Exudates are substances that ooze out of the pores of diseased and/or damaged tissue in plant that are well-used in flourishing international and local uses in Burkina Faso. Previously, the ethnopharmacological investigations in Center region showed that there are lot of medicinal uses like as old wounds, skin disorders diseases treatment. The current study aims to highlight the antitumoral potential of nine resins form central region. One hundred grams of each resin were placed at -80°C before extraction. The resins were grinded, and the powder was stirred twice with 1L and 500 mL of CHCl 3 respectively for 24h. The antiproliferative effect was determined by using MTT colorimetric assay with chloroformic extracts from resin of each plant and the concentrations which inhibited 50% of cell proliferation (IC 50 ) were determinated graphically. The results showed that the IC 50 of A549 proliferative inhibition was form 5.78 (Lannea microcarpa) to 32.48 µg/mL (Daniellia oliveri) and U373 inhibition IC 50 was from 12.90 (L. macrocarpa) to 41.12 µg/mL (Boswellia dalzielli). The Keratinocytes IC 50 was form 1.57 (L. macrocarpa) to 20.4 µg/mL (Boswellia dalzielli). Interestingly, the resin extract form L. macrocarpa resin was a best source of anticancer compounds for the A549 and U373 following by Bombax costatum resin. In the contrast Commiphora africana (Burseraceae) resin was the less antiproliferation effect. The exudates resin from plants that were a source of bioactive compounds could explain of the medicinal uses like as anti-inflammatory, wound healing, and skin ailments in Burkina Faso.

La carence en vitamine A constitue un problème de santé publique dans les pays en développement et affecte en particulier les jeunes enfants et les femmes en âge de procréer. Le but de cette étude était d'évaluer l’application de la politique nationale en matière de production et d’importation, des huiles végétales raffinées, d’enrichissement obligatoire en vitamine A au Burkina Faso, à travers la détermination de la teneur en vitamine A et de l'indice de peroxyde des huiles végétales vendues sur le marché. Cette étude transversale a été menée dans cinq villes sélectionnées selon la densité de la population. Cinquante-neuf échantillons d’huile ont été achetés dans ces villes pour évaluer la teneur en vitamine A, l'indice de peroxyde et leur conformité aux normes nationales et internationales. Dans l'ensemble, 76,27% des huiles n'étaient pas suffisamment enrichies en vitamine A. Pour l'indice de peroxyde, 3,39% des huiles n'étaient pas conformes. Globalement, 77,97% des huiles n'étaient pas conformes pour ces deux paramètres. Au regard de ces résultats il est nécessaire d’intensifier la lutte contre la mise à la consommation des huiles non enrichies en vitamine A au Burkina Faso. English title: valuation of the vitamin A content and the peroxide value of vegetable oils commonly sold in markets in Burkina Faso Vitamin A deficiency is a public health problem in developing countries and particularly affects young children and women of childbearing age. The aim of this study was to assess the implementation of the national policy on the production and importation of refined vegetable oils and mandatory vitamin A fortification in Burkina Faso, through the determination of the vitamin A content and peroxide value of vegetable oils sold on the market. A cross-sectional study was conducted in five cities selected according to population density. Fifty-nine oil samples were purchased in these cities to assess vitamin A content, peroxide value and compliance with national and Codex standards. Overall, 76.17% of the oils were not adequately fortified with vitamin A. For the peroxide value, 3.39% of the oils did not comply. Overall, 77.97% of the oils did not comply for these two parameters. In view of these results, it is necessary to intensify the fight against the consumption of oils not enriched in vitamin A in Burkina Faso.
