Ricinodendron heudelotii (Baill.) Heckle is used as food ingredient and in the African traditional medicine. In the present study inhibitory activity on alpha-amylase, alpha-glucosidase, acetylcholinesterase, butyrylcholinesterase, and tyrosinase of ethyl acetate, methanol, and water extracts of R. heudelotii seeds and stem bark were assessed. Stem bark extracts exhibited significant antioxidant properties. Ethyl acetate extract of seed had great inhibitory potential against alpha-glucosidase, acetylcholinesterase, and butyrylcholinesterase. Nuclear magnetic resonance (NMR) and high-performance liquid chromatography with electrospray ionization mass spectrometry (HPLCDAD-ESI-MSn) analysis revealed the presence of catechin and gallic acid derivatives in bark while fatty acid in seeds. Multivariate analysis of obtained data was performed showing a clear separation between seed and stem bark. Obtained results indicate R. heudelotii stem bark as new starting materials for the development of novel pharmaceutical formulations.
