Abstract
Objective: This study was conducted to determine the physicochemical characteristics and organic and inorganic contaminants of Parkia biglobosa trunk bark powders collected in four localities (Gonse, Yako, Bobo and Nobere) of Burkina Faso.
Methods: The parameters studied were the physicochemical characters, the contents of heavy metals, pesticides and the microbial quality according to the methods of the European Pharmacopoeia.
Results: The study of these parameters revealed a residual moisture content of less than 10% and a uniform pH, macroscopical character and particle sizes for all raw materials. Total ash ranged from 0.09 to 0.96 for powders from Yako and Bobo, respectively. Contaminant assessment revealed that Parkia biglobosa trunk bark contains high levels of manganese (Mn) and lead (Pb). The microbial analysis shows that the trunk bark powders from Gonse, Yako and Bobo complied with the specifications of the European Pharmacopoeia.
Conclusion: These quality control studies allowed the correct identification, characterization and determination of the appropriate harvesting sites for pharmaceutical production of phytomedicine.
