Contribution à la connaissance des principes actifs contenus dans les plantes de la flore du Burundi

Abstract

Our work is entitled: "Contribution to the knowledge of the active ingredients contained in the plants of the flora of Burundi". The overall objective of this study is to contribute to the knowledge of the active ingredients of plants in order to constitute a basic work bringing together the results of previous phytochemical research. Particular emphasis was placed on the identification of plants according to their active ingredients, their respective families and species as well as the organs exploited while analyzing their vulnerability. The data was collected on the basis of an inventory carried out on the previous work of dissertations defended at the University of Burundi, Faculty of Sciences, Department of Biology and Chemistry during a period from 1990 to 2017. The results of our study provided a preliminary list of active ingredients contained in the plants already studied of the flora of Burundi. Ninety-six (96) species distributed in eighty-one (81) genera and forty-eight (48) families with the dominance of Asteraceae have been identified. The active ingredient most widely distributed and studied in the plants of the flora of Burundi is tannins with a rate of 28.1%. The most exploited plant organs are the leaves with a rate of 55.6%. In terms of conservation, the species identified as priority threatened plants for domestication, multiplication and conservation at the national level have been listed.
