 3.02mg/100g dry matter for white nut to 3.88mg/100g dry matter for red nut respectively (Table 3). The result obtained from this study compared favorably with that reported by other Workers (Jayeola, 2001). Similar distribution of mineral elements was observed in V .volvacea and P. tuber-regium (Kuforiji, 2005).…”

“…The crop is important because of its nut ("Obi") that has important pharmacological properties (Atawodi et al, 2007) and also contains some active principles found in coffee and cocoa (caffeine, theobromine, kolatin) (Opeke, 2005) which prevents sleep, thirst and hunger and also acts as an antidepressant (Mokwunye, 2009). Jayeola (2001) reported the possible use of kola nut for the production of soft drinks.…”

The aim of this work was to determine the effect of different botanicals on proximate, minerals and anti-nutrient composition of kola nut in respect to length of storage at 3 weeks after curing. Different classes of weight, 1-10, 11-20 and 21-40g and colours of C. nitida nut were collected from "Ogunmakin market" Ogun state. The nuts in a basket were lined up with different botanicals while justoxin was used as a standard. The nuts of the different sizes and colours were crushed separately into smaller particle sizes using perforated grater for analysis. Nutritive and anti-nutrient evaluation were investigated. Significant difference was obtained for potassium, magnesium and zinc with Potassium having the highest in all the elements analyzed with value 11.69mg/100g dry matter when treated with T. grandis, followed by phosphorus with value 5.57mg/100g dry matter when treated with A. indica and the least was observed for zinc with value 2.50mg/100g dry matter when treated with justoxin respectively. There was significant increase in all the mineral elements analyzed from the lowest nut weight (smallest size) to the highest nut weight (highest size) with the preponderance of potassium (K). Red nut had the highest in all the mineral elements analyzed except for calcium and was highly significant. Oxalate had the highest value ranged between 1.78mg/100g dry matter to 3.09mg/100g dry matter, followed by trypsin inhibitor ranged between 1.33mg/100g dry matter to 2.06mg/100g dry matter and phytate the least ranged between 1.30mg/100g dry matter to 2.03mg/100g dry matter respectively. All the anti-nutrient analyzed was significantly different from each other at 5% level of probability. Significant difference were obtained for % crude protein, moisture content, organic carbon and organic matter ranged between 3.34 to 3.49 for crude protein, 88.17 to 88.79 for % moisture content, 5.52 to 5.70 for % organic carbon and 9.46 to 9.80 for % organic matter respectively. Result obtained for proximate of different weight showed increased values from the lowest nut weight to highest nut weight. These results reveal that these seeds/nuts contain appreciable amounts of nutrients especially carbohydrates and proteins with good caloric value and low levels of toxicants and should be included in human diets to supplement our daily allowance needed by the body.

“…Its fruits contain seeds known as kolanuts. The nuts are consumed by humans in different part of the world because of its stimulatory properties (Jayeola, 2001). Kolanuts are used as gesture of peace, friendship, hospitality and it is important in various social ceremonies and religious activities (Purgesleve, 1977;Hatasaka et al, 2001).…”

In this study, gas chromatography-mass spectrometry (GC/MS) was used to analyse the isolated caffeine from kolanut and deternine the acute and chronic toxicity of the extract and the isolated caffeine. In chronic toxicity test, rats were divided into five groups (10 rats per group). Each rat was administered with normal saline (control group), crude kolanut extract (11.9 mg/kg), isolated caffeine (7.5 mg/kg), synthetic caffeine (6 mg/kg) or (6 mg/kg) decaffeinated kolanut extract orally for 90 days. Biochemical assessment and body weight of the rats were determined. In acute test, the limit test dose of 2000 mg/kg was administered to the rat and observed for 48 h post treatment. This dose caused behavioural changes but did not cause mortality in the rats tested. The results of the chronic administration showed that caffeine significantly (P < 0.05) decreased body weight. Liver enzymes were significantly (P < 0.05) increase, total plasma protein levels, creatinine, bilirubin, very low density lipoprotein (VLDL), low density lipoprotein (LDL) and total serum cholesterol levels were also significantly (P < 0.05) higher. However, urea was significantly (P < 0.05) lower in the caffeine treated groups. The results of the GC-MS analysis showed that the isolated caffeine from kolanut extract contains 82.69% pure caffeine with 96% in quality. Our results showed that the kolanut extract is rich in high quality caffeine and chronic consumption of it is associated with significant toxic effects as shown by elevated biochemical parameters, and reduction in body weight.

“…Kolanuts are often used to treat whooping cough and asthma. The caffeine present acts as a bronchodilator, expanding the bronchial air passages (Jayeola, 2001;Kim, 2001). Kolanuts are also employed in the treatment of malaria and fever (Odugbemi, 2006).…”

The in-vitro antimicrobial evaluation of ethanol extracts of four species of Cola Schott & Endl. was done using human isolated strains of Staphylococcus aureus, Staphylococcus albus, Bacillus subtilis, Klebsiella pneumonia, Pseudomonas aeruginosa, Candida albicans, Aspergillus niger as test organisms. The assays were carried out by agar well diffusion, erythromycin and ketoconazole served as the control drugs. The leaf ethanol extracts of the plants were found to be more effective against the tested fungi than the bacteria at high concentrations. None of the extracts was active against Staphylococcus aureus. Plant extract of C. acuminata (P. Beauv.) Schott & Endl. and C. nitida (Vent) Schott & Endl. showed activity on S. albus at concentrations ranging from 10-150 mgmlˉ¹ having comparable diameters of zone of inhibition of 7.3±0.03-16.0±0.0 for C. acuminata and 10.0±0.0-19.0±0.0 for C. nitida. Also, these two species of Cola demonstrated activities on C. albicans and A. niger at concentrations ranging from 90-150mgmlˉ¹ with relatively close diameters of zone of inhibition. Only C. acuminata inhibited the growth of K. pneumoniae at the MIC of 90mgmlˉ¹ whereas, C. albicans was inhibited by C. acuminata, C. millenii K. Schum and C. gigantea A.Chev. at the MIC of 120mgmlˉ¹. Phytochemical screening of the four species of Cola showed the presence of alkaloids, saponins, tannins and cardenolides in all the plants which apart from showing the probable closeness of the species could also be responsible for the observed activities. The antimicrobial property shown by the plant extracts is an evidence of the ethnomedicinal uses of the plants. The similarity observed in the phytochemical constituents and antimicrobial activities demonstrated by C nitida (Vent.) Schott & Endl., C. millenii and C.gigantea A. Chev. and C. acuminata suggest a probable closeness among these species. The results obtained in this study provide preliminary evidence of the chemotaxonomic significance of secondary metabolites and antimicrobial activities in infra-generic taxonomy of species of Cola.
