L’objectif  de  cette  étude  est  d’évaluer au Bénin l’efficacité du réseau des aires protégées dans la conservation des habi- tats favorables et prioritaires de certaines espèces ligneuses d’importance socio-éco- nomique. Il s’agit de Afzelia africana, Anogeissus leiocarpa, Burkea africana, Daniellia oliveri, Detarium microcarpum, Prosopis africana et Khaya senegalensis. Les techniques basées sur le principe d’en- tropie maximale (Maxent) combinées avec les SIG ont été utilisées pour projeter les habitats favorables de ces sept espèces ; le logiciel Zonation a été utilisé pour la modé- lisation des habitats prioritaires. Les points de présence des espèces ont été collectés et associés aux variables bioclimatiques dérivées de la température mensuelle et de la pluviométrie obtenues à partir de la base de données en ligne de AfriClim, ainsi qu’à la variable édaphique (sol). En terme de déterminisme environnemental, les variables bioclimatiques telles que l’écart diurne moyen de la température  (Bio2), les précipitations annuelles moyennes (Bio12), l’évapotranspiration potentielle (ETP) et la variable biophysique sol, sont prédictives pour les distributions des sept espèces. Les habitats protégés plus favo- rables aux sept essences dans la zone gui- néenne commencent aux limites de la forêt classée de Kétou (7°43’N), dans la zone soudano-guinéenne, à partir de la lati- tude de la forêt classée d’Agoua (8°30’N), et dans la zone  soudanienne  à partir  de la latitude de la Pendjari (10°35’N).  Pour  la conservation des habitats prioritaires, l’étude de représentation révèle que, dans les zones soudaniennes (9°75’-12°27’N), guinéenne (6°50’-7°40’N) et soudano-gui- néenne, les aires protégées sont respec- tivement efficaces, peu efficaces et non efficaces.

Benue State is endowed with numerous varieties of useful plants whose fruits, seeds, roots, stems and leaves serve important roles in nutrition but unfortunately many of these plants have not been put to maximum use. The neglect of these forest food plants is attributed to inadequate information on their nutritional potential to serve as food. The broad objective of the study was to examine the nutritional composition of Vitellaria paradoxa fruits, Cissus populnea stem, Afzelia africana seeds, Parkia biglobosa seeds and Prosopis africana seeds. Carbohudrate content was found to be the most abundant nutrient in all the plant species studied when compared with other nutrients. The highest carbohydrate content (58.22±0.2%) was found in Cissus populnea stem followed by carbohydrate content in Afzelia africana seeds (51.36±0.01%). The least carbohydrate content of 35.68±0.06% was found in the fruits of Vitellaria paradoxa. There were significant variations in the concentrations of nutrients screened from the 5 selected plants at p>0.05 level. Proximate analysis showed that Vitellaria paradoxa fruits, Cissus populnea stem, Afzelia africana seeds, Parkia biglobosa seeds and Prosopis africana seeds were good sources of minerals such as Calcium,Magnesium, Potassium, iron and Chlorine. Potassium had the highest concentration in all the plant species when compared with other nutrients. The highest Potassium content (32.92±0.59%) was found in Vitellaria paradoxa fruits followed by Potassium content of 25.15±0.07% in Afzelia africana seeds. However, Potassium content between Prosopis africana seeds (15.77±0.81%) and Cissus populnea stem (15.77±0.61%) were not significantly different. The least concentration of Potassium was found in Parkia biglobosa seeds (8.03±0.11%). The mean quantities of minerals found in the plant species that were screened differ significantly at P<0.05 level. It was concluded that Vitellaria paradoxa fruits, Cissus populnea stem, Afzelia africana seeds, Parkia biglobosa seeds and Prosopis africana seeds were good sources of nutrients and major minerals like calcium, magnesium, potassium, iron and chlorine. Diabetic persons need to be careful about the consumption of these plant species. It was recommended that efforts should be made to conserve and protect these plant species through domestication as they are rich sources of nutrients.

Malus Baccata

Crab apple (Malus baccata (L.) Borkh.) was mainly distributed in Europe as an ornamental plant, but the nutritional properties of its edible fruits were not fully revealed. The aim of the current study was to characterize the phytochemical composition of ripen carb apple fruits and to evaluate their nutritional and antioxidant potentials. The fruits were assayed for moisture and ash content, proteins, lipids, carbohydrates, titratable acidity (TA), pH, total phenolic compounds and natural pigments. Among the analyzed carbohydrates cellulose was found in the highest content (6% dw), followed by sugars (sucrose, glucose and fructose) and 1.8 % dw uronic acids. The total chlorophylls and carotenoids contents in their fruits were 6.51 and 4.80 μg/g fw, respectively. Total monomeric anthocyanins were not detected. The highest content of total phenolic compounds (2.67 mg GAE/g fw) was found in 95 % ethanol extract from fruits, while the total flavonoids were relatively low – 0.1 mg QE/g fw. DPPH assay (17.27 mM TE/g fw) and FRAP assay (14.34 mM TE/g fw) demonstrated in vitro antioxidant activities of crabapple. Malus baccata fruits were evaluated as a rich source of dietary fibers and phenolic compounds with significant antioxidant potential that could be used in human nutrition.

AbstractSample particle size is an important parameter in the solid–liquid extraction system of natural products for obtaining their bioactive compounds. This study evaluates the effect of sample particle size on the phytochemical composition and antioxidant activity of brown macroalgae Sargassum cristaefolium. The crude ethanol extract was extracted from dried powders of S.cristeafolium with various particle sizes (> 4000 µm, > 250 µm, > 125 µm, > 45 µm, and < 45 µm). The ethanolic extracts of S.cristaefolium were analysed for Total Phenolic Content (TPC), Total Flavonoid Content (TFC), phenolic compound concentration and antioxidant activities. The extract yield and phytochemical composition were more abundant in smaller particle sizes. Furthermore, the TPC (14.19 ± 2.08 mg GAE/g extract to 43.27 ± 2.56 mg GAE/g extract) and TFC (9.6 ± 1.8 mg QE/g extract to 70.27 ± 3.59 mg QE/g extract) values also significantly increased as particle sizes decreased. In addition, phenolic compounds epicatechin (EC), epicatechin gallate (ECG), epigallocatechin (EGC), and Epigallocatechin gallate (EGCG) concentration were frequently increased in samples of smaller particle sizes based on two-way ANOVA and Tukey’s multiple comparison analysis. These results correlate with the significantly stronger antioxidant activity in samples with smaller particle sizes. The smallest particle size (< 45 µm) demonstrated the strongest antioxidant activity based on DPPH, ABTS, hydroxyl assay and FRAP. In addition, ramp function graph evaluates the desired particle size for maximum phytochemical composition and antioxidant activity is 44 µm. In conclusion, current results show the importance of particle size reduction of macroalgae samples to increase the effectivity of its biological activity.
