Phytochimiques des plantes médicinales utilisées dans la prise en charge des maladies infantiles au SudBénin

Abstract

In southern Benin, medicinal plants are used for the health care of children aged 0 to 12 years. The present study aims to highlight some medicinal plants used in southern Benin to treat childhood diseases including malaria, candidiasis, teething disorders, infant colic and diarrhea. The phytochemical screening of the leafy stems of the selected plants revealed the presence of alkaloids, tannins (gallic and catechic), coumarins, anthocyanins and leuco-anthocyans, quinone derivatives, triterpenoids, steroids, saponosides and reducing sugars. These various metabolites possess various therapeutic properties involved in the treatment of the indicated disorders. This would confirm the therapeutic uses reported by the populations surveyed. However, the evaluation of antimalarial, antibacterial, anti-inflammatory and analgesic activities as well as the toxicity test of the aqueous extract of these plants would be necessary.European Scientific Journal January 2017 edition vol.13, No.3 ISSN: 1857 -7881 (Print) e -ISSN 1857-7431 472Keywords: Phytochemical screening, medicinal plants, infantile diseases, therapeutic property, South Benin. RésuméAu sud du Bénin, des plantes médicinales sont utilisées pour les soins de santé des enfants de 0 à 12 ans. La présente étude se propose de valoriser quelques plantes médicinales utilisées au sud du Bénin pour traiter les maladies infantiles dont le paludisme, la candidose, les troubles de dentition, la colique du nourrisson et la diarrhée. Le criblage phytochimique des rameaux feuillés des 10 plantes retenues révèle la présence d'alcaloïdes, de tanins (gallique et catéchique), de coumarines, d'anthocyanes et de leucoanthocyanes, de dérivés quinones, de triterpénoïdes, de stéroïdes, de saponosides et de sucres réducteurs. Ces divers métabolites possèdent diverses propriétés thérapeutiques pouvant intervenir dans le traitement des troubles indiqués. Ce qui confirmerait l'usage thérapeutique signalé par les populations enquêtées. Cependant l'évaluation des activités antipaludique, antibactérienne, anti-inflammatoire, analgésique de même que le test de toxicité de l'extrait aqueux de ces plantes seraient nécessaires.

Phytochemical analysis and antioxidant potential of Ocimum gratissimum Linn (Lamiaceae) commonly consumed in the Republic of Benin

“…These results are similar with those of [31]. Moreover, these results are partially consistent with the results of [32][33][34]. The results of the first author reveal, apart from the antimicrobials mentioned above, the presence of resins, cardiac glycosides, steroid terpenes, and carbohydrates at different concentrations in the extracts of fresh and dried leaves of the plant.…”

Ethnobotanical Knowledge of Jute (Corchorus olitorius L.) in Benin

“…The work carried out within Ivory Coast [17] and Nigeria [18] had helped to highlight the various indigenous uses of C. olitorius by local people. In Benin too, C. Olitorius is also used for many purposes, but local knowledge about its use is few documented [10][11][12][13][14][15][16][17][18][19].…”

Diversity and Local Uses of Tree Species of Non-Timber Forest Products in Zamay Forest Reserve in Cameroon

“…Leaves, fruits and barks (Figure 3) were the most useful organs in our study site for their medicinal properties. Studies on plant system storage and phytochemistry (Georges et al, 2013;Mangambu et al, 2014;Sahli, 2017;Kouchadé et al, 2017) stated that organ collected on a species is related to the utility searched out by population and local knowledge of the species. Frequent use of leaves is justified by the abundance of chemical groups that they contain.…”
