The phytochemical investigation carried out on five medicinal plants of Ivory Coast, used in the traditional treatment of the tooth decay first focused on the research of their chemical composition. The latter has resulted in the demonstration of several biomolecules (sterols, flavonoids, tannins, etc.), which have signed a good antioxidant profile. In a second time, it was devoted to the quantification of certain phytophenols. The results of this work indicated variable and significant levels overall. The stems of Ximenia americana exhibited the best antioxidant activity, which activity is dependent on its total phenolic compound rich (8802.94 ± 298.54 μgEAG / g), total flavonoids (18.39 ± 0.87%) and condensed tannins (99,369 ± 1,485 μgECT / mg).
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.
