Chemical characterization of Tectona grandis, Thalia geniculata, Lasiomorpha senegalensis and of Musa acuminata used as food packing’s in Benin

Abstract

Several plant leaves are used like packing in agro alimentary in Benin and play a double role. While acting as packing, they offer an antibacterial protection and/or antifungal to the conditioned food. It is in the research of possible antibacterial potential and/or antifungal of the leaves of Tectona grandis, of Thalia geniculata, of Lasiomorpha senegalensis and of Musa acuminata in traditional use as packing for the conservation of food in Benin that the present survey has been led. It aims to make the phytochemical screening of the leaves concerned. From the gotten results, it notices that the non volatile extracts of the plant species tested contain antibacterial compounds (flavonoïdes, tannins) antifungal (quinonic derivative) and no cyanogenic derivatives is present in somes leaves.
