Résumé :

The flow characteristics of three varieties of Canarium schweinfurthii Engler nuts (Canarium schweinfurthii short, Canarium schweinfurthii long and Canarium schweinfurthii large – CSHT<sub>LRG</sub>) relevant for the design and development of handling and storage systems was studied at three different moisture levels (10.20, 17.23 and 25.06% wet basis). The flow characteristics investigated include the normal stress, the shear stress, the initial shear stress, the coefficient and angle of the internal friction, the coefficient of mobility and the size of the discharge opening. An Instron universal machine at a cross-head speed of 25 mm·min<sup>–1</sup> was used to obtain the shear force. The results obtained showed that all the flow properties increased with an increase in the moisture content except for the coefficient of mobility. Moreover, the variety of the C. schweinfurthii nuts had a significant effect (P < 0.05) on the flow characteristics. CSHT<sub>LRG</sub> had the best ability to flow freely than the other varieties. The hopper side wall angle for all the varieties ranged from 67–70°. Round, square and triangle shapes are all acceptable for the smooth flow of C. schweinfurthii nuts.

Résumé :

The Burseraceae is an important family of resin-producing trees and shrubs, which have yielded biologically active essential oils. Boswellia dalzielii and Canarium schweinfurthii are members of the family that are used in West African traditional medicine for a variety of ailments. The leaf essential oils of B. dalzielii have been obtained from 2 different locations in north-central Nigeria, while the leaf and stem bark essential oils of C. schweinfurthii have been obtained from 3 locations. The chemical compositions of the essential oils have been determined by gas chromatography-mass spectrometry and show wide variation, especially for the leaf essential oils. The leaf essential oils of B. dalzielii and C. schweinfurthii have been screened for antibacterial and antifungal activity; C. schweinfurthii leaf essential oil showed remarkable activity against Aspergillus niger with a minimum inhibitory concentration of 78.1 μg/mL.

Résumé :

The reciprocal crosses between two citrus cultivars and Citropsis schweinfurthii (Engl.) Swing. & M. Kell. were conducted. The cross between `Nanpu' tangor {`Kiyomi' tangor (Citrus unshiu Marc. × C. sinensis Osbeck) × `Fairchild' tangerine-tangelo [clementine (C. clementina hort. ex Tanaka) × `Orlando' tangelo (C. paradisi Macf. × C. reticulata Blanco)]} and C. schweinfurthii produced some developed seeds with an average weight approximately 1/10 of that of the seeds obtained from open pollination in `Nanpu' tangor. These seeds germinated on Murashige and Tucker medium, and three and 28 seedlings were obtained from crosses using C. schweinfurthii as the female and the male parent, respectively. The absolute nuclear genome size of these seedlings [∼0.84 pg of DNA content per somatic nucleus (2C)] was intermediate of that of the `Nanpu' tangor (0.78 pg/2C) and C. schweinfurthii (0.90 pg/2C) seedlings. The chromosome counts of the young leaves revealed that they were diploids (2n = 2X = 18). Furthermore, the hybridity of the seedlings obtained from the reciprocal crosses between `Nanpu' tangor and C. schweinfurthii was confirmed by randomly amplified polymorphic DNA (RAPD) analysis and cleaved amplified polymorphic sequence (CAPS) analysis. These hybrids will be utilized as important materials for investigating the phylogenic relationships between these genera in the subfamily Aurantioideae.

Résumé :

Lannea schweinfurthii is a valuable medicinal plant species among different ethnic groups in tropical Africa. The aim of the current study was to review existing literature on the ethnomedicinal uses, phytochemistry and pharmacological properties of L. schweinfurthii in an effort to evaluate the therapeutic potential of the species. The relevant information on the ethnomedicinal uses, phytochemistry and pharmacological properties of L. schweinfurthii was generated from several sources including books, book chapters, theses, scientific reports and journal articles obtained from the library and internet sources such as SciFinder, Wiley, Web of Science, American Chemical Society publications, PubMed, BMC, Elsevier, Science Direct, Scielo and Scopus. Traditionally, L. schweinfurthii is used against reproductive system disorders, respiratory disorders, injuries, headache, blood system disorders, infections or infestations and gastro-intestinal disorders. The phytochemical compounds that have been isolated from L. schweinfurthii include alkaloids, anthocyanins, flavonoids, glycosides, phenols, saponins, steroids, tannins and terpenoids. The in vitro and animal studies carried out so far from the crude extracts and compounds isolated from the species exhibited acetylcholinesterase inhibitory, anti-apoptotic, antibacterial, antiviral, anti-giardial, anti-inflammatory, antioxidant, antiplasmodial, antitrypanosomal, hepatoprotective, larvicidal and cytotoxicity activities. Detailed ethnopharmacological studies emphasizing clinical and toxicological evaluations are needed to assess efficacy and safety of the species as herbal medicine.

Résumé :

Introduction and objective: Sickle cell disease is an inherited pathology to an abnormality of hemoglobin precisely hemoglobin S for which there is no curative therapy. It mainly affects sub-Saharan African and Caribbean populations. Thus, this study aims to make the phytochemical screening of Cremaspora triflora and Macaranga schweinfurthii as well as to evaluate the antisickling activity of their purified alkaloids. Methodology: Chemical screening was performed using color and precipitation tests as well as the foam index method. The extraction of the alkaloids was carried out with organic solvents in a basic medium while the purification by open column chromatography. The evaluation of the antisickling activity was carried out by Emmel’s test. Results: The chemical screening highlighted alkaloids, steroids, saponins, tannins, and terpenoids in the species studied. Flavonoids and anthocyanins were present in organs of Macaranga schweinfurthii, but absent in Cremaspora triflora. The extraction showed that Macaranga schweinfurthii leaves contained 0.59% alkaloids and 0.73% alkaloids in Cremaspora triflora leaves. The alkaloids purification allowed to obtain an alkaloidal fraction MS1 (1.24 g, 70.05%) from Macaranga schweinfurthii and two fractions [CT2 (0.934 g, 63.97%) and CT3 (0.006 g, 0.41 %)] from Cremaspora triflora which tested positive with Dragendorff and Wagner reagents. The antisickling activity evaluation showed that the SIR varied between 36.00% (0.25 mg/ml) and 90.66% (1 mg/ml) for the alkaloid solutions of Cremaspora triflora (IC50 of 0.51 mg/ml) as well as between 4.00% (0.25 mg/ml) and 33.33% (1 mg/ml) for the alkaloid solutions of Macaranga schweinfurthii (IC50 of 1.40 mg/ml). Conclusion: This study showed that the purified alkaloids of the studied plant species have an inhibitory power on sickling.

Résumé :

The aim of the present study was to evaluate the Chemical composition and bioactivity of Anthocleista schweinfurthii Gilg (Gentianaceae) fruits, leaves, root bark and stem bark extracts against Sickle cell disease (SCD) and associated bacteria. The antisickling and antibacterial activities were carried out using Emmel and micro-dilution methods respectively. The results revealed that the fruits, leaves, root bark and stem bark extracts of A. schweinfurthii contains various secondary metabolites such as the alkaloids, saponins, total polyphenols, flavonoids, tannins, anthocyanis, leuco-anthocyanins and quinones. The ethyl acetate and methanol extracts displayed antisickling activity. While, the antibacterial activity of different plant extracts tested was weak toward tested bacterial strains (CMI ≥125μg/mL). The antibacterial activity can be improved by bio-guided fractionation of the n-hexane, ethyl acetate or methanol soluble fraction. This study provides for the first time a scientific basis for the in vitro antisickling activity of A. schweinfurthii.

Résumé :

Cancer and infectious diseases combined are leading cause of death and public health concern. In developing countries, about 80% of the populace depends on medicinal plants for their general health care needs including treatment of infectious diseases and cancer. Aloe schweinfurthii (Aloaceae) is a small medicinal herb that is commonly used for the treatment of cancerous and infectious diseases in South-West Nigeria. The focus of this study was to evaluate the growth inhibitory and antimicrobial activities of the herb. The rind of the herb was collected, air dried, pulverized and extracted into distilled methanol by cold maceration. The dried extract obtained was subjected to growth inhibitory and antimicrobial assays. The extract displayed concentration dependent growth inhibitory activity with IC50 of 484.7±2.16 and 1188±2.32µg/mL compared to cyclophosphamide with IC50 of 174.3±0.19 and 834.5±0.84 µg/mL in Sorghum bicolor radical and Allium cepa root growth inhibitory assays, respectively. The extract displayed concentration dependent antibacterial and antifungal effects with the highest activity against C. freundi (18 mm zone of inhibition) at 50 mg/mL. The extract of Aloe schweinfurthii leaf rind displayed marked growth inhibitory and antimicrobial bioactivities. The extract maybe considered as a viable candidate for discovery of chemotherapeutic agent (s). Keywords: Growth inhibition, Antimicrobial, Aloe schweinfurthii, Chemotherapeutic Agent

Résumé :

The effect of moisture content on some physical properties of three varieties of Canarium schweinfurthii Engl. fruits (small, large and long) was studied at 40.91%, 34.92%, 23.44%, 18.5% and 11.03% moisture content on wet basis in order to solve problems associated with designing and development of processing and handling equipment for these fruits. The physical parameters investigated were major, intermediate, minor diameters, geometric mean diameter, unit mass, volume, sphericity, density, bulk density, roundness, aspect ratio, porosity, surface and specific surface area. The results obtained showed that the physical parameters decreased linearly with a decrease in moisture content. Major diameter and true density of all the fruit varieties were not affected significantly (P < 0.05) by moisture content. Canarium schwein-furthii Engl. fruits are not round but spherical and oblong, hence, they can rather roll than slide. Among the studied varieties, small Canarium schweinfurthii Engl. is less bulky, has the highest specific surface area and is more porous.

Résumé :

Two contrasting forms of Pennisetum belonging to the primary and tertiary gene pools were assessed for genomic organization using in situ hybridization with rDNA probes (18S–5.8S–25S and 5S) on metaphase and interphase cell nuclei. The primary gene pool is represented by diploid (2n = 2x = 14) cultivated pearl millet (Pennisetum glaucum) and its close wild relatives (Pennisetum violaceum and Pennisetum mollissimum). Pennisetum schweinfurthii (2n = 2x = 14) was taken as representative of the tertiary gene pool, owing to its diploid status and its similarity to the accessions of the primary gene pool in chromosome number. Using the 18S–5.8S–25S probe, we observed two sites of distribution in the four species but at different locations. Within the primary gene pool, signals were detected on the telomeric part of the short arm of chromosome pair VI and at the nucleolar organizing region (NOR) of the satellited chromosome pair (VII). Signals were observed at the NOR of the two satellited chromosome pairs (I and IV) of P. schweinfurthii. The 5S probe was detected at the telomeric part of the short arm of metacentric chromosome pair IV of the three species of the primary gene pool, while it occured in an intercalary position on the short arm of chromosome pair II of P. schweinfurthii. These results showed a chromosomal similarity of rDNA sequence locations within the primary gene pool and are in agreement with the high genetic identity between wild and cultivated forms of pearl millet previously revealed by allozyme studies. Implications of genomic organization for genetic resource enhancement are discussed. Key words : Pennisetum, in situ hybridization, rDNA probes, genomic organization.

Résumé :

The viscosity of two varieties of Canarium schweinfurthiiEngl. fruits oil (large and long) were studied at four different temperatures (30, 40, 50 and 60<sup>o</sup>C) and three shear rates (7.91, 15.82 and 39.54 s<sup>–1</sup>). SurgiFriend Medical (model NDJ-5S) viscometer was used to carry out the study. Biodiesel characteristics of the oil were also investigated. The results showed that variety had no effect (P < 0.05) on the viscosity of Canarium schweinfurthii Engl. fruit while temperature had especially at 50<sup>o</sup>C and above. The shear rate of 15.82 s<sup>–1 </sup>(12 rps) gave the lowest oil viscosity for both varieties. The oil from large fruit had the best temperature stability, low percentage viscosity (6.33%) variation and least activation energy (796.51 J·mol<sup>–1</sup>·K<sup>–1</sup>) while long variety had best biodiesel characteristic for safe handling. Temperature had no significant (P < 0.05) effect on the consistency coefficient (C) and flow behaviour index (n) of both varieties of Canarium schweinfurthii Engl. fruits oil. Besides, oil from both fruit varieties is Newtonian fluids.

Résumé :

Aqueous extract bark of Anthocleista schweinfurthii (ASE) was investigated for anti-arthritic, anti-inflammatory activities and phytochemicals screening. Phytochemical screening was carried out according, to LC-MS procedures, the anti-inflammatory effect of ASE was evaluated in vitro inhibition of 15-lipoxygenase (15-LOX) enzyme and proteinase inhibiting action assays. The anti-arthritic activity was performed according to the Bovine Serum Albumin (BSA) test. The chemical composition of ASE showed that it was mainly composed of isocyanate, biphenyltriol, methoxyflavanone, soscoparin and glucopyroside. In the anti-inflammatory assays, ASE showed selective inhibition of 15-lipooxygenase with IC50 value of and moderate activity against the inhibition of proteinase action with IC50 value of L. Both the methods showed that the ASE posses good anti-inflammatory activity. ASE had strong in vitro anti-arthritic activity with IC50 of , the positive control Diclofenac had IC50 value of The result of this study justified the use of this plant in traditional Cameroonian medicine in the treatment of inflammation. ASE may offer a new source of potential therapeutic agents for the effective treatment of arthritis and inflammation.

Résumé :

<p>The adsorption of Cu2+ions on activated carbon based canarium schweinfurthii impregnated with ZnCl2 was studied. The shells of canarium schweinfurthii were impregnated with ZnCl2 at varying ZnCl2 concentrations, temperature, residence time while keeping the heating rate fixed at 10 °C / min and the ratio of impregnation of 1:1. The activated carbon with the highest surface area in term of iodine number of 860,817 mg/g, the highest methylene blue of 741,6 mg/g and 74,66 % of yield of carbon was obtained at 650 °C, 60 % ZnCl 2 and 30min. From the batch adsorption studies, the equilibrium time was found to be 40 min. Analysis of equilibrium isotherm models revealed a good correlation of the experimental data with the Tempkin (R 2 = 0.909) model. This confirms a high affinity of the activated carbon for Cu 2+ ions on the heterogeneous surface. The value of energy obtained from the Tempkin model was 60,606 J/mol and the presence of pics between 487 cm-1 to 871 cm-1 indicating that physisorption and chemisorption were taking place during this sorption. The pseudo-second order kinetics(R 2 = 0.999) governs the adsorption of Cu2+ions on this activated carbon.</p>

Résumé :

The present study was undertaken to investigate the cardiovascular effect of three extracts from the root bark of Anthocleista schweinfurthii Gilg.: an aqueous extract (AE), a dichloromethane extract (DCMR) and a fraction enriched in cardiac glycoside type compounds (CARDAN). In isolated perfused frog heart, bolus injection of the extracts produced a positive inotropic effect. The responses to AE and DCMR, but not to CARDAN, were depressed by propranolol. In isolated rat aorta, DCMR produced a transient increase in contractile tension while AE and CARDAN induced a sustained constriction. AE vasoconstrictor effect was abolished by phentolamine, while contraction evoked by CARDAN was antagonized by verapamil. In aortic rings contracted in low K+ media, the addition of K+ evoked a relaxation, which was abolished by ouabain, depressed by DCMR but not affected by either AE or CARDAN. These observations indicate that Anthocleista schweinfurthii contains substances that promote vasoconstriction and increase cardiac contraction. The effect of DCMR was only partially mediated by inhibition of the Na+ pump while the mechanism of action of AE and CARDAN was distinct from the inhibition of the Na+,K+-ATPase pump, but could involve adrenergic receptors, or either direct or indirect activation of L-type calcium channels.

Résumé :

SUMMARYTo address the molecular diversity and occurrence of pathogenic species of the genusEntamoebaspp. in wild non-human primates (NHP) we conducted molecular-phylogenetic analyses onEntamoebafrom wild chimpanzees living in the Issa Valley, Tanzania. We compared the sensitivity of molecular [using a genus-specific polymerase chain reaction (PCR)] and coproscopic detection (merthiolate-iodine-formaldehyde concentration) ofEntamoebaspp. We identifiedEntamoebaspp. in 72 chimpanzee fecal samples (79%) subjected to species-specific PCRs for sixEntamoebaspecies/groups (Entamoeba histolytica, Entamoeba nuttalli, Entamoeba dispar, Entamoeba moshkovskii, Entamoeba coliandEntamoeba poleckiST2). We recorded threeEntamoebaspecies:E. coli(47%),E. dispar(16%),Entamoeba hartmanni(51%). Coproscopically, we could only distinguish the cysts of complexE. histolytica/dispar/moshkovskii/nuttalliandE. coli. Molecular prevalence of entamoebas was higher than the prevalence based on the coproscopic examination. Our molecular phylogenies showed that sequences ofE. disparandE. colifrom Issa chimpanzees are closely related to sequences from humans and other NHP from GenBank. The results showed that wild chimpanzees harbourEntamoebaspecies similar to those occurring in humans; however, no pathogenic species were detected. Molecular-phylogenetic methods are critical to improve diagnostics of entamoebas in wild NHP and for determining an accurate prevalence ofEntamoebaspecies.
