Etude phytochimique bio-guidee, activites antibacterienne et analgesique de decoctions ethanoliques d'une Mimosaceae de Cote d'Ivoire/Bio-guided phytochemical survey, antibacterial and analgesic activities of ethanolic decoctions of a Mimosaceae from Cote d'Ivoire

The present survey consisted in a first time, to make a biological assessment carrying on the potential antibacterial and analgesic activities of ethanolic decoctions from Schrankia leptocarpa, the whole plant (P) and its different organs: stem (T), roots (R), leaves (F), fruit, as well as stem-roots (TR), roots-leaves (RF), leaves-stem (FT) combinations. It revealed that all excerpts sign a bactericidal activity against 3 strains of Streptococcus mutans, with a MIC ranging from 6.25 mg/mL to 12.5 mg/mL. However, only the excerpt R exhibits a good analgesic activity. In the second time, a phytochemical screening of the excerpt R has been achieved on the basis of bio-guided tests, after which, the presence of various secondary metabolites (free quinones, saponosides, polyphenols, coumarins, flavonoids, gallic tannins, alkaloids) has been put in evidence.
