The objective of this study is to understand the diversity of edible wild species sold on the markets of Bangui. To do this, ethnobotanical surveys on the marketing of these resources were carried out from September to December 2023 with 150 sellers installed in six popular markets in Bangui. In total, 86 plant species have been recorded distributed in 69 genera and 41 different families. The analysis of the results showed that the Leguminosae family is the richest (8 species); fruits (68.43%) and leaves (22.12%) are the most sold plant organs; edible fruits (45.16%) remain the most predominant category of uses; these species are mainly trees (55.83%) and are more present in forest ecosystems (52.33%). It also appears that these wild food plants were not only consumed for nutritional needs but also for the traditional treatment of 45 pathologies. These results demonstrate that there is still a high diversity of spontaneous food species in the Central African Republic. Given the dual nutritional and therapeutic interest of these resources, and also in the face of socio-economic issues and the change in food culture in urban areas, the promotion of this precious heritage is necessary and essential. Such an approach would be an opportunity both economically and nutritionally for local populations, particularly women. Also, it would be beneficial to deepen research on the phytochemistry of some spontaneous food plants with medicinal properties in order to achieve the manufacture of improved traditional medicines accessible to all.

This study carried out on the methanol extract from the bark of the Manilkara mabokeensis plant, in order to determine the active principle and its effect on the strains of Staphylococus aureus, Shigella sp and Escherichia coli. Two methods of antibiogram (dilution and diffiusion) were used. The methanol of diffusion in solid medium (Mueller Hinton), induced growth inhibition diameter of 20mm, on E. coli and Shigella sp, respectively. However, the S. aureus brain multiplied around the plant extract disc. For the dilution method, the minimum inhibitory concentration was 0.07 for E. coli and 0.09 for Shigella sp. Therefore the extract of the plant was found to be active with a bactericidal effect for E. coli and bacteriostatic effect for Shigella sp. Chemical screening revealed the presence of tannins, flavonoids, the power and quinones. These results confirm the use of this plant to treat some cases of infections observed in the traditional workplace.
