GC×GC-HRTOFMS to better understand cloak-and-dagger activities of Madagascar Mantella frogs

Nowadays, there are 16 named species of Mantella frogs. However, some other species are waiting for the determination of their status. These frogs are currently endangered by the lost of their habitats and the poaching. These frogs are collected for the international pet trade for their small size (less than 5 cm) and the iridescent color of their skin. These aposematic colorations result from particular toxic secretions. Their skin poisons mainly contain mixtures of alkaloid molecules. These mixtures have been reported to vary according to geographical location, season, and diet of the frog [1-2].
