Title : Case study and phytochemical investigation of zanthoxylum zanthoxyloids and zanthoxylum macrophylum (Rutaceae) In the Central African Republic and Togo: A comparative approach
The study carried out on Z. zanthoxyloids and Z. macrophylum, lays on the program of valorizing phytogenetical resources. It covers monographic and phytochemical study. Inner uses of these resources show as well their importance on the scale of such African countries as Nigeria, Togo, Congo, Ivory Coast, Central African Republic, Benin, Senegal and Mali. Z. macrophylum is the most used species in the treatment of rheumatism. Over all the inner practices, Z. zanthoxyloids is the most used species. Analysis in multiple correspondences (AMC) with a partial contribution of 80% shows that there is a correlation of uses over all countries, except Senegal that has specific uses. Total extracts obtains from the two specific species from the Central African and Togolese flora have various yielding according to different organs. The most important proportions are that Z. macrophylum barks from Togo (20%); Z. zanthoxyloids barks from the Central African Republic (19%); Z. zanthoxyloids barks from Togo (17%) and Z. macrophylum barks and roots from the Central African Republic (16%). The issues of phytochemical tests showed the presence of alkaloids, of tannins, of flavonoids and saponosids in the organs of the two species. Meanwhile, one notices that : there is a total lack of alcaloids in the level of barks; the absence of saponisides in the level of Togolese and Central African Z. macrophylum leaves; tannins are also absent in the barks of Central African Z. zanthoxyloids barks and Togolese Zanthoxylum macrophylum roots. These differences in components according to Togolese and Central African Republic can be explained by chemotics which in a variety of in chemical components due to specific environmental factors of each milieu.
