This study was aimed at evaluating gastroprotective activity and the acute oral toxicity of the aqueous extract of the stem bark of Cylicodiscus gabunensis. Gastritis was induced with 96% (v/v) ethanol after pre-treatment with different doses of the aqueous extract of C. gabunensis. The gastroprotective effect was determined with the help of macroscopic and microscopic analysis of injured stomachs and the percentages of ulcer inhibition were calculated. Subsequently, using colorimetric methods, a phytochemical screening was carried out on the dry extract of C. gabunensis in order to determine the families of compounds present therein. After the screening, the dry extract was fixed on silica gel and mounted on a chromatographic column in order to isolate the bioactive compounds. Finally, the structures of the isolated compounds were obtained using spectral methods (MS, 1H NMR, 13C NMR, HSQC, and HMBC). The result of this study shows that C. gabunensis does not present any acute toxicity at the doses tested. However, the gastroprotective effect was observed for all doses, with a maximum inhibition of the ulcer at 63.94% at the dose of 400 mg/kg of extract; against 56.73% inhibition for aluminium and magnesium hydroxide at a dose of 50 mg/kg. The phytochemical screening of the crude extract of C. gabunensis showed the presence of several secondary metabolites including sterols, triterpenes and saponins. Five compounds were isolated and characterized by spectroscopic methods as being: \(\beta\)-sitosterol (1), lupeol (2), betulinic acid (3), betulin (4) and 3-O-\(\beta\)-D- sitosterol glucopyranoside (5). LD50 has been found over 5000 mg/kg, indicating that C. gabunensis was not toxic.

“…Cylicodiscus gabunensis (Fabaceae) bark is used in traditional medicine to treat various ailments such as malaria, measles, varicella, bacterial infections, rheumatism, migraine and stomach pain [5]. Cylicodiscus gabunensis (Fabaceae) appears to be an interesting alternative in the management of gastritis at a lower cost.…”

“…Cameroon is a biodiversity hotspot and has some of the most spectacular and finest wildlife species found in Africa (Bobo and Waltert, 2011;WRI, 2012;Sandjong et al, 2013;Ngoule et al, 2015;Tsakem et al, 2015). Parrot species are an integral part of these assets which are part of Africa's biological heritage.…”

“…Next to the plateau are a mountainous area in the west, harbouring portions of the low and highland forests, and the active volcano of Mount Cameroon. Lastly, there is a rolling sub-arid Savannah interspersed with Sahel vegetation (Ngoule et al, 2015) located in the extreme north of the country (Figure 1). The northern zone is drained by the Logone and Chari Rivers, which finally empty into the Lake Chad Basin.…”

ACKNOWLEDGEMENTS Notably, special thanks go to the Ministry of Forestry and Wildlife, Cameroon, for providing a research permit and funds; the Loro Parque Fundación, Spain provided funds. ABSTRACTHumans in every culture exploit wildlife resources around them to satisfy their immediate needs using many different methods. Similarly, parrots are exploited in Cameroon in various ways, for both consumptive and non-consumptive uses, by many cultures there. Trading in parrots is the biggest form of wild bird exploitation, and it is carried out by both the public and the private sectors, to satisfy both local and international demands. This paper therefore examined the challenges and conservation implications of the parrot trade in Cameroon. Focus groups and ground research teams were used for data collection in the national territory. It was evident from the results that the main stakeholders in this trade were the government and the private sector, and the driving force behind the trade were unemployment and poverty. Primary sources of Grey Parrots were the three rainforest regions of Cameroon. The frequency of occurrence of the Grey Parrot in the trade exceeded the numbers of other parrot species traded. The future of the trade in Cameroon is not certain as some of its activities are not in harmony with modern approaches to sustainable wildlife conservation and management. These challenges form the basis of the debate on the consequences and conservation implications of the parrot trade in Cameroon.

Dans le but de connaître les plantes médicinales et leurs usages traditionnels sur l'hypertension artérielle, une étude ethnobotanique a été réalisée dans le département de Divo (région du Centre-Ouest forestier). Les enquêtes ethnobotaniques ont permis de visiter 21 villages et de rencontrer, lors des entretiens semi-structurés, 105 tradithérapeutes, sans distinction d'âge, de sexe et de niveau d'instruction. Cette étude a montré que les populations enquêtées emploient 52 espèces de plantes appartenant à 30 familles botaniques, pour combattre l'hypertension artérielle. Parmi ces familles, les Fabaceae avec 17,31% des plantes prospectées ont été les plus représentées. Ces taxons, dominés par les arbres (50%), appartiennent majoritairement à la fois à la région Guinéo-Congolaise et à la région Soudano-Zambézienne (GC-SZ) avec 36,54% des espèces collectées. Les plantes médicinales identifiées ont servi à la préparation de 154 recettes médicamenteuses dont 151 soit 98,05 % sont monospécifiques. La feuille (33%) a été l'organe végétal le plus utilisé et la décoction (69%) le mode de préparation le plus pratiqué. La voie orale (93%) a été la voie d'administration la plus employée. La caractérisation phytochimique des espèces végétales a révélé la présence des alcaloïdes, des tanins, des flavonoïdes, des saponosides, des stérols et des polyterpènes. Cette étude a permis de montrer que l'hypertension artérielle est connue des tradithérapeutes du département de Divo.
