The daphnetoxin is a vegetable toxin . Chemically, it is the benzoic acid - Orthoester a diterpenoid .
Occurrence
Daphnetoxin occurs mainly in the bark, and to a lesser extent in the seeds of various daphne species . The name of the compound was derived from the scientific name of the genus Daphne . The seeds of the real daphne ( Daphne mezereum ) contain z. B. 0.02% daphnetoxin.
Biological importance
Due to the content of daphnetoxin and the chemically related compound mezerein (from Daphne mezereum ), seeds and bark, but also other parts of the daphne's plant, are highly toxic. In humans, poison can also be absorbed through the skin . In addition to severe inflammation at the point of contact, severe damage to the kidneys, the circulatory system and the central nervous system occurs. Some birds like thrushes and wagtails appear to be immune to the venom.
