Abstract:

Ethnopharmacological relevance: Bombax costatum Pellegr. et Vuillet. (Bombacaceaea) is a plant used in traditional medicine in Cameroon to treat memory impairment, anxiety, insomnia and agitation. Aim of the study: The aqueous extract of Bombax costatum is evaluated for its anxiolytic like effect in mice using experimental models. Materials and methods: The plant extract is administered orally to mice. They were tested one hour later in the stress-induced hyperthermia, hole board, and open field or elevated plus maze tests, respectively. Finally, the brain Gamma aminobutyric acid [GABA] content and GABA-T were quantified in Bombax costatum aqueous extract-treated mice at the end of elevated plus maze test. Results: Bombax costatum aqueous extract showed anxiolytic activity. In stress-induced hyperthermia test, the plant extract significantly antagonised the increase of temperature. There is a significant reduction in the stress-induced hyperthermia from 1.13 ± 0.06℃ in the negative control group treated with distilled water to 0.26 ± 0.02℃ in the group of mice administered 100 mg/kg aqueous extract. In addition, Bombax costatum showed antipyretic activity by reducing the body temperature. In the elevated plus maze test, the aqueous extract increased the number of entries into, percentage of entries into, and percentage of time in open arms. It also reduced the percentage of entries and time in closed arms. Conclusion: The obtained results suggested that Bombax costatum aqueous extracts possess anxiolytic-like and antipyretic activities in mice. This plant could be helpful in the treatment of anxiety and fever in traditional medicine in Cameroon.

Abstract:

Arbre des savanes et des forêts claires sahélo-soudaniennes à guinéennes, Bombax costatum est une espèce fortement exploitée pour ses calices et menacée dans plusieurs localités au Burkina Faso. Une alternative à la conservation résiderait dans la reconnaissance de l'intérêt économique de l'espèce. Cette étude évalue la valeur monétaire de la productivité en calices de B. costatum pour fournir des arguments nécessaires à sa conservation. Pour ce faire, des individus de B. costatum ont été échantillonnés dans trois modes d'utilisation des terres ; leur production florale a été intégralement récoltée afin d'évaluer la quantité de calices produite. Des modèles allométriques ont été élaborés pour prédire la productivité en calices. La valeur monétaire des calices par pied de B. costatum a été estimée à partir de la valeur d'échange des calices secs sur les marchés en trois périodes de l'année. Les résultats montrent que la productivité en calices n'est pas significativement influencée par le mode d'utilisation des terres. Parmi les modèles allométriques ajustés, le modèle linéaire de la forme vY = a + bX prédit le mieux la productivité en calices de B. costatum. La valeur monétaire des calices évaluée par pied varie suivant le diamètre et la période. Pour une même période, elle est de 2,57 $US pour les diamètres compris entre 10 et 25 cm et 26,10 $US pour les diamètres supérieurs ou égaux à 50 cm. Sachant que la valeur monétaire des calices ne représente qu'une partie de la valeur monétaire totale de B. costatum, il importe de sensibiliser les populations locales à la plantation de l'espèce et à des techniques de récolte peu préjudiciables.

Abstract:

Bombax costatum (faux kapokier) est une espèce des zones soudaniennes peu étudiée et sous-utilisée. Cette étude a évalué les connaissances sur les usages de B. costatum en relation avec les facteurs socio-démographiques (âge et sexe) et le groupe socioculturel. À cet effet, 118 entretiens individuels semi-structurés ont été réalisés dans les terroirs riverains de la réserve de biosphère de la Pendjari au Bénin. La fréquence relative de citation, la valeur d’usage rapportée et l’indice d’importance culturelle ont été utilisés pour quantifier les usages et l’importance de l’espèce. Au total, 46 usages ont été recensés et classés en huit catégories d’usages dont les plus citées et ayant les valeurs d’importance culturelle les plus élevées sont les usages alimentaires et médicinaux. Le calice est la partie de plante la plus sollicitée pour les usages alimentaires ; il est de surcroît localement commercialisé. Les usages médicinaux impliquent plusieurs organes/parties (calice, feuille, écorce, graine et racine). Les connaissances sur les usages de B. costatum variaient significativement entre groupes socioculturels mais pas entre sexe et catégorie d’âges. En effet, les groupes socioculturels Berbas et Gourmantchés, contrairement aux Waamas, Natimbas et Peulhs, possédaient plus de connaissances sur les usages de B. costatum et avaient une préférence pour les usages alimentaires. La promotion des usages alimentaires de B. costatum peut être envisagée et ainsi servir de point de départ pour sa plus large valorisation. Les études futures devraient toutefois explorer d’autres régions d’occurrence de l’espèce et mettre l’accent sur la valeur nutritionnelle, les revenus générés par la plante, de même que sa propagation en vue de sa valorisation.

Abstract:

Bombax costatum est une espèce agroforestière menacée de disparition du fait des fortes pressions anthropiques qu’elle subit par le prélèvement de son calice. La présente étude a pour objectif d’évaluer l’influence des modes d’affectation des terres sur les caractéristiques dendrométriques, les types morphologiques et la phénologie de B. costatum dans la Réserve de biosphère de la Pendjari (RBP). Quatorze placeaux de 200 m × 200 m répartis dans quatre modes d’affectation des terres (zone d’occupation contrôlée, chaîne de l’Atacora, zone cynégétique de la Pendjari et Parc national de la Pendjari) de la RBP ont été inventoriés. Les données telles que le diamètre à hauteur de poitrine, la hauteur totale, le nombre d’individus, l’aspect de l’écorce et la couleur des fleurs ont été collectées. Les caractéristiques structurales de B. costatum ont été évaluées à trois niveaux : les paramètres dendrométriques dont la densité, le diamètre moyen, la surface terrière et la hauteur moyenne ; les structures en diamètre ; la distribution de fréquence des différents types morphologiques obtenus (aspect de l’écorce, couleur de la fleur). Pour tester les différences entre les modes d’affectation des terres, une ANOVA, une analyse log-linéaire et une analyse de covariance ont été effectuées respectivement sur les paramètres dendrométriques et les types morphologiques suivant les modes d’affectation des terres. Le mode d’affectation des terres a un effet significatif (P < 0,05) sur la densité des individus adultes, le diamètre moyen, la hauteur moyenne, les types morphologiques et la phénologie de B. costatum. La densité des individus adultes est plus élevée dans les zones d’occupation contrôlée et la chaîne de l’Atacora. Il ressort des résultats que l’espèce a encore un potentiel semencier qui assure sa pérennisation mais qu’une utilisation contrôlée est nécessaire pour sa conservation durable.

Abstract:

Effect of temperature on seed germination of Bombax costatum Pellegr & Vuill. (Malvales: Malvaceae), from four provenances in South Western Nigeria was investigated. A set of three replicates of 25 seeds per provenance were used for the experiment which was laid in a completely randomized block design. The seeds were exposed to fire temperature regimes for germination tests: 28 oC, 20 oC, 5 oC, 35 oC and 20 oC. Seed germination was recorded for 4 weeks. Data obtained were subjected to analysis of variance. Result showed that significant differences in seed germination under varying temperature regimes (P < 0.05). Interaction effect between temperature and provenances was not significant (P < 0.05). Seeds placed in ambient temperature had the highest mean number of germination (20.75) while the least mean value (0.17) was observed for cold room (-20 oC). B. costatum seeds should be exposed to ambient temperature so as to promote seed germination.

Abstract:

Les facteurs climatiques et anthropiques sont à l’origine de la régression de la population de nombreuses espèces ligneuses en zone soudanienne. Anogeissus leiocarpa, Bombax costatum et Detarium microcarpum sont des espèces qui ont une importance socio-économique avérée et donc elles se révèlent être vulnérables. L’évaluation comparée de l’état des peuplements des trois espèces dans les aires protégées et non protégées suivant le gradient climatique permettra de disposer d’informations utiles pour leur gestion durable. La structure des populations a été évaluée à partir d’inventaires forestiers basés sur un échantillonnage aléatoire à travers des parcelles rectangulaires de 1000 m². Les individus dont le diamètre du tronc à 1,3 m de hauteur est supérieur ou égal à 5 cm ont été mesurés. La régénération (individus à D1,3 m < 5 cm) a été comptée par classe de hauteur dans des sous-placettes de 25 m². Les densités et les surfaces terrières des trois espèces varient significativement suivant le gradient de protection dans chaque secteur climatique. A. leiocarpa et D. microcarpum possèdent de bonnes structures démographiques dans les deux secteurs climatiques soudaniens, indépendamment du type d’utilisation de terres. Seule la densité de B. costatum montre une différence significative le long du gradient climatique entre les aires protégées. L’étude révèle l’importance des aires protégées dans la conservation de ces espèces vulnérables.Mots clés : Burkina Faso, zone soudanienne, aires protégées, aires non protégées, espèces vulnérables, conservation. Climate and land use types are mainly responsible for the decline of many woody species in Sudanian areas. Anogeissus leiocarpa, Bombax costatum and Detarium microcarpum are high-value but vulnerable species due to the anthropogenic pressure. The compared assessment of the state of the targeted species in the protected and unprotected areas along the climatic gradient will provide information that could help implementing sustainable management of these species. The population structures were evaluated from forest inventories based on a random sampling through rectangular plots of 1000 m². The adult individuals of each species with diameters ≥ 5 cm at 1.30 m of heigh were measured. The juvenile individual with diameters that were less than 5 cm were counted and classified into height classes within plots size of 25 m². The structural characteristic of the targeted species vary significantly between land uses within each climatic zone. A. leiocarpa and D. microcarpum showed a stable population structure between the two climatic sectors, irrespective of management regimes. Only density of B. costatum shows a significant difference in the PAs and along climatic gradient. The study reveals the importance of protected areas for these vulnerable species conservations.Keywords: Burkina Faso, Sudanian zone, protected areas, unprotected areas, vulnerable species, conservation.

Abstract:

Effect of storage and concentration of potassium carbonate (K2CO3) on the viscosity and related physico – chemical properties of genger (Bombax costatum) powder was determined. Genger powder was stored for a period of four (4) months (May-August) at 30oc ± 5oc under varying concentrations of K2CO3: 0%, 5%, 10% and 15% in two containers (plastic, giving samples A – D and metal tins, giving samples A1 – D1). Thereafter, the moisture and crude fat contents, water absorption capacity, least gelation concentration, effect of K2CO3 concentration on gel strength and viscosity of the stored powders were determined, using standard methods of analysis, with fresh powder (analyzed before storage) as control. Moisture content decreased significantly (p < 0.05) from 8.37% to 3.04% and 2.00% in samples D and D1 respectively, while crude fat content increased significantly (p < 0.05) from 2.50% to 7.50% and 10.05% in the same samples. Water absorption capacity also increased significantly (p < 0.05) from 6.4g/g to 6.40g/g in the fresh sample to 7.30g/g and 8.30g/g in samples D and D1 respectively. Gelation capacity increased considerably, with 15% K2CO3 giving very strong gels at 1.50% concentration. The overall viscosity increased significantly (p < 0.05) with increase in concentration of (K2CO3) from 64.00FN to 110.00FN after storage. Generally, samples stored in metal tin gave better results than those in the plastic container.

Abstract:

Wild Edible Plants are common in the diet of rural communities of sub-Saharan Africa. In Guinea-Bissau, West Africa, wild plant resources are widely used in human diet, but very few studies have addressed them. The aim of this study is to reveal: (1) the wild and semi-cultivated leafy vegetables consumed in Guinea-Bissau; and (2) the nutritional composition of those plants traded at the largest country market in Bissau. Our results revealed that 24 native or naturalized species with edible leaves are currently consumed by Guinea-Bissau population. Five of them were found at the market: dried leaves of Adansonia digitata, Bombax costatum and Sesamum radiatum, and fresh leaves and shoots of Amaranthus hybridus and Hibiscus sabdariffa. The analysis of the nutritional properties revealed that leaves contain a significant amount of protein (10.1–21.0 g/100 g, dry basis), high values of macronutrients and micronutrients, as well as of phenolic compounds (13.1–40.3 mg GAE/g) and a considerable antioxidant capacity (DPPH 111.5–681.9 mg Eq Trolox). Although price and availability vary among the leafy vegetables analyzed, these traditional foods appear to be a good dietary component that can contribute to food security in Guinea-Bissau and in other West African countries, as these species are widely distributed in this region.

Abstract:

Structural composition based on diameter and height class distribution of the tree species of Dudhpukuria-Dhopachori Wildlife Sanctuary, Chittagong, Bangladesh was assessed. A total of 183 tree species having ≥ 10 DBH belonging to 125 genera and 48 families was recorded from the study area. Different species were found to dominate in different DBH classes, i.e. Aporosa wallichii (4.06%), Artocarpus chama (1.54%) and Dillenia pentagyna (0.38%) dominated 10 - < 25 cm, 25 - < 40 cm and 40 - < 55 cm DBH, respectively. Swintonia floribunda was found in maximum (7 out of 8) number of DBH classes. Both the percentage of tree individuals (73.18%) and number of species (169) were highest in 10-24.5cm DBH range. Similarly, Dipterocarpus turbinatus (14.5-24.4m and 24.5-34.4m) and Swintonia floribunda (34.5-44.4m and 44.5-54.4m) were dominant in two height ranges each. On the other hand, height range 4.5 - 14.4 m was dominated by Aporosa wallichii (4.36%). Dipterocarpus costatus, Artocarpus chama, Syzygium firmum and Bombax insigne were found in all the height classes. Both the number of tree species and number of individual stems (167 species; 1,684 individuals) were highest in the height range of 4.5-14.4m. The number of species and tree individuals decreased linearly with increasing height. All these indicate that, there was a sustainable natural regeneration and successful recruitment of Aporosa wallichii, Dipterocarpus turbinatus, Lithocarpus acuminata, Grewia nervosa and Artocarpus chama in Dudhpukuria-Dhopachori Wildlife Sanctuary. Dipterocarpus turbinatus was found as dominant species as it constitures maximum (5.56%) percentage of all tree individuals. The findings of the study may be useful for protection, conservation and sustainable management of Dudhpukuria-Dhopachori Wildlife Sanctuary.J. Biodivers. Conserv. Bioresour.

Abstract:

The sustainable conservation of forest resources in a context of climate change and population growth would be compromised in their current form of exploitation by rural communities. The objective of this study is to assess the impact of climate change on the dynamics of habitats favorable to species of conservation priority in the forests under ONAB management as these species are heavily used by the populations living along the shores of these forests. The study will consist of: Khaya senegalensis, Afzelia africana, Khaya grandifoliola, Pterocarpus erinaceus, Anogeissus leiocarpa, Milicia excelsa, Albizia zygia, Vitex doniana, Antidesma laciniatum and Bombax costatum. Techniques based on the principle of maximum entropy (Maxent) combined with GIS were used to project the favorable habitats of these ten species under current and future climatic conditions (Horizon 2050). Species occurrence data were collected and combined with bioclimatic data derived from the Worldclim database and the edaphic (soil) variable. Two climate models were used for future projections (CNRM-CM5, HadGEM-ES models) under the IPCC A2 scenario, and the partial ROC approach was used for the evaluation of the predictions of ecological niche models. Variables such as cec2 (cation exchange capacity, horizon 5-15cm), bio17 (precipitation of the driest quarter), bio12 (annual precipitation), bio3 (isothermality), bio6 (minimum temperature of the coldest month) and bio7 (annual thermal amplitude) were found to be the most relevant respectively for the distribution of Khaya grandifoliola, Albizia zygia, Anogeissus leiocarpa, Antidesma laciniatum, Afzelia africana and Khaya senegalensis. Under current conditions, only 7% of the Beninese territory would be very favorable to the conservation of Khaya senegalensis and the CNRM-CM5 model predicts an increase of 27.5% and 13.2% respectively of these very favorable and moderately favorable areas by 2050 through conversion of unfavorable areas (7.4%). On the other hand, this model predicts an opposite trend at the level of Afzelia africana where it predicts a decrease of 8.1% and 1.8% respectively of the very favorable and moderately favorable areas and an increase of 5.1% of the unfavorable areas. Ecological niche modeling has basically revealed the conversion of some currently unfavorable habitats into very favorable habitats for conservation (this is the case of Khaya grandifoliola, Khaya senegalensis and Vitex doniana) and the extension of some habitats unfavorable to conservation (Anogeissus leiocarpa, Bombax costatum, and Pterocarpus erinaceus) by 2050. This study provides scientific support for planning and is a decision support tool for the conservation of these species at the socio-economic level.

Abstract:

Background In Africa, the Detarium microcarpum Guill. & Perr. species is extremely important culturally, ecologically and socio-economically. This importance has led to its over-exploitation leading to an in situ rarity of its individuals. As a consequence, a conservation alert is increasingly reported across the continent due to the risk of extinction of this multipurpose plant. Unfortunately, indicators of regeneration and conservation guidelines for this species have been not developped yet. The objective was to evaluate the habitat, population distribution, dendrometric characteristics and structure of the plant which are indicators of regeneration in Cameroon. Methodology A floristic inventory as well as the vegetation transect method was used in the villages Def, Karna Manga and Karna Petel located in Adamawa, Cameroon. Results A total of 109 individuals of the plant were counted with a density of 3.5 individuals per hectare. No plant individuals regenerated in human-controlled habitats (bush fields and home gardens). Population distribution, companion species (Bombax costatum, Piliostigma thonningii and Terminalia macroptera) more recurrent, species of the family Caesalpiniaceae in majority, dendrometric characteristics with a significant difference (P ˂ 0.05) between sites, horizontal and vertical structures although all significant at Karna Manga, showed site-specific patterns. Conclusion The regeneration indicators (habitat, population distribution, structure and dendrometric characteristics: crown diameter, diameter at breast height, height of the first large living branch and tree height) showed that conservation in situ requires accounting for local, site-specific conditions. For the continuation, the less expensive domestication techniques specific to the plant are recommended.
