Thirty-six constituents were identified. Methyl hexadecanoate (18.8%), farnesyl acetate (17.6%), docosane (9.1%) and methyl linolenate (9.4%) were found to be the main components in the whole aerial parts. This latter was the major compound in the flowers (42.6%) while methyl hexadecanoate (38.3%) and methyl linolenate (22%) were the main components in the stems+leaves. Furthermore, the oils were tested against six Gram-positive and Gram-negative bacteria and four phytopathogenic fungi. The Mantisalca duriaei oils exhibited an interesting antibacterial activity against all strains tested except Pseudomonas aeruginosa but no antifungal activity was detected.
