Abstract. Aconite is a well-known toxic-plant containing Aconitum alkaloids such as aconitines, benzoylaconines, and aconins. We describe here the distribution of Aconitum alkaloids detected by liquid chromatography-tandem mass spectrometry (LC/MS/MS) in three autopsy cases of suicide by aconite poisoning.
How will you diagnose a case of poisoning?
