The emergence of multidrug bacterial resistance poses a great public health problem and requires a constant search for new antibacterial agents. However, Niger’s flora possesses several medicinal plants used in traditional medicine to cure infectious diseases and can be used as sources of bioactive ingredients. This current study was designed to evaluate the antibacterial activity of eight plants used in the traditional pharmacopeia of Niger. The extracts were prepared by maceration using ethanol, methanol, and distilled water. The obtained extracts were screened against Salmonella spp., Shigella spp., and Escherichia coli using the microdilution method coupled with a resazurin-based assay. Phytochemical screening was performed using colorimetry, while the quantification of total polyphenols, total flavonoids, and total tannins was determined by spectrophotometry. Out of the eight plants obtained, five named Cassia italica, Limeum pterocarpum, Phyllanthus pentandrus, Strychnos innocua, and Ximenia americanum exhibited antibacterial activity with MICs ranging from 500 μg/mL to 2000 μg/mL. Phytochemical screening showed the presence of alkaloids, saponosides, tannins, flavonoids, terpenes/sterols, quinones, and polyphenols. The ethanolic and methanolic extracts of X. americana contained important quantities of total polyphenols, with 43.59 ± 0.15 and 41.97 ± 0.02 mg EAG/100 mg of extract, respectively. These extracts showed the highest contents of total tannins at 46.49 g/L and 45.52 g/L, respectively. For total flavonoids, the highest content was obtained with the methanolic extract of P. pentandrus, with 3.12 ± 0.01 mg QE/100 mg of extract. These findings justify the uses of these plants in traditional medicine for the treatment of infectious diseases such as diarrhea and can be used as starting points for the development of phytodrugs against infectious diarrhea.

Guiera senegalensis (Combretaceae), Commiphora africana (Burseraceae), Schwenckia americana (Solanaceae) are plants used in traditional medicine against malnutrition. The objective of this study is to contribute to the valorisation of these three species used in the management of malnutrition in children aged 0 to 5 years in Niger. The chemical composition of the extracts of these plants was determined using standard methods. The contents of total polyphenols, total tannins and antioxidant activity were determined by the spectrophotometric method. The determination of total polyphenols on the extract of the bark of C. africana gave the highest content of 86.62±6.31 mg EAG/g. For total tannins, high levels were observed with the bark extract of C. africana (16.14±0.95 g/L). The determination of the reducing power showed the highest activity with the leaf extract of G. senegalensis (2±0.04 mmol EAA/g). The analysis of the overall chemical composition showed that the extract of G. senegalensis leaves is richer in proteins (11.38%) and lipids (4.02%). The highest carbohydrate content (72.47%) is observed in the bark extract of C. africana. For the overall ash content, the whole plant extract of S. americana has the highest ash content at 11.04%. Extract from the leaves of G. senegalensis gave the highest dry matter content (92.42%). These results could contribute to the formulation of fortified foods used to improve the nutritional status of children in particular and populations in general.

Ethnopharmacological properties of the fern Adiantum lunulatum: A Review

Adiantum lunulatum (Hamsapadhi) is a cosmopolitan tropical fern that is traditionally employed in folklore medicine to address various maladies. The fern is a reservoir for major plant secondary metabolites like tannins, saponins, alkaloids, phenolics flavonoids, etc. Accredited the presence of phytochemicals the fern portrays pharmacological properties like antimicrobial, antifertility, hepatoprotective, anti-ulcerative, antipyretic, gastroprotective properties, etc. Despite numerous evidences of pharmacological applications in traditional medicines, there are very few in vitro and in vivo studies on the fern to corroborate its pharmacological properties and to appraise it as a prospective therapeutic agent, thus necessitating more research in this fern. The current review circumscribes the phytochemistry of the fern and its concomitant pharmacological properties.
