Abstract:

Purpose: To study the involvement of inflammatory pathways in the antidepressant activity of Acacia seyal in mice.Methods: The median lethal dose (LD50) of the extract Acacia seyal (AS) was determined using OECD guideline 425. The antidepressant activity of AS was assessed against BCG (0.2 mg/kg, ip)-induced depression in mice using Tail suspension test (TST) and open field test (OFT) at 4, 24 and 48 hours post BCG administration.Results: The median lethal dose (LD50) for the extract was > 5000 mg/kg orally. The extract AS at all tested doses (250 – 1000 mg/kg) significantly (p ≤ 0.001) decreased the duration of immobility in TST but increased the number of line crossing in OFT post-BCG.Conclusion: The antidepressant activity of the methanol root bark extract of Acacia seyal in mice may involve an inflammatory mechanism. Thus, the extract of Acacia seyal may be suitable for the management of depression in humans resistant to other conventional antidepressant agents. However, further studies are required to ascertain this Keywords: Depression, Acacia seyal, Tail suspension test, Open field test, Bacillus Calmette-Guerin

Abstract:

The objective of this study is to analyze and compare tannins of three common Acacia species of Sudan, since vegetable tannins are important in leather industry. Acacia nilotica and Acacia seyal samples were collected from Sunt Forest in Khartoum State, while Acacia senegal samples were collected from the Debabat Forest in South Kordofan State. Bark samples from bulk collections of the three Acacia species were extracted with boiled deionized water. The amount of tannins present in these bulk samples was determined by Folin-Denis method for total phenolic materials, followed by precipitation with hide-powder. The difference between the amount of phenolic materials present before and after addition of hide-powder represents the amount of tannins present. The percentage of tannins in the leaves, bark, and mature and immature fruits of collections of individuals of Acacia species was estimated; mature and immature fruits of Acacia nilotica contain tannins (22.15% and 22.10%, resp.). The leaves of Acacia nilotica and Acacia seyal contain tannins (11.80% and 6.30%, resp.). The barks of Acacia seyal, Acacia nilotica, and Acacia senegal contain tannins (12.15%, 10.47%, and 3.49%, resp.).

Abstract:

La connaissance du potentiel et de la productivité d'une ressource est une donnée nécessaire à l'élaboration d'une bonne politique de sa gestion. La structure et la productivité des peuplements à Acacia seyal Del. et à Acacia senegal (L) Willd.ont été étudiées dans les formations naturelles de Massenya au Tchad. Sur la base de 32 placeaux de 900 m2, le diameter et la hauteur de tous les individus d’espèces ligneuses ont été mesurés. Pour des espèces adultes à port arbustif, le diameter est mesuré à 50 cm du sol. Les individus juvéniles sont simplement comptés et ranges en classe de hauteur. L’étude de la structure des peuplements et de deux espèces d’Acacia a été réalisée à travers le nombre de tiges à l’hectare et les classes de diamètre. L’Indice de Valeur d’Importance (IVI) a été utilisée pour apprécier la prédominance des espèces sur le site. La productivité des peuplements en gomme a été évaluée en fonction de la production moyenne d’un arbre qui était de 250 g. Les peuplements à Acacia de Massenya sont très denses (619 ± 269 tiges/ha), mais à surface terrière faible (7,10 ± 1,20 m²/ha) due à un grand nombre d’individus de petit diamètre (11,1 ± 2,2 cm). Ce sont des peuplements généralement arbustif (hauteur de 5,2 ± 0,9 m) avec un bon potentiel de juvéniles (408 ± 267 tiges/ha) pouvant se régénérer naturellement. Toutefois, Acacia seyal semble plus apte à coloniser d’autres milieux qu’Acacia senegal. Sur les sept espèces qui prédominent sur le site, Acacia seyal et Acacia senegal réalisent des IVI plus élevés (respectivement 79 et 54). Les espèces à bon potentiel de régénération sont Acacia seyal (65 ± 8 juv./ha), Acacia senegal (58 ± 10 juv./ha) et Guiera senegalensis (51 ± 8 juv./ha). La production annuelle de gomme est estimée à 56 ± 6 kg/ha de gomme friable (à Acacia seyal) et 41 ± 5 kg/ha de gomme dure (à A. senegal).

Abstract:

Considering the improvement of acacia species growth in arid and semi-arid environment, a pot experiment was conducted to evaluate the role of arbuscular mycorrhizal fungi (AMF); Funneliformis mosseae (syn. Glomus mosseae), Rhizophagus intraradices (syn. Glomus intraradices) and Claroideoglomus etunicatum (syn. Glomus etunicatum) on growth and drought tolerance of Acacia seyal Del. seedlings under drought cycles (7, 14, 21 and 28 days). AMF-inoculated seedlings showed a clear colonisation percentage (36–68%). AMF treatment significantly improved seedlings shoot and root growth under all drought cycles compared to non-AMF control seedlings. Moreover, AMF treatment enhanced seedlings drought resistance by increasing root surface area (root length increased by 483.76% and root tips number increased by 1 463.94% under 28 days of drought cycle), there was a strong linear relation between proline accumulation, AMF and drought stress (proline content decreased in treated seedlings by 31.3% and 14.3% and increased by 97.5% and 80.4% in untreated seedlings under drought cycles of 21 and 28 days, respectively). In conclusion, the AMF inoculation improved growth and enhanced drought tolerance of A. seyal seedlings and can be used as a natural biostimulator for acacias seedlings establishment in arid areas.

Abstract:

The aim of this study was to determine the energy properties of fuelwood samples which are preferred and used by local communities. The study used both cross-sectional survey of households and field survey. Systematic household sampling was used for household and random sampling for tree species. The chosen sample sizes for households in the study were 134. The cross-sectional survey of the local community on orderly preference of fuelwood consumption listed Acacia nilotica, Acacia etbaica, Olea africana, Acacia seyal, and Acokanthera schimperi. However, for the laboratory result and detail principal component analysis (PCA) of tree species in their density and moisture, ash, volatile, and fixed carbon contents, Olea africana was strongly recommended for fuelwood preference followed by Acacia nilotica, Acacia etbaica, Acacia seyal, and Acokanthera schimperi. The identification of community preference and scientific assessment on fuelwood consumption on different tree species will enhance the expansion of their plantation program in the region.

Abstract:

The susceptibility of three Acacia species used in Senegal (F. albida Del., A. seyal Del. and A. holosericea A Cunn. Ex G. Don) to M. mayaguensis is studied after inoculation of the nematode at different stages of seedling development (seedling stage, cotyledon and young leaves). The observation of giant cells induced by M. mayaguensis on all three Acacia species testifies to their susceptibility to the nematode. However the pathogenic effect of M. mayaguensis on the growth of A. holosericea and A. seyal is more important than on F. albida. Moreover, the penetration and the development of the nematode is greater with these two Acacia species. The susceptibility of Acacia decreased when nematodes are inoculated on older seedlings. These results indicate that some Acacia sp. used to restore soil fertility will multiply parasites susceptible to infest subsequent crops.

Abstract:

Taking the importance of agricultural production sustainability with limited resources to use efficiency in an arid area, afield experiment was designed to investigate the effect of three, Acacia trees (Acacia nilotica, A. seyal, and A. tortilis) planting combination on soil fertility and Sorghum bicolor L. growth and physiological performance. The sorghum planted in 7 strips between 14 rows of Acacia trees planting combinations and one treeless strip as control. Acacia species plantations significantly increase soil fertility in terms of available nitrogen (N), phosphorus (P), potassium (K) and organic carbon (OC) contents as compared to control, highest level of N and P content (59.01 ± 1.45 and 58.77 ± 1.10 mg/kg) was reported in strip between rows of A. tortilis. Although the highest net photosynthesis rate (P<sub>n</sub>) and stomatal conductance (g<sub>s</sub>) recorded in plants grown between rows of pure A. torilis, and rows of A. torilis–A. seyal, but different Acacia significantly enhanced sorghum growth and physiology with reference to net photosynthesis rate, stomatal conductance and chlorophyll fluorescence (chlF). The results stated linear relation between soil nutrients (N, P, K), P<sub>n</sub>, and chlF increasing soil fertility improve physiological performance of sorghum. In conclusion, the three Acacia improve soil fertility and sorghum growth. Generally, this plantation trial can be environment-friendly alternative agricultural practices in Saudi Arabia or any area with a similar ecological condition to amend the soil and improve crop performance.

Abstract:

Saudi Arabian desert tree Acacia (Vachellia Seyal) used to produce Activated Carbon (AC) by phosphoric acid mediated chemical activation at low temperature. Characterization of AC done based on proximate and detailed analysis including Moisture content, Total Ash content, pH value, Iodine number, Methylene blue number, pore volume and BET surface area. Results revealed that properties of produced activated carbon (PAC) are comparable to commercial activated carbon (CAC). Low ash content and hardness making it suitable for water and wastewater treatment. Cost of production found to be less than $0.5/kg. Both AC used to treat wastewater containing Methylene Blue (MB) dye. Initially the removal efficiency of CAC is higher than the PAC however, both AC reached to similar removal (95.3% for PAC and 98.2% for CAC) within one hour. Growing demand of AC in the country can be meet by producing low cost locally available waste materials Acacia seyal tree branches.

Abstract:

Acacia seyal is one of the multipurpose parkland agroforestry tree species in eastern and southern Africa. It is a common on-farm tree in the Rift Valley of Ethiopia, but information is limited on its effect on soil properties and sorghum growth and yield. The study was conducted to evaluate its effect on selected soil properties and sorghum growth and yield in Guba Lafto district of northern Ethiopia. Six isolated and closely comparable Acacia seyal trees growing on sorghum farms were purposely selected, and plots were marked under the canopy of trees with three radial distances (0–2 m, 2–4 m, and 4–6 m) and one outside of the tree canopy (10 m away from any tree). Soil samples from each distance zone were taken between 0–20 cm and 20–40 cm soil depths for soil property analysis. Four quadrates with 1 m2 at each distance zone in four directions were laid for sorghum growth and yield attribute valuation. The results showed that only total nitrogen (TN) was significantly higher ( P < 0.05 ) at the subsoil layer under the canopy compared to an open area, while other selected soil parameters were not affected by the tree species. Sorghum biomass yield ( P = 0.006 ) and grain yield ( P = 0.025 ) were significantly lower under the canopy of the trees than in the open area. Generally, Acacia seyal had little effect in improving soil properties and showed a negative effect on sorghum yield and growth. Further research on its effect under wide area coverage of parkland system should be performed to bring a radical shift on the intercropping farming system.

Abstract:

Damage caused by elephants was monitored in two woodland stands of Zakouma National Park (Chad) between February and March 1998. The Acacia seyal savanna was more severely damaged (29.8% of trees damaged of which 13.2% severely) than the Combretaceae savanna (26.5% of trees damaged of which only 4.2% severely). Nearly all severely damaged trees showed resprouts (respectively 86.8% and 88.5% in Combretaceae and A. seyal savannas). Both low damage rate and low mortality rate indicate that no serious ‘elephant problem’ occurred in Zakouma National Park. Elephants selected trees to damage according to species and height. Such selection also occurred for severe damage in A. seyal savanna, but only height affected severity of damage in Combretaceae savanna. In both savannas, the plots close to a water point were the most frequently damaged. In Combretaceae savanna, the distribution of damaged trees was clumped. On the other hand, spatial auto-correlation was not significant for the severity or the frequency of damage in A. seyal savanna. Neither tree density nor diversity of woody species affected the spatial patterns of damage or severe damage.

This research is dealing with the analysis of tannins of two common Acacia species of Sudan i.e.Acacia niloticaandAcacia seyal. Bark samples from collections of the two acacia species were extracted with distilled water, 80% methanol and 70% acetone. Two sets of extraction were made, one by boiling, and the other by shaking the samples in the respective solvent for eight hours at room temperature. It was found that the 70% acetone was a more efficient solvent than either water or 80% methanol. In addition, qualitative analysis of the phytochemicals showed that the fruits (garad) contain tannins materials, flavonoids and coumarins.

Abstract:

Aim of the study: Understanding post-fire germination of tree species in arid and semi-arid zones of sub-Saharan Africa.Area of study: Ethiopian Acacia senegal L. and Acacia seyal Del. forests.Material and methods: Seeds were subjected to heat shocks at combinations of four temperatures (60º, 90º, 120º and 150ºC) and three exposure times (1, 5 and 10 minutes). A control was also included, resulting in a total of thirteen treatments. After the application of the heat shocks, the viability of no germinated seeds was assessed after immersion in a Tetrazolium solution. A mixed and a logistic model were used to analyse the influence of heat shock on germination.Main results: Results showed that germination depended on the species, the heat shock treatment and their interaction. Both species showed similar germination results at temperatures below 90ºC in all exposure times, however, germination in Acacia senegal was statistically higher in most of the heat shocks. On the other hand, germination probability decreased in both species, when the exposure time increased, although with a different behaviour. In 1 minute of time of exposure, the germination probability was higher than 60% in the two species throughout the temperature range. However, at 5 minutes of time and temperature smaller than 90°C, the probability of germination was higher than 70% in A. senegal and 50% in A. seyal. Although germination in both species was impacted by the different heat shocks, non-germinated seeds were viable.Research highlights: This paper showed, according to these results, that heat shock would negatively influence the regeneration of both species, and especially for A. seyal.Key words: germination, Acacia, heat shock, logistic model.

Abstract:

Objective: The content and chemical composition of dry distillates of the stem, stem wood and stem bark of Acacia seyal were investigated. The distillates are fumigants of A. seyal locally known in Sudan as Dokhan and widely used for its cosmetic, aromatic and medicinal value for the treatment of candidiasis, genital yeast infection, urinary tract infection, diarrhoea, respiratory tract infection, skin infection and with potent, antioxidant and antimicrobial activities.Methods: The dry distillates were prepared by dry distillation method from the Acacia seyal stem, stem wood and stem bark and investigated chemically by GC-MS analysis.Results: The percentage yield of dry distillates (Dokhan) wer found to be 4.0 %, 4.8%, 1.4.1% v/w for stem, stem wood and stem bark respectively. GC-MS analysis revealed the presence of one hundred and twenty three constituents in the stem distillate with major constituents of solerone (7.27%), furfural (7.15%), catechol (7.11%), syringol (5.56%), allo-inositol (4.86%), mequinol (4.81%), furfuralcohol (3.35%), 3-methyl-1,2-cyclopentanedione (3.24%), phenol (2.73%), homovanillyl alcohol (2.56%) and 3-cresol (2.11%). the wood distillate show detection of eighty compounds, with main compounds: 1, 3-dimethyl-5-methoxypyrazol (10.61%), syringol (6.75%), furfuralcohol (5.24%), mequinol (4.49%), 1,2-anhydro-3,4,5,6-alloinositol (4.26%), 3-methyl-1,2-cyclopentanedione (3.42%), catechol (3.37%), 3-methoxycatechol (3.22%), homovanillyl alcohol (2.78%), homosyringic acid (2.40%), 3-cresol (2.18%), 3-methyl-2-cyclopentenone (2.44%) and 1,2-cyclopentanedione (2.03%). Sixty six compounds were detected in the distillate bark and the main compounds were found to be hexadecanoic (62.83%), catechol (3.38%), tetrapentacontane (3.18%), phenol (2.72%), mequinol (2.30%) and 2-ethylfurane (2.22%).Conclusion: The result concludes that the medicinal Sudanese Dokhan have good potential as sources of different bioactive compounds and antioxidants.

Abstract:

Gum Arabic is a natural gummy exudate gained from the trees of Acacia species (Acacia senegal and Acacia seyal), Family: Fabaceae. Gum Arabic considers as a dietary fiber with a high percentage of carbohydrates and low protein content. Sugars arabinose and ribose were originally discovered and isolated from gum Arabic and it is representing the original source of these sugars. A gum emanation from trees occurs under stress conditions such as heat, poor soil fertility, drought, and injury. Mainly gum is produced in belt region of Africa, mainly Sudan, Chad, and Nigeria. In the food industry, it is used in confectionery; in the pharmaceutical industry, it is used as emulsifier, film coating and others. Traditionally the gum used for chronic renal failure, digestive discomfort, and others. Although gum Arabic considered as an inert substance, recent information demonstrated multiple pharmacological and medical effects, such as weight reduction, antihypertensive, antihyperlipidemic, anticoagulant, antibacterial, antidiabetic, anti-inflammatory, nephroprotective and other effects.

Abstract:

The concept of chance discoveries — serendipity — has been examined with respect to ex situ conservation of ‘reserved’ trees in Tanzania, where selection has little regard to climatic matching. Support for such departure from traditional practice is offered by the introduction, and subsequent growth, of Maesopsis eminii Engl. in the East Usambaras, and by the growth of the dry-savanna Acacia sieberiana DC. var. sieberiana and A. seyal Del. at Lushoto, in a wetter and cooler ecozone.

Abstract:

Water extract of Acacia seyal bark is used traditionally by the population in Djibouti for its anti-infectious activity. The evaluation of in vitro antibacterial, antioxidant activities and cytotoxicity as well as chemical characterization of Acacia seyal bark water and methanolic extracts were presented. The water extract has a toxicity against the MRC-5 cells at 256 μg/mL while the methanolic extract has a weak toxicity at the same concentration. The methanolic extract has a strong antioxidant activity with half maximal inhibitory concentration (IC50) of 150 ± 2.2 μg/mL using 1-diphenyl-2-picrylhydrazyl (DPPH) and IC50 of 27 ± 1.3 μg/mL using 2,2′-azino-bis 3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical methods. For ferric reducing/antioxidant power (FRAP) assay, the result is 45.74 ± 5.96 μg Vitamin C Equivalent (VCE)/g of dry weight (DW). The precipitation of tannins from methanol crude extract decreases the MIC from 64 µg/mL to 32 µg/mL against Staphylococcus aureus and Corynebacterium urealyticum. However, the antioxidant activity is higher before tannins precipitation than after (IC50 = 150 µg/mL for methanolic crude extract and 250 µg/mL after tannins precipitation determined by DPPH method). By matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) analysis, the results showed that the condensed tannins consist of two types of catechin and gallocatechin-based oligomers. The fractionation led to the identification of three pure compounds: two flavanols catechin and epicatechin; one triterpene as lupeol; and a mixture of three steroids and one fatty acid: campesterol, stigmasterol, clionasterol, and oleamide.

Abstract:

This study reported the phytochemical composition of two hydroethanolic extracts of Acacia senegal and Acacia seyal trees from Burkina Faso and their activities, alone or in combination with selected antibiotics, against multidrug resistant bacteria. High performance thin layer chromatography (HPTLC) method was used for phytochemical screening. Total phenolic and total flavonoid ant tannins in leaves extracts contents were assessed by spectrophotometric method. The minimal inhibitory concentrations (MICs) of plant extracts and antibiotics were determined using the microdilution method and p-iodonitrotetrazolium chloride. Combinations of extracts and antibiotics were studied using checkerboard assays. Screening revealed the presence of phenolic compounds, flavonoids, and tannins in the hydroethanolic extract (HE) of the leaves. The HE of A. seyal showed the highest total phenolic (571.30 ± 6.97 mg GAE/g), total flavonoids (140.41 ± 4.01 mg RTE/g), and tannins (24.72 ± 0.14%, condensed; 35.77 ± 0.19%, hydrolysable tannins). However, the HE of A. senegal showed the lowest total phenolic (69.84 ± 3.54 mg GAE/g), total flavonoids (27.32 ± 0.57 mg RTE/g), and tannins (14.60 ± 0.01%, condensed; 3.09 ± 0.02%, hydrolysable). The MICs for HE and antibiotics were in the range of 2–512 and 0.008–1024 mg/L, respectively. All tested HE presented an MIC greater than 512 mg/L except HE of A. senegal. The lowest MIC value (128 mg/L) was obtained with HE of A. senegal against Klebsiella aerogenes EA298 and Escherichia coli AG100A. Interesting restoring effects on chloramphenicol and florphenicol activity were detected with alcoholic extracts of A. senegal against resistant E. coli and K. aerogenes strains that overproduce AcrAB or FloR pumps. The adjuvant effect of HE of A. senegal suggests that the crude extract of leaves could be a potential source of molecules for improving the susceptibility of bacteria to phenicols antibiotics.

Abstract:

The present study is on Acacia seyal gum (ASG), which is an exudate from Talha tree. It provides a rich source of polyphenolics compounds that are used traditionally in folk medicine. The study aims to determine the antioxidant capacity (AC) and functional groups of ASG and Prebio-T-commercial (PTC) samples. The methanol crude extracts of both ASG and PTC have fractioned into chloroform (CHF), hexane (HF), acetone (AF) and methanol (MF) using solvent-solvent portion. Both ferric reducing antioxidant power (FRAP), and cupric reducing antioxidant capacity (CUPRAC) assays for each fraction examined. Crude methanol extracts (CME) and its active compositions also analysed carefully using Fourier Transform Infrared Spectroscopy (FTIR) technique. The findings presented a wide variety of functional groups provided by the FTIR spectra (eights bands approximately. Regarding cupric reducing antioxidant capacity (CUPRAC), the methanol crude extracts values are 888.6�4.57 mg TE/100g extract, for PTC as compared to 474.3� 2.23 mg TE/100g of extract for ASG. However, both methanol and acetone fractions revealed significantly (p = 0.05) high FRAP values ranged between 599.8�7.5 and 741.8�5.8 mg TE/100g fraction; for PTC and ASG, respectively. While CUPRAC showed insignificant (p = 0.05) same values 356.1�2.62 mg TE/100g of fraction; for MF of both PTC and ASG respectively. Therefore, in this study, methanolic fractions (MFs) are found to be more effective than acetone fractions (AFs), except for CHF and HF. Finally, the antioxidant activity of the active fraction has provided some evidence regarding its functional groups which may have used in traditional medicine.

Abstract:

Acacia senegal est une espèce largement répandue dans les zones sèches d¿Afrique. Elle constitue la principale source de production de gomme arabique, un hydrocolloïde utilisé localement ainsi que pour de nombreuses applications industrielles alimentaires ou non. Un inventaire réalisé en 1997 au Burkina Faso a établi une superficie en peuplements naturels de 286 000 ha. Des travaux ultérieurs ont démontré la présence dans ces peuplements d¿espèces apparentées, du sous-genre Aculeiferum (Acacia dudgeoni, Acacia gourmaensis et Acacia laeta). Une actualisation de l¿état des peuplements naturels et artificiels est apparue nécessaire dans le cadre de l¿adaptation de la stratégie de développement de la filière de la gomme arabique. La méthodologie mise en oeuvre a comporté deux phases, la première consistant à identifier les peuplements naturels et artificiels, la seconde à réaliser un inventaire par placettes d¿échantillonnage en vue de caractériser la composition spécifique et la densité des peuplements naturels. L¿étude a abouti à identifier des superficies fort limitées en peuplements naturels et artificiels de A. senegal, ainsi qu¿à constater l¿importance des peuplements naturels de A. laeta et des peuplements mélangés des espèces du sous-genre Aculeiferum. L¿aire naturelle de distribution de A. senegal au Burkina Faso a été précisée et les stations ont été caractérisées. Le potentiel de production de gomme arabique issue de A. senegal s¿établit à environ 25 tonnes/an. En conclusion, l¿accroissement de la production de gomme arabique de A. senegal au Burkina Faso implique l¿établissement de gommeraies artificielles. Un potentiel de production de gommes issues de A. seyal et A. laeta existe. (Résumé d'auteur)

Abstract:

AbstractThe present study is an investigation into beekeeping activity values as land use types practiced in Sudanese forests. The main objectives of the study are to estimate honey yield produced per unit area from four tree species, namely: Acacia seyal, A. nilotica, Ziziphus spina-Christi and Eucalyptus spp. Furthermore, the study aims at estimating its economic value and financial return (US$/hectare) using Return On Investment (ROI) as a decision criterion. In addition, the study aims at identifying the obstacles and constraints which this activity faces. The data were collected through interviews with 96 beekeepers in six selected production areas and a survey of market-related data. A structured questionnaire was used, and a descriptive and comparative analysis carried out. The results indicated that the average annual yield of honey/bee hives is 13 kg, ranging between 10 and 16 kg, and A. seyal showed the highest productivity. Furthermore, the results showed that 15 bee colonies/hectare is more suitable with a return rate of 780 US$/hectare annual income. This result indicates that the productivity of honey yield from forest trees has a considerable economic value and financial return. Thus, these results could be a great incentive to encourage local communities to integrate forest management.
