BACKGROUND
Common yew (Taxus baccata) is a common decorative evergreen shrub with potentially fatal toxicity hallmarked by seizure, arrhythmia and cardiovascular collapse if ingested. Taxine B has been identified as one of the most cardiotoxic taxine alkaloids in Taxus spp, and another alkaloid,

BACKGROUND
European yew (Taxus baccata) is a plant known to man for centuries as it produces many interesting and important metabolites. These chemical compounds were repeatedly analysed by various analytical techniques, but none of the methods used so far allowed the localisation of the chemical

This paper describes two fatalities, three non-fatal intentional and three accidental oral ingestions of yew (Taxus baccata) leaves. In all cases the post-mortem external examinations showed no signs of violence. Internal examinations revealed small green, needle-like particles on the tongue, in the

Taxine B (3), isolated from the dried needles of Taxus baccata, was converted into six novel 7-deoxypaclitaxel analogs, 20, 21a,b, and 23-25, that have structural changes at C1, C2, and C4. A method for the introduction of the benzoyl function at C2, via a benzylidene acetal at C1-C2, will be
Fatal poisoning with Taxus baccata: quantification of paclitaxel (taxol A), 10-deacetyltaxol, baccatin III, 10-deacetylbaccatin III, cephalomannine (taxol B), and 3,5-dimethoxyphenol in body fluids by liquid chromatography-tandem mass spectrometry.

BACKGROUND
Yew (Taxus baccata) is a conifer known to be toxic since ancient times. Taxine A and taxine B, the toxic alkaloids of Taxus, block cardiac sodium and calcium channels causing nausea, vomiting, abdominal pain, cardiac arrhythmias, respiratory distress, coma, seizures, and death in yew

BACKGROUND
Yew plants are evergreen shrubs which are widely spread throughout the northern hemisphere. Taxane alkaloid derivatives, mainly taxine B, represent the main toxins of Taxus baccata and are highly cardiotoxic. Due to the lack of randomized clinical trials, case reports on accidental or

BACKGROUND
The yew (Taxus baccata) is a common evergreen tree containing the toxin taxine B. Between 42 and 91 g of yew leaf is lethal to a 70-kg adult. The objective of this article is to present an overview of findings in fatal yew intoxications.
METHODS
A search using MeSH terms was performed in

OBJECTIVE
Toxic effects of the yew have been known since ancient times. Yew toxicity is due to the content of cyanogenic glycosides and a mixture of alkaloids known as taxines. Taxine B is probably responsible for the most part of adverse effects in poisoned organisms. This particular taxoid is
