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
The occurrence of the cardiotoxin taxine (comprising taxine B and several other basic taxoids) in leaves of Taxus baccata L. (European yew) is well known and has led to public concerns about the safety of eating or drinking from utensils crafted from the wood of this poisonous species. The
Four prisoners drank a decoction of yew (Taxus baccata) needles containing the toxic alkaloid taxine++ B. Two died in prison (one in the cell, the other shortly after admission to prison hospital, death was caused in both cases by cardiac arrest). Two other prisoners were admitted to the Warsaw
The aim of the experiment was to develop a method of the identification of taxines (taxine B and isotaxine B) from Taxus leaves and its application to the analysis of biological samples collected from the deceased girl. The object of the investigation was the analysis of taxines in post-mortem
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
This method development was to confirm the fatal ingestion of toxic yew plant material in postmortem samples (stomach content, urine, femoral blood, cardiac blood, bile, and brain tissue) collected from a 22-year-old man who committed suicide by ingesting yew leaves. The analytical method was based
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
Taxus baccata is a widely distributed yew often associated with cases of fatal intoxication, which is related to the high amounts of cardiotoxic alkaloids, taxine A and taxine B, contained in its leaves. In this paper, a case of Taxus fatal poisoning, hypothesized by the forensic autopsy, has been
A method is described for the analysis of taxine alkaloids by liquid chromatography/mass spectrometry. It is applicable to the detection of taxine alkaloids in the stomach contents of horses in which Taxus poisoning is suspected. Analysis of a leaf extract of Taxus baccata revealed unreported
A semi-quantitative LC-MS method was developed for the detection of the pseudo alkaloids of Taxus baccata (yew) from human body fluids and tissue samples. This method was used to examine the cause of death of a 43-year-old man who died several hours after he drank a decoction of taxus leaves.
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
