Analysis by HPLC of organic extracts of Tapinanthus bangwensis used for the conservation of stocks of Zea mays (Linné) and Vigna unguilculata L. Walf against two principal devastating insects (Sitophilus zeamais and Callosobruchus maculatus)
Journal Title: Scholars Academic Journal of Biosciences - Year 2016, Vol 4, Issue 8
Abstract
The objective is to find the alternate ones with insecticides of synthesis, the extracts of plants are used more and more by the peasants to protect stocks from harvest against the devastating insects. Thus, a chemical analysis by liquid chromatography high efficiency (HPLC) is carried out on the organic extracts, of Tapinanthus bangwensis, tested on Sitophilus zeamaïs and Callosobruchus maculatus. The results of the analysis by HPLC show that the extracts contain polar compounds. These results are corroborated by the phyotochimic tests with the identification of molecules (alkaloids, flavanoides, tannins…) likely to be responsible for this insecticidal activity. Keywords: extracts, Tapinanthus bangwensis, Sitophilus zeamais, Callosobruchus maculatus, stored food products, maize, niébé
