[Cantharidin and its detection in forensic toxicology].

Experimental detection of deadly toxic cantharidin C10H12O4 by chemical analysis was performed in imagoes of two species of cryptotoxic Meloidae beetles--Lytta vesicatoria and Mylabris variabilis. Samples were processed by extraction and sublimation and analyzed by gas chromatography. Graphic documentation proved the presence of cantharidin. A part of microcristalline sublimate was studied microscopically and determinant features of crystalline cantharidin were identified. Moreover, cantharidin levels in single body parts of the beetle were investigated.
