Ce travail évalue l’importance socio-économique d’Irvingia gabonensis (Irvingiaceae) ou le manguier sauvage dans la région de l’Agnéby-Tiassa dans le sud de la Côte d’Ivoire. À cet effet, un inventaire de la population a été réalisé dans les zones agroforestières en particulier dans les cacaoyères afin de déterminer la perception de cette espèce par cinq groupes socio-culturels. Les différents usages et la rentabilité économique issue de la vente des amandes ont été également recherchés. Pour atteindre ces objectifs, la valeur d’usage ethnobotanique des différents organes, le taux de réponse des individus enquêtés et de la marge brute de commercialisation a été recherché. L’inventaire a permis de recenser seulement 26 pieds de I. gabonensis chez 35 paysans. Les travaux ont révélé deux usages principaux chez les Agnis, les Baoulés, les Groussis, les Malinkés et les Morés. Il s’agit de la consommation des amandes connue par 100% des enquêtés et de l’usage thérapeutique de l’écorce connue par seulement 10% de l’échantillon. Les investigations ont montré une marge brute de commercialisation moyenne de 27%. Des travaux complémentaires devront être réalisés pour valoriser d’avantage l’écorce et les feuilles. Aussi, nous préconisons le semis de graines ou le maintien de sauvageons dans les zones dégradées des cacaoyères en vue d’une gestion durable de cette ressource. SUMMARY This work assesses the socio-economic importance of Irvingia gabonensis (Irvingiaceae) or the wild mango tree in the Agnéby-Tiassa region in the south of the Ivory Coast. To this end, a population inventory was carried out in agroforestry areas, in particular in cocoa trees in order to determine the perception of this species by five socio-cultural groups. The different uses and the economic profitability resulting from the sale of almonds were also investigated. To achieve these objectives, the ethnobotanical use value of the different organs, the response rate of the individuals surveyed and the gross marketing margin were researched. The inventory identified only 26 stems of I. gabonensis among 35 farmers. The work revealed two main uses among the Agnis, the Baoulés, the Groussis, the Malinkés and the Morés. This is the consumption of almonds known by 100% of the respondents and the therapeutic use of the bark known by only 10% of the sample. Investigations showed an average gross marketing margin of 27%. Additional work will have to be made out to further enhance the bark and leaves. Also, we recommend the sowing of seeds or the maintenance of wildlings in degraded areas of cocoa trees with a view to sustainable management of this resource.

In this work, comparative study of physicochemical properties and fatty acids of dried arils (DA) oil and those roasted (RA), of Blighia sapida from Côte d’Ivoire have been done using usual methods. The results showed that the crude fat obtained were 59.08± 0.02 g/100 g for dried arils (DA) and 60.51 ± 0.12 g/100 g for roasted arils (RA) respectively. Physicochemical properties of these oils were equal approximately, except level of saponification (241.19 mg KOH/g (DA) against 216.8 mg KOH/g (RA)); acid value (7 mg KOH/g (DA) and 6.28 mg KOH/g (RA)) and ester acid 234.19 mg KOH/g (DA) against 210.65 mg KOH/g (RA) where variances analysis showed that there was significant difference (p<0.05). On the other hand, refractive index, pH, moisture value, relative density and Free fatty acid were respectively; 1.465 (DA) and 1.475 (RA); 5.625 (DA) and 5.8 (RA); 1.757 (DA) and 1.9 (RA); 0.093 (DA) and 0.103 (RA), 3.52 mg KOH/g (DA) and 3.03 mg KOH/g (RA). The color of both oils was yellow. Fatty acid profile of these arils oils revealed that values of DA and RA were equal approximately (variances analysis showed that there was no significant difference (p<0.05)). These arils oils contained high levels of unsaturated fatty acids, 64.10 % (DA) and 65.17 % (RA), especially linolenic acid 20.02 mg/100 g (DA) and 22.18 mg/100 g (RA); linoleic acid 15.37 mg/100 g (DA) and 16.83 mg/100 g (RA) and Oleic acid 12.76 mg/100 g (DA) and 13.21 mg/100 g(RA). The saturated fatty Acids, accounted for 35.90% (DA) and 34.83% (RA) were constituted by palmitic acid with 18.02 mg/100 g (DA) and 18.11(RA) which were higher values. The values of stearic acid were 7.1 mg/100 g (DA) and 7.9 mg/100 g (RA) and 1.85 mg/100 g (AD) and 1.9 mg/100 g (RA) mg/100 g for myristic acid respectively. These results showed that the arils oils of Blighia sapida fruit from Côte d’Ivoire have highly nutritive fat content because rich in essentials fatty acids. These oils may be suitable for soap making and edible (margarine). The oils extracts exhibited good physicochemical properties and could be useful as edible oils and for industrial applications.

Cette étude a été conduite à Zuénoula, dans le but d’évaluer la disponibilité et le niveau de connaissance des plantes sauvages comestibles pouvant servir d’alternatives aux populations locales et contribuer ainsi à leur valorisation. Pour cela, des investigations ethnobotaniques ont été réalisées à l’aide de fiches d’enquête dans 5 localités auprès de 368 individus. Les plantes et les organes comestibles récoltés ont été identifiés au Centre National de Floristique (CNF) d’Abidjan. Ainsi, les 76 espèces récensées appartiennent à 36 familles et 62 genres et représentent 32,34 % des plantes sauvages comestibles recensées en Côte d’Ivoire. Les Fabaceae (33,34 %) et les Malvaceae (22,23 %) sont les familles les plus rencontrées et sont majoritairement sous forme d‘arbres (38,16 %) et d‘herbes (26,32 %). Concernant les parties utilisées, ce sont les feuilles (38,85 %) et les graines (07,45 %) qui sont plus consommées en repas contrairement aux fruits (40,43 %) souvent consommés comme friandise au lieu de cueillette. Les populations (62,23 %) qui ont une bonne connaissance de la flore locale comestible sont aujourd’hui confrontées à la disparition progressive d‘espèces autrefois prisées comme Glyphaea brevis, Irvingia gabonensis et Telfairia occidentalis. Enfin, la consommation de Bixa orellana et de Gymnema sylvestre, espèces très utilisées dans l’alimentation humaine et la médecine en Asie, a pour la première fois été révélée en Côte d‘Ivoire. La poursuite de cette étude par des analyses des valeurs nutritives des espèces les plus sollicitées est vivement souhaitée en vue de leur valorisation au plan nutritionnel.  This study was conducted in Zuénoula with the aim of assessing the local people’s level of knowledge on wild edible plants and the availability of these plants to serve as alternatives for the local population and thus contribute to their development. To achieve this, botanical surveys were carried out in 5 localities involving 368 persons. Plants and edible organs collected were identified at the Centre National de Floristique (CNF) in Abidjan. All 76 species recorded belong to 36 families and 62 genera, and they represent 32.34% of wild edible plants identified in Côte d'Ivoire. Fabaceae (33.34%) and Malvaceae (22.23%) were the most common families and are mainly trees (38.16%) and herbs (26.32%). Concerning the part of the plants used, leaves (38.85%) and seeds (07.45%) were the most consumed in meals, which is contrary to fruits (40.43%) often consumed as sweets at the harvesting sites. The majority of the population (62.23%), which has a good knowledge of the local edible flora, is today confronted with the progressive disparition of species once sought after such as Glyphaea brevis, Irvingia gabonensis, and Telfairia occidentalis. This study reveals for the first time the consumption in Côte d'Ivoire of two plants' species, Bixa orellana and Gymnema sylvestre, widely used in human food and medicine in Asia, highlighting the great diversity of the local flora. Since the nutritional potential of these species has never been studied in Côte d'Ivoire, additional research on the most sought-after species is highly recommended for their nutritional valorization.

Mango seeds are discarded as waste after the extraction of mango juice. This study aims to valorise the kernels oils of mango (Mangifera indica). In this study, the kernel of four mango varieties (Amelie, Brooks, Kent and Keitt) that are grown and processing in north of Cote d’Ivoire investigated were used. The oils of these kernels were extracted by Soxhlet at 80 °C. Their physicochemical properties were determinate using standard methods. Physicochemical properties of the kernels oil were: specific gravity, 0.80±0.08 to 0.93±0.01; refractive index (50 °C), 1.43±0.07 to 1.47 ± 0.10; iodine value, 44.84 ± 0.05 to 59.41 ± 0.03 g I2 /100 g; peroxide value, 0.50 ± 0.00 to 1.90 ± 0.00 meq.O2/kg; acid value, 2.00 ± 0.00 to 7.65 ± 0.01 mg of KOH/g and saponification value, 167.53 ± 0.04 to 188.44 ± 0.04 mg KOH/g. Results revealed that these kernels oil contained a significant presence of oleic (31.14 ± 0.27 to 37.19c ± 0.23) and stearic (20.11 ± 0.12 to 40.43 ± 0.03) fatty acids. All these interesting characteristics confirm their usefulness for different nutritional and industrial applications.

Aims: This study aims to evaluate the physicochemical properties of palm kernel oil extracted from traditional varieties in the Mountain district, West region of Côte d’Ivoire. Study Design: Palm kernels were collected from women crude palm oil producers in three departments of the western part of Cote d'Ivoire. In each department, 50 kg of palm kernel were purchased per supplier. Place and Duration of Study: This study was carried out June to September 2017.The collected almonds of palm kernels were carried out at the Biochemistry and Food Sciences Laboratory of the Félix Houphouët-Boigny University, Abidjan. Methodology: The palm kernel oils were extracted by maceration and their physicochemical properties were determinate using standard methods. Results: The results obtained show that the values for the physicochemical parameters of palm kernel oils from the three departments were similar and fell in those of the standards of Codex Alimentarius 2019. However, physicochemical parameters statistically vary (P<0.05) between the departments. The yields of oils extracted fluctuated between 39.64 ± 2.14 % and 52.26 ± 1.16 %. The refractive index ranges between 1.453 ± 0.01 and 1.454 ± 0.002. The relative density varies between 0.90 and 0.91. The level of insoluble impurities ranged from 0.06 to 0.09 %. The moisture and volatile matter content varied between 0.62 ± 0.05 to 1.94 ± 0.07 %. The acid value and free fat acid percentage varies from 6.37 ± 0.65 to 8.54 ± 0.57 mg KOH/g and 3.20 ± 0.31 to 4.29 ± 0.28 %, the saponification value ranges between 216.02 ± 8.96 mg KOH/g and 248.16 ± 2.40 mgKOH/g, iodine value varies from 17.52 ± 0.43and 19.05 ± 0.95 g of iodine per 100 g of fat and peroxide value range between 6.02 ± 1.13 to 8.38 ± 1.00meq O2 kg of fat. The study of the lipid composition of these fats showed significant presence of fatty acid and unsaponifiable. The major fatty acids are lauric acid (50.50 - 51.00 %), myristic acid (18.35 - 18.80 %) and oleic acid (12.80 - 13.92 %). Conclusion: Given the results, palm kernel oils from the three departments exhibited good physicochemical properties, a clear indication that palm kernel oil could be used as edible and non-edible products in many homes and at various levels of industries in Côte d'Ivoire. There is limited information available about palm kernel oil from the western region of Côte d'Ivoire now and this study systematically researched on it, which can provide useful information for Ivorian oil palm industry.
