The high cost of fungicides, the international markets standards for agricultural product quality, the environmental issues and consumer health discourage to the application of chemical control. The strategy is therefore to develop alternative solutions, less expensive and addresses environmental concerns. This study was conducted to evaluate the fungicidal potency of Crotalaria retusa L. on Phytophthora sp. and Fusarium solani, two phytopathogenic fungi. This plant was selected after an ethnobotanical study conducted in the sub-prefecture of Lauzoua in Côte d'Ivoire. It is considered to be the most widely used in the treatment of microbial diseases. The phytochemical screening of this legume species was carried out, and showed the presence of saponosides, sterols, tannins, alkaloids, flavonoids, polyphenols, quinones and polyterpenes. The sensitivity of these two phytopathogenic fungi strains was tested in vitro in presence of the aqueous extract of Crotalaria retusa L. by using double dilution method on PDA medium (Potato Dextrose Agar). The minimum inhibitory concentration (MIC) of spawn growth was 1.56 mg/ml for both fungi. The minimum fungicide concentration (CMF) was 6.25 mg/ml for Phytophthora sp and 12.50 mg/ml for Fusarium solani. The presence of chemical compounds in this plant justifies its antifungal activity and its traditional use areas.

An ethnobotanical survey was conducted to record the various plant families, species, and plant parts used to manage sickle cell disease in the Indenié-Djouablin region eastern Côte d’Ivoire. Nine traditional healers aged 36 to 67 years old were selected in six different villages according to their reputation in knowledge of traditional medicine, their availability and their willingness to share information. A total of 26 species of plants belonging to 20 families were reported to have antisickling activity. Eleven (11) different medication recipes were composed from these 26 species of plants ((Afromonum melegueta (Roscoe) K. Schum., Xylopia aethiopica) mainly). The main plant parts used were stem bark (38%) followed by fruit (18%) and seeds (18%). The majority of the main plants recorded (84.61 %) were wild. From the recorded plants, 65.38 % were trees and 23.07 % shrubs. Most remedies (82%) were made up by decoction and were employed orally (54 %) or by enema (32 %). The potential anti-sickling activity of the plant species recorded during this study could be the effect of alkaloids, polyphenols, quinones and terpenoids compounds found during the phytochemical screening of the 26 plants species.

The ethnobotanical study carried out on the fruits of chilli (Capsicum annuum L.), type "Ahalimancou" in the localities of Aniassué, Affalikro, Sankadiokro and the town of Abengourou located in the east of the Côte d’Ivoire had for main objective to assess the levels of knowledge, the mode of use of this pepper by the local populations, as well as the phytochemical analysis of said chilli. Discussion groups and semi-structured individual interviews were carried out in 4 localities to collect information from 650 inhabitants, including 511 women and 139 men. The results showed that the variables gender, age group, ethnicity and level of education significantly influence (p≤0.05) the levels of knowledge and the mode of use, except the independence between the locality, the level of knowledge and mode of use. In addition, women know more about this type of pepper (80.82%) and use it much more in food (99.41%), as well as in the treatment of diseases (95.69%). People aged 60 and over have higher use levels (81.30%) in therapeutic use. The study also revealed that the Agni ethnic group is distinguished from other ethnic groups (Baoulé, Malinké, Attié) by a greater level of knowledge and use in pathology. Depending on the level of education, it appears that people without education know better (71.63%) and use this type of pepper more in the treatment of pathologies (85.39%). In addition, the study showed that the fresh form remains the only form used. With the exception of quinones, phytochemical analysis revealed that this type of pepper contains several pharmacological components depending on the stages of ripeness. Orange and red fruits had a higher content of alkaloids, polyphenols, flavonoids. The green and yellow fruits were highly rich in sterols and polyterpenes. Catechetical tannins were only present in green fruits. The data from our study could strengthen clinical research on the nutritional and pharmacological properties of this type of “Ahalimancou” chilli.

L'importance de l'hévéa (caoutchouc), Hevea brasiliensis, en tant que culture de rente ne cesse d'augmenter justifiant de s'intéresser à de nouvelles techniques de clonage plus efficaces que le greffage (écussonnage) traditionnellement utilisé pour la production industrielle de matériel de plantation de qualité supérieure. Les bonnes performances sur le terrain (croissance rapide, haut rendement) des hévéas produits par embryogenèse somatique n'ont été constatées jusqu'à présent qu'à l'échelle expérimentale. La propagation de masse in vitro par embryogenèse somatique ou microbouturage de clones d'hévéas sur leurs propres racines reste pénalisée par un manque de réactivité de la plupart des génotypes sélectionnés et par des coûts de production prohibitifs. Face à cette situation, la propagation par bouturage de clones matures sélectionnés issus de micropropagation in vitro a été tentée par la SoGB en Côte d'Ivoire comme une alternative possible à l'utilisation exclusive des techniques in vitro. Les deux clones matures industriels, A (70 ans) et B (53 ans), ont d'abord été rajeunis in vitro par embryogenèse somatique puis micropropagés en plus grand nombre par microbouturage. Après acclimatation, les microboutures enracinées in vitro ont été rempotées dans des pots individuels pour être gérées de manière intensive comme pieds-mères destinés au bouturage. Après 3 semaines en conditions horticoles adéquates, les taux d'enracinement obtenus pour les boutures des clones A et B ont été respectivement de 74,6 % (1203/1613) et 76,5 % (198/259). Les racines adventices néoformées étaient généralement vigoureuses. A l'issue d'une phase d'acclimatation réussie, les boutures se sont développées de façon conforme pour atteindre 4 mois plus tard une hauteur de 25-30 cm suffisante pour être plantées au champ. En sus d'une plus grande vigueur et conformité sur le terrain, les clones issus de bouturage peuvent être produits plus rapidement, sur des surfaces plus réduites à moindre coût et dans des conditions de travail plus faciles par rapport aux plantes issus d'écussonnage. Des analyses en cours devraient permettre d'établir les avantages comparatifs des boutures par rapport aux plants écussonnés en ce qui concerne d'autres caractères à fort impact économique tels que le rendement de latex.

Skin health is a concern for many people. This aim of this study is to evaluate in vitro the antioxidant activity of 10 plants used in cosmetopoeia for the maintenance of skin health. To achieve this objective, 30 extracts were tested using 2,2'-diphenyl-1-picrylhydrazyl radical (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6) acid. -sulfonic) (ABTS + •) assays. The extracts studied were rich in total polyphenols, flavonoids, gallic tannins and alkaloids. For the DPPH reduction, 7 extracts including 5 methanolic and 2 aqueous extracts showed a percentage of inhibition similar to that of Vitamin C (95.79 ± 10.53%) used as a control. With ABTS, 11 extracts (5 methanol, 3 aqueous and 3 hexane) gave reduction percentages close to Trolox (95.97 ± 8.51%). These active plants could play a role in the maintaining of skin.
