Abstract

Autopsy findings of fatal intoxication with yew (Taxus baccata) are nonspecific. A presence of plant residues in the digestive tract can signalize yew intoxication. If yew decoction is consumed, plant residues are not found. In such a case the intoxication can be signalized by the presence of 3,5-dimethoxyphenol in biological material. Authors of this article describe the proof and quantification of the 3,5-dimethoxyphenol in two cases of fatal intoxication with yew. In both cases the liquid/liquid extraction and solid phase extraction was used. Extracts obtained from the acidic and basic environment were analysed. Extracts from the acidic environment were methylated and the extracts from the basic environment were acetylated. The analyses were carried out by gas chromatography/mass spectrometry. In the blood of both intoxicated persons the presence of 3,5-dimethoxyphenol was proved and its concentration 82 ng/ml and 417 ng/ml was quantificated. In both cases the presence of 3,5-dimethoxyphenol was also proved in the gastric contents and urine.
