Aims: The study aimed to evaluate the nutritional and anti-nutritional factors composition of the Solanum torvum fruit. Place and Duration of Study: Department of Food Sciences and Technology, Biocatalysis and Bioprocessing laboratory of Nangui Abrogoua University (Côte d’Ivoire), between June 2019 and March 2020. Methodology: Proximate composition, mineral element profile and phytochemical composition of fresh and boiled S torvum berries were investigated. The S torvum fruit were harvested fresh. One part was cooked in boiling water for 25 min while the other part did not undergo any treatment. These two samples were dried in an oven at 45°C for 72 hours, ground and analyzed according to official analytical method. Results: The results indicated that the boiling caused the loss of nutrients except moisture, fibers and lipids. It was noted a significant reduction of nutrient and anti-nutrients content of berries after boiling. Boiled berries showed a higher energy value (57.07 Kcal) than fresh ones (53.12 Kcal). Despite the boiling, S torvum berries showed high levels of polyphenols (142.54 mg GAE/100g DW (dry weight)), carotenoids (12.96 mg βCE/100g DW), vitamin C (12.03 mg/100 g FW), fibers (6.88%) and ash (7.23%). Minerals analysis of S torvum berries indicated that it is rich in potassium (2046.77 mg/100 g DW), calcium (340.92 mg/100g DW), phosphorus (238.71 mg/100g DW) and magnesium (234.97 mg/100g DW) with high predicted bioavailability for calcium, magnesium and zinc. S torvum fruit contains also iron (7.97 mg/100g DW) and zinc (8.10 mg/100g DW) which are essential for organism. Conclusion: These data indicated that this Solanum torvum fruit consumed in East of Côte d’Ivoire could constitute a potential good source of nutrients for local population.

Valeur Nutritionnelle

En Afrique, de nombreuses espèces végétales ne sont pas suffisamment exploitées, malgré leurs valeurs comestibles indéniables. Parmi ces plantes figurent les aubergines amères Solanum anguivi Lam et Solanum torvum communément appelées "gnagnan" en Côte d'Ivoire. Les baies de ces légumes-fruits sont séchées et analysées selon des méthodes standard et conventionnelles. Le tri phytochimique a révélé que S. torvum contient plus de stérols, polyphénols, quinones et saponines par rapport à S. anguivi Lam. Aucune des deux aubergines ne contient d'alcaloïdes toxiques pour l'alimentation. En chromatographie sur couche mince, les sucres détectés sont le glucose, le xylose, l'arabinose et le saccharose. Cependant, le saccharose est remplacé par le fructose dans les baies de S. torvum. Ainsi, ces deux espèces pourraient être de bonnes substances naturelles avec une valeur nutritionnelle et médicinale intéressante. In Africa, many plant species are not sufficiently exploited, despite their undeniable edible values. Among these plants are the bitter eggplants Solanum anguivi Lam and S. torvum commonly called "gnagnan" in Côte d’Ivoire. Berries of these fruit vegetables are dried and analyzed according to standard and conventional methods. Phytochemical sorting revealed that S. torvum contains more sterols, polyphenols, quinones and saponins compared to S. anguivi Lam. Neither eggplant contains toxic alkaloids in the diet. In thin layer chromatography, the sugars detected are glucose, xylose, arabinose and sucrose. However, sucrose is replaced by fructose in the berries of S. torvum. Thus, these two species could be good natural substances with interesting nutritional and medicinal value.

Mushroom cultivation has been started in Côte d’Ivoire. Awareness of the nutritional and medicinal importance of mushrooms is not extensive. In this study, the nutritional values of dietary mushrooms Pleurotus ostreatus, that are very popular among the cultivated mushrooms in Côte d’Ivoire have been determined. The samples were obtained and analysed for proximate, mineral, vitamin, amino acids and fatty on dry weight basis using standard methods. These mushrooms were rich in minerals content (Cu= 36.35% ; Iron= 52.65 % ; Magnesium= 47.84 % ; Sodium= 14.50%) and contained a lower amount of calcium (9.85%), phosphorus, potassium, and zinc. We also note the presence of vitamin A (0.19%), vitamin C (17.48%) and those of group B (B1, B2, B3, B6 and B9). The amino acids contents ranged from 1.17% for alanine and lysine, 1.7 % for leucine and 0.07% to serine. The mushrooms are rich in lipid with the presence of linoleic acid, linolenic acid, oleic acid, palmitic acid and stearic acid. Data of this study suggest that mushrooms are rich in nutritional value.

Les populations de la ville de Daloa en Côte d’Ivoire consomment majoritairement les eaux de forages au détriment de l’eau fournie par la société agréée. Ainsi, cette étude des eaux de forages a pour objectif l’évaluation de ses caractéristiques physico-chimiques. Elle a permis de mesurer au niveau de quinze forages les paramètres tels que le pH, la conductivité électrique, la température, le nitrite, le nitrate, l’ammonium, le sulfate, le bicarbonate, le calcium, le magnésium et le potassium. Les valeurs moyennes sont comparées aux normes relatives à la qualité de l’eau de boisson. L’analyse statistique multivariée dont l’Analyse en Composantes Principales (ACP) et la Classification Hiérarchique Ascendante (CHA) a été également appliquée à l’ensemble des paramètres mesurés. Il ressort des résultats que l’eau des forages est légèrement acide avec un pH moyen de 6,0 ± 0,5. Elle est faiblement minéralisée avec une conductivité électrique moyenne de 246,2 ± 162,6 μS/cm. Une forte corrélation est signalée entre la conductivité électrique et les paramètres suivants : nitrate, ammonium, bicarbonate, calcium, magnésium, sodium et potassium. La classification des forages est gouvernée par les valeurs de conductivité et de pH qui permettent de regrouper les forages selon leur qualité physico-chimique. Les eaux des forages de Daloa sont conformes aux directives de l’OMS.Mots clés : Daloa, eau de forage, norme, paramètres physico-chimique, qualité de l’eau. English title: Physicochemical characteristic of ground water for domestic use in the town of Daloa (Midwest, Ivory Coast)   The population of Daloa (third largest city in Côte d’Ivoire) mainly consume borehole water to the detriment of water provided by approved company. Thus, the quality of borehole water is evaluated from their physicochemical characteristics in this study. The study carried out in various districts of the city made it possible to measure for fifteen boreholes the physicochemical parameters such as pH, electric conductivity, temperature, nitrite, nitrate, ammonium, sulphate, bicarbonate, calcium, magnesium and potassium. The average values are compared with the standards relating to drinking water quality. The Multivariate statistical analysis whose Principal Components Analysis (PCA) and hierarchical clustering (HC) were also applied to the whole of the measured parameters. The results show that the borehole water is slightly acid with an average pH of 6,0 ± 0,5. It is slightly mineral-bearing with an average electric conductivity of 246,2 ± 162,6 μS/cm. A strong correlation is announced between electric conductivity and the following parameters: nitrate, ammonium, bicarbonate, calcium, magnesium, sodium and potassium. The classification of borehole controlled by this value of conductivity and pH which makes it possible to gather borehole according to their physicochemical quality. The physicochemical parameters of borehole water from Daloa are in conformity with the directives of WHO.Keywords: Daloa, borehole water, standard, physicochemical parameters, water quality.

Six okra varieties (F1 Yodana, Kirikou, Volta, Yeleen, Kousko and Local) sold and consumed in Daloa (Côte d’Ivoire) were evaluated with regards to the nutritional, antioxidant and mineral contents. The result of the study revealed that the proximate composition in dry weight basis was significantly (P < 0.05) varied and ranged: dry matter 87.83-92.33%, crude protein 13.65-22.63%, crude fat 2.78-3.94%, crude fiber 21.08-26.70%, crude ash 7.16-10.59%, carbohydrate 39.28-54.25%, and energy value 274.78-297.97 kcal/100 g. Volta had the highest content in both protein and fat. Yeleen had the highest ash content, Local had the highest fiber content, while Kirikou presented the highest content in both carbohydrate and energy values. The phenolic content ranges from 111.42 to 156.00 mg/100 g while the vitamin C ranges from 25.30 to 49.60 mg/100 g in dry weight basis. Volta had the highest content in both phenolic and vitamin C. The mineral contents (mg/100 g) in dry weight basis were also significantly (P < 0.05) varied. Potassium was the most abundant macro-element (1642.71-2519.84) followed by calcium (460.80-767.72), magnesium (345.46-432.70) and Iron (0.42-3.18) in all the varieties. Interrelationships between the parameters analysed and the different okra varieties were investigated by principal component analysis (PCA). PCA revealed differences between the okra varieties and classified them into three groups on the basis of the measured parameters: Group 1 (F1 Yodana, Volta and Local), Group 2 (Kirikou and Kousko) and Group 3 (Yeleen). This study provided important information about the nutritional composition of okra from Daloa, which can help to increase production and consumption of these nutrient-rich vegetables and will help reduce the nutrition-related disorders in Africa.
