dc.descriptionCeiba pentandra (Malvaceae) is a species popularly known in North Brazil as “sumaúma” that has attracted interest in phytochemical studies due to the diversity of classes of compounds biologically active. The objective of this study was to investigate the chemical constituents present in the wood residues of Ceiba pentandra and to evaluate the antibacterial activity of a purified sesquiterpene lactone against Xanthomonas citri subsp. citri. The isolated compounds were identified based on one-dimensional (1H and 13C) and/or two-dimensional (HSQC and HMBC) NMR analyses, the mixtures of fatty acid were characterized by GC-MS. The chemical constituents identified were steroids (cholest-4-en-3-one, stigmast-4-ene-3,6-dione, β-sitosterol, and stigmasterol); macrolides (des-O-methyl-lasiodiplodine and lasiodiplodine); isocoumarin (4-hydroxymelein); sesquiterpene lactone (isohemigosilicic acid lactone-2-methyl ether); and a mixture of fatty acids (palmitic acid, oleic acid, stearic acid, linoleic acid, and dihydrosterculic acid). The sesquiterpene lactone was evaluated against the bacterium Xanthomonas citri ssp. citri and demonstrated bactericidal and bacteriostatic activities at concentrations up to 400 µg mL-1. Our phytochemical study aggregated knowledge of this wood species originated from plantation sites and found activity bactericide to combat citrus canker.
