Description:

Tutin in honey, is a plant-derived neurotoxin.

Sweet Poisons: Honeys Contaminated with Glycosides of the Neurotoxin Tutin.[Pubmed: 25993882]

Poisonings due to consumption of honeys containing plant toxins have been reported widely. One cause is the neurotoxin Tutin, an oxygenated sesquiterpene picrotoxane, traced back to honeybees (Apis mellifera) collecting honeydew produced by passionvine hoppers (Scolypopa australis) feeding on sap of the poisonous shrub tutu (Coriaria spp.). However, a pharmacokinetic study suggested that unidentified conjugates of Tutin were also present in such honeys.
METHODS AND RESULTS:
We now report the discovery, using ion trap LC-MS, of two Tutin glycosides and their purification and structure determination as 2-(β-d-glucopyranosyl)Tutin (4) and 2-[6'-(α-d-glucopyranosyl)-β-d-glucopyranosyl]Tutin (5). These compounds were used to develop a quantitative triple quadrupole LC-MS method for honey analysis, which showed the presence of Tutin (3.6 ± 0.1 μg/g honey), hyenanchin (19.3 ± 0.5), Tutin glycoside (4) (4.9 ± 0.4), and Tutin diglycoside (5) (4.9 ± 0.1) in one toxic honey. The ratios of 4 and 5 to Tutin varied widely in other Tutin-containing honeys.
CONCLUSIONS:
The glycosidation of Tutin may represent detoxification by one or both of the insects involved in the food chain from plant to honey.

Human pharmacokinetic study of tutin in honey; a plant-derived neurotoxin.[Pubmed: 25084484]

Over the last 150 years a number of people in New Zealand have been incapacitated, hospitalised, or died from eating honey contaminated with Tutin, a plant-derived neurotoxin.
METHODS AND RESULTS:
To investigate the basis of this variability a pharmacokinetic study was undertaken in which 6 healthy males received a single oral dose of Tutin-containing honey giving a Tutin dose of 1.8 μg/kg body weight. The serum concentration-time curve for all volunteers exhibited two discrete peaks with the second and higher level occurring at approximately 15 h post-dose. Two subjects reported mild, transient headache at a time post-dose corresponding to maximum Tutin concentrations. There were no other signs or symptoms typical of Tutin intoxication such as nausea, vomiting, dizziness or seizures. Pharmacokinetic analysis using a two-site absorption model resulted in a good fit to the observed concentration data.
CONCLUSIONS:
A novel analytical method subsequently revealed the presence of glycoside conjugates of Tutin in addition to unconjugated Tutin in honey. These pharmacokinetic data will be important to better define a safe maximum Tutin concentration in honey.
