Bio-analytical study of plants used in traditional medicine in Togo

Abstract : The investigation of plants used for traditional medicine in Togo is complicated as modern techniques are not available. Computer-aided product identification from traditional usage records (CAPITURE) was evaluated in the context of an ethnobotanical survey on the traditional treatment of fungal diseases in Tchamba District (Togo). This method predicted and identified the most biologically active plants out of the 43 species survey-recorded: Pterocarpus erinaceus predicted to be more active against fungi and Daniellia oliveri against bacteria. The plants were then tested against fungi, bacteria and cancer cells. As predicted with CAPITURE, P. erinaceus was more active against fungi and D. oliveri against bacteria. Interestingly, both plants presented activity on cancer cells without being toxic to normal human cells. In a third step, using analytical chemistry, the compounds responsible for the biological activities were identified. Most of those compounds have never been reported in the plant species or in nature at all, with biological activity in the micromolar range. Finally, pharmaceutical technology was used: by nanosizing the powder of the plant organs, a better biological activity was observed in comparison to that of the organic extract. In conclusion, this research led to the discovery of new molecules with an interesting biological activity that will need further and more detailed investigation
