“…Aqueous and methanolic extracts of seeds of Cucurbita moschata tested on LMI assay, using the same parasite showed similar results with 21.32% and 33.53% respectively Marie-Magdeleine et al [36]. Moreover Olounlade [39] showed that the inhibition effect of acetonic, ethanolic and chloroformic extracts of Newbouldia laevis and Zanthoxylum zanthoxyloïdes on LMI assay were less than 30% at the same concentration and on the same parasite. However the result obtained with the aqueous extract of C. crepidioides leaves was less than those obtained with the aqueous and ethanol extracts of Aristolochia indica as reported by Mini et al [2] on larvae migration.…”

“…Brunet et al [38] showed that the extract of safoin (plant rich in tannins) affects the kinetics of unsheathing of stongyle L3. In additional Olounlade et al [39] showed that the inhibition of larval migration of H. contortus was due to tannins from Z. zanthoxyloides and N. laevis. According to Hoste et al [40] the effectiveness of these tannins depend on their structure: condensed tannins have anthelmintic activity with varied possible mechanism of actions most especially its astringent property.…”

Objectives: Gastrointestinal parasites are recognized as major constraint to livestock production throughout the tropics. The use of plants and plant extracts remain the most serious alternative to modern anthelmintic drugs. This study evaluates the in vitro anthelmintic activity of aqueous leaves extract of Crassocephalum crepidioides against Haemonchus contortus. Methods: Aqueous extract at concentrations of 75 to 2400 µg/ml was tested in vitro on three development stages of H. contortus using egg hatch assay (EHA), larval migration inhibition assay (LMIA) and adult worms motility inhibition assay (AMIA). Results: EHA showed significant reduction (P < 0.05) on H. contortus egg hatch. The inhibition of egg hatching was concentration dependent with the greatest inhibition (50.52%) at the highest concentration (2400 µg/ml) of the extract. Thiabendazole used as positive control showed significant inhibition (P < 0.001) with rate of 76.68 % at the highest concentration (500µg/ml). On LMIA the extract significantly (P < 0.05) inhibited larval migration of L3 in a concentration dependent manner compared to Phosphate Buffered Saline, but less than levamisole (P < 0.001). The highest inhibition rate was 35.30 % at the concentration of 1200 µg/ml. The addition of polyvinylpolyrrolidone to the aqueous extract slightly reduces (4.9%) the inhibition of the effect induced by the extract on larval migration. Effect of extract on AMIA was concentration-dependent with significant increase (P < 0.05) in percentage of inhibition after 12 h. Levamisole (500 µg/ml) kills 100% worms after 18 h post-exposure but by this time the plant exhibited only 16.67% inhibition at the highest concentration (2400 µg/ml). Conclusion: These finding indicate that C. crepidioides leaves have anthelmintic properties against H. contortus. This activity may be due to secondary metabolites such as saponins, flavonoids and tannins present in the extract. Further studies are needed to evaluate deeply the anthelmintic potential of this plant.

“…Elles sont prometteuses dans la collecte des radiations solaires, ce qui permettrait leur large utilisation dans les cellules solaires à pigments photosensibles. En plus, ces pigments végétaux ont, grâce à leurs groupes fonctionnels d'ancrage (hydroxyle, carboxyle), la capacité de se lier aisément de manière covalente avec les nanoparticules du semi-conducteur (Olounladé et al, 2011;Calogero et al, 2012;Narayan, 2012 (Bartley et al, 1995;Mortensen, 2006).

Nos sincères remerciements vont au Ministère fédéral de l'éducation et de la recherche allemand (BMBF) et au Centre des services scientifiques de l'Afrique de l'Ouest sur les changements climatiques et l'utilisation des terres adaptées (WASCAL) pour leur bourse partielle. RESUME Les cellules solaires à pigments photosensibles semblent être le dispositif photovoltaïque d'avenir. Toutefois, la toxicité et le coût de synthèse des pigments limitent l'utilisation accrue desdits prototypes. Les pigments naturels végétaux peuvent constituer une alternative efficace, durable et bon marché. Dans cette étude, l'enquête ethnobotanique des plantes traditionnellement utilisées dans la teinture (textile, maroquinerie, poterie et esthétique) a été réalisée auprès des herboristes, des artisans teinturiers, des chercheurs nigériens et des tradipraticiens de la région de Niamey. Par la suite, le criblage phytochimique, via des réactions colorées et/ou de précipitations de vingt plantes les plus citées, a été réalisé. L'enquête ethnobotanique a permis de répertorier une quarantaine d'espèces végétales qui sont utilisées dans la production des colorants. Ces plantes sont réparties dans 23 familles dont les plus dominantes (62,5% des espèces recensées) sont les Caesalpiniaceae (12,5%), les Combretaceae (10%), les Fabaceae (10%), les Anacardiaceae (10%), les Poaceae (5%), les Cochlospermaceae (5%), les Méliaceae (5%) et les Mimosaceae (5%). Des tannoïdes, flavonoïdes, anthocyanes, quinones, coumarines, alcaloïdes, stérols et polyterpènes sont détectés dans les extraits de ces plantes. L'abondance remarquable des diverses molécules colorantes fait de ces plantes des matières premières potentielles pour la production des colorants naturels valorisables en énergie solaire, particulièrement dans les cellules solaires à pigments photosensibles.

Background: Small ruminant health problems still represent a major constraint in Benin. Thus, to treat goats and sheep diseases, breeders use medicinal plants. However, little scientific work has been done on the traditional knowledge of these plants.The specific objectives of the current study were (i) to document the traditional knowledge regarding the disease groups treated and the medicinalplants used in the health and zootechnical management of small ruminants in Benin and (ii) to assess the effect of sex, ethnicity, agroecological zone and herd sizeassociatedwith them. Methods: To achieve these objectives, an ethnoveterinary survey was conducted in different agroecological zones from September 2018 to February 2019. A semi-structured questionnaire was administered to 506 breeders and farmers and took into account the identity of the respondents, the plants used to treat the ailmentsfor improving the productivity of sheep and goats, the parts used and the method of preparation of the recipes. The data were analyzed through the calculation the Relative Frequency of Citation (RFC), Fidelity Level (FL), and Consensus Factor of the Informant (CFI). Descriptive statistics and multivariate analyses were applied to our data using the software R and Minitab. The symptoms recordedfrom the respondents were categorized into 10 disorder groups using the second version of the International Classification of Primary Care (ICPC). Results: Ten (10) categories of disorders were treated by the people surveyed. These are mainly disorders of the digestive system (D) (49.34%) and disorders related to pregnancy and parturition (W) (20.15%). A total of 101 species medicinal plantsbelonging to 42 families and 90 genera were recorded. The most represented families are Leguminosae (21.57%) and Euphorbiaceae (6.86%). The most cited speciesare Zanthoxylumzanthoxyloides (Lam.) Watermann, Khayasenegalensis (Desr.) A. Juss, Strigahermonthica (DeliIe) Benth. and Adansoniadigitata L. Sex, ethnicity, agroecological zone and herd size are the socioeconomic and environmental factors that influence the level of ethnoveterinary knowledge. Conclusions: Results showedthe high diversity of medicinal species used to treat small ruminant’sdiseasesin Benin. Chemical and biological analyzes are needed to test the effectiveness of the main inventoried plants. Keywords : Ethnoveterinary, sheep, goats, Benin.
