“…Le groupe cible est constitué de ménages de plusieurs groupes socioprofessionnels à savoir les agriculteurs, les chasseurs, les récolteurs de Produits Forestiers Non Ligneux (PFNL), les éleveurs et les exploitants forestiers conformément aux travaux de Adjakpa et al (2016) dans le milieu d'étude. Pour définir la taille de l'échantillon par village, un taux de sondage de 15 % (Adjakpa et al, 2016) a été appliqué à l'effectif total des ménages de chaque village (INSAE, 2013) et l'effectif obtenu a été reparti de façon quasi-équitable au sein des groupes socioprofessionnels. Au total, 492 ménages ont été enquêtés.…”

In Africa, since several decades a rarefaction of many plant species because of their daily use by people can be observed. This study which was conducted in the subwatershed of the Kossi River aims to collect peasant perceptions about the state of phytodiversity. The data were collected through an individual survey in 10 villages with 492 households. The software CAP version 2.15. and R version 3.3.3. were used for the statistical analysis. In total, 94 species belonging to 83 genera and 38 families were identified. The dominant genera are Ficus, Ocimum, Acacia and Blighia. Forty-six (46) species of the listed species (48.94%) are currently rare and 9 species (19.57%) of those rare species are threatened in Benin. Value of importance (IV) of activity and the consensus value (UCs) of the choice of activity show that logging, agriculture and breeding have greatest influence on species loss. This study gives information on the most used species by the populations and those we can select for reforestation campaigns. As a perspective, a work on the temporal dynamics of the land use units of this sub-basin will be done to better appreciate their evolution over time. En Afrique, on assiste depuis plusieurs décennies à la raréfaction de plusieurs espèces végétales du fait de leur utilisation quotidienne par les populations. La présente étude conduite dans le sous-bassin versant de la rivière Kossi vise à recueillir les perceptions des populations locales sur l’état de la phytodiversité. Les données ont été collectées à travers une enquête individuelle dans 10 villages auprès de 492 ménages. Les logiciels CAP version 2.15. et R version 3.3.3. ont été utilisés pour les analyses statistiques. Au total, 94 espèces reparties en 83 genres et 38 familles ont été recensées. Les genres dominants sont Ficus, Ocimum, Acacia et Blighia et les familles les mieux représentées sont les Caesalpiniaceae, les Papilionaceae et les Combretaceae. Quarante-six des espèces recensées (48,94%) sont actuellement rares et 9 de ces espèces rares (19,57%) sont menacées au Bénin. La Valeur d’Importance (IV) de l’activité et la valeur consensuelle (UCs) du choix de l’activité ont révélé que l’exploitation forestière, l’agriculture et la transhumance sont les principaux facteurs responsables de cette raréfaction. Cette étude renseigne sur les espèces les plus utiles pour les populations et celles à apporter en cas d’enrichissement. Comme perspective, la dynamique temporelle des unités d’occupation du sol de ce sous-bassin sera abordée pour mieux apprécier leur évolution dans le temps.

“…Regarding food uses, the fruit of A. senegalensis has a sweet taste and is highly appreciated. The flowers and the seeds with aromatic flavor are used by indigenous population to season food [19]. A. senegalensis is also of major commercial importance, contributing significantly to household income [20][21][22].…”

Background The growing interest for more natural products in food and health industries has led to increasing research on traditional knowledge related to plants. While theoretical knowledge (TK) on the uses of a species informs on the wide spectrum of potential uses of that species, actual uses (AU) highlight their potential being actually used. Distinguishing between the two is important when reporting ethnobotanical studies. However, studies often equated AU and TK, sometimes misleading conclusions, and decision-making. This study assessed TK, AU, and difference between TK and AU of Annona senegalensis and how each is related to factors such as age, sex, sociolinguistic group, and main activity in Benin republic. Methods Data were collected through semi-structured individual interviews (n = 755) and analyzed using among others, relative frequency of citation (RFC), and use-value (UV). Results A total of 168 theoretical uses were recorded but only 92 were “actually” practiced, of which four were food and 88 medicinal uses. TK and AU were positively correlated. As expected, TK was also significantly higher than AU, indicating that some potential uses of the species are still not valued. Sociolinguistic group and main activity, not age and sex, were the main factors influencing TK, AU, and difference between TK and AU. The highest TK was found with Bariba sociolinguistic group and the highest AU with Otamari. Fruits (100%) and flowers (10%) were the most used organs for food, while leaves (40%) and roots (7%) were mostly used for medicinal purposes. The most common food uses were consumption of the ripe fruits (100%), and food seasoning with flowers (10%). The most cited diseases were malaria (28%) and intestinal worms (8%). Conclusions The study illustrated the importance of differentiating between TK and AU. It documented the wide range of the uses of A. senegalensis, while highlighting its most common uses, and the need to better valorize and sustainably manage the species.

“…The wild African custard-apple, Annona senegalensis (Magnoliales: Annonaceae) is commonly found in savannas throughout tropical Africa. Also known as soursop, dorgot (Wolof) and sunkungo (Mandinka), a decoction of its leaves and roots is used by rural African communities as a TM for the treatment of seizures, suggesting that the preparation has anticonvulsant and/or sedative properties (18). Studies have shown that extractions from root or stem have mild anticonvulsant properties on chemically induced seizures in rodents, supporting a possible role of this TM in the treatment of epilepsy (19)(20)(21)(22)(23)(24).…”

Drosophila parabss Flies as a Screening Model for Traditional Medicine: Anticonvulsant Effects of Annona senegalensis

et al. 2021

Epilepsy is among the most common serious neurological disorders and affects around 50 million people worldwide, 80% of which live in developing countries. Despite the introduction of several new Anti-Epileptic Drugs (AEDs) in the last two decades, one third of treated patients have seizures refractory to pharmacotherapy. This highlights the need to develop new treatments with drugs targeting alternative seizure-induction mechanisms. Traditional medicine (TM) is used for the treatment of epilepsy in many developing countries and could constitute an affordable and accessible alternative to AEDs, but a lack of pre-clinical and clinical testing has so far prevented its wider acceptance worldwide. In this study we used Drosophila melanogaster paralyticbangsensitive(parabss) mutants as a model for epileptic seizure screening and tested, for the first time, the anti-seizure effect of a non-commercial AED. We evaluated the effect of the African custard-apple, Annona senegalensis, which is commonly used as a TM for the treatment of epilepsy in rural Africa, and compared it with the classical AED phenytoin. Our results showed that a stem bark extract from A. senegalensis was significantly more effective than a leaf extract and similar to phenytoin in the prevention and control of seizure-like behavior. These results support that Drosophila constitutes a robust animal model for the screening of TM with potential value for the treatment of intractable epilepsy.
