Enquête Ethnobotanique Sur La Prise En Charge Traditionnelle De L’infertilité Féminine Dans La Région Sanitaire Des Savanes Au Togo

Introduction: The management of female infertility by the conventional medicine is very expensive and its coast is unavailable for the very poor populations. In Africa, an important recourses of medicinal plants are available for health care. Objective: The present study was led to recorder traditional remedies use to treat female infertility in the Sanitary Savannas Region of Togo. Methodology: For data collection, semi interview was used. Data were processed and analysed using ethnobotanical quantitative index. The Selection by Progressive Elimination (SPE) was essentially used for the choice of species. Results: With 51 practitioners interviewed, 79 recipes constituted by 87 species belonging to 48 botanical families were collected. Combretaceae (12,64 %) and Rubiaceae (5,7 %) were the most frequent families. Trees (36,78 %) and shrubs (27,58%) were the main ports. Roots (29,17 %) and leaves (27,5 %) were the most used parts. Recipes were prepared frequently by decoction (51,88 %) and powder (38,12%), and were principally taken orally (47,28 %) and by body bath (43,48 %). Sexually transmitted infections (STI) (143 citations) and Painful menstruations (PM) (108 citations) were the most frequent pathologies. The highest Informants consensus factors were 0,61 and 0,56 respectively for STI and PM. The most important Fidelity degrees was 25,49 % for STI related to Capsicum frutescens and Piper guineense. Related to Aframomum melegueta, Piper guineense and Zanthoxylum zanthoxyloides the Fidelity degree was 19,61% for PM and STI. Blighia sapida, Ganoderma colossus, Kigelia africana and Mangifera indica were selected. Conclusion: Plants with highest fidelity degree and those selected by SPE will be subjected to laboratory tests

Maize Fungal Growth Control with Scopoletin of Cassava Roots Produced in Benin

The chemical contamination of food is among the main public health issues in developing countries. With a view to find new natural bioactive products against fungi responsible for chemical contamination of staple food such as maize, the antifungal activity tests of scopoletin extracted from different components of the cassava root produced in Benin were carried out. The dosage of scopoletin from parts of the root (first skin, second skin, whole root, and flesh) was done by High Performance Liquid Chromatography. The scopoletin extract was used to assess the activity of 12 strains (11 strains of maize and a reference strain). The presence of scopoletin was revealed in all components of the cassava root. Scopoletin extracted from the first skin cassava root was the most active both as inhibition of sporulation (52.29 to 87.91%) and the mycelial growth (36.51–80.41%). Scopoletin extract from the cassava root skins showed significant inhibitory activity on the tested strains with fungicide concentration (MFC) between 0.0125 mg/mL and 0.1 mg/mL. The antifungal scopoletin extracted from the cassava root skins may be well beneficial for the fungal control of the storage of maize

Preliminary Phytochemical Screening and Antimicrobial Activity of the Hydroethanolic Extract of the Fruits of Solanum torvum (Swartz) (Solanaceae) Use as Vegetable in Togo

The fruits of Solanum torvum (Swartz), a vegetable-fruit, are used in traditional medicine in Togo in the treatment of infectious diseases and as an anti-anemic. This study then focused on the antimicrobial activity assessment of the hydroethanolic extract of these fruits in the interest of contributing to the valorization of this Togolese flora’s species. A hydroethanolic extraction (50 % - 50 %: v/v) was performed followed by preliminary phytochemical tests. Antimicrobial activity was determined on fourteen bacterial strains using the agar diffusion method. Qualitative phytochemical screening revealed the presence of alkaloids, reducing compounds, tannins, cardiac glycosides, flavonoids, coumarins, triterpenes, saponins, total carbohydrates and free quinones. The extract was active on the reference strains of S. aureus, E. coli, S. pneumoniae and P. aeruginosa. However, this activity was only observed on clinical strains of S. pneumoniae and P. aeruginosa. The extract showed MICs of 25 and 50 mg/ml and BMCs of 50 and 100 mg/ml respectively for S. pneumoniae and P. aeruginosa. The MBC/MIC ratio for these two strains was 2. These fruits would then have bacteriostatic activity on S. pneumoniae and P. aeruginosa. The antibacterial properties of the extract on these germs could justify the use of this plant in traditional medicine for the treatment of certain bacterial infections.

Identification de deux phytostérols biologiquement actifs de l’extrait cyclohexanique des feuilles de <i>Ficus sur</i> (Moraceae)

Ficus sur est une plante alimentaire couramment utilisée en médecine traditionnelle au Togo. Elle a cependant fait l’objet de très peu d’études phytochimiques. Le présent travail a pour but de valoriser cette espèce à travers l’identification continue de ses métabolites. Ainsi, l’extraction cyclohexanique au Soxhlet a été réalisée sur les feuilles de Ficus sur. Cet extrait cyclohexanique obtenu a été ensuite fractionné puis purifié par chromatographie sur colonne de gel de silice. L’identification des composés a été réalisée par GC-MS, précédée quelquefois d’une étape de dérivatisation. Treize fractions (A1 à A13) ont été obtenues du fractionnement de cet extrait. Après deux purifications successives de la fraction A5, deux sous-fractions A5.1 et A5.2 ont été obtenues. Le spectre de masse d’un composé de A2 présente un pic moléculaire à m/z 426 et des pics fragments [M-69]+, [M-154]+, [M-169]+, [M-197]+, [M-208]+ et [M-219]+ caractéristique du taraxastérol. Pour A5.2 dérivatisée, un composé présente un spectre de masse de pic moléculaire à m/z 486 et des pics fragments [M-90]+, [M-129]+ et [M-357]+ propres au β-sitostérol triméthylsilyl éther dérivé du β-sitostérol. La présence de ces deux phytostérols bioactifs serait un atout majeur dans l’usage thérapeutique de cette plante.© 2017 International Formulae Group.

However, few phytochemical studies of this species are available. This work aims at contributing to the enhancement of this approach through an identification of its metabolites. The leaves of Ficus sur were then extracted with cyclohexane using soxhlet. The obtained cyclohexane extract was fractionated and purified by chromatography on silica gel column. Identification of the compounds was carried out by GC-MS, sometimes preceded by a derivatization step. Thirteen fractions (A1 to A13) were obtained from the fractionation of this extract. After two successive purifications of the fraction A5, two subfractions A5.1 and A5.2 were obtained. The mass spectrum of a compound of A2 has a molecular peak at m/z 426 and peaks [M-69]+, [M-154]+, [M-169]+, [M-197]+, [M-208]+ and [M-219]+ characteristic of taraxasterol. For the derivatized fraction A5.2, a compound has a mass spectrum of molecular peak at m/z 486 and peaks [M-90]++ and [M-357]+ characteristic of β-sitosterol trimethylsilyl ether derived from β-sitosterol. The presence of these two bioactive phytosterols would be a major asset in the therapeutic use of this plant.© 2017 International Formulae Group.
