Chemical composition of Cinnamosma madagascariensis (Cannelaceae) essential oil and its larvicidal potential against the filariasis vector Culex quinquefasciatus Say
Cinnamosma madagascariensis has many traditional uses including the treatment of epilepsy and malaria. Little is known of the chemical composition of its essential oil (EO) and its bioactivity on mosquitoes. We studied the chemical composition of C. madagascariensis bark and leaf EOs and their larvicidal potential on Culex quinquefasciatus. GC-MS revealed key differences between the chemical volatile profiles of leaves and bark oils. LC50 calculated on C. quinquefasciatus were 61.6 μL L− 1 and 80.1 μL L− 1 for bark and leaf EOs, respectively.
