Pyrrolizidine alkaloids are secondary metabolites, produced by several plant species as protection against insect herbivores. They are common food contaminants in herbs, tea, salad, leafy vegetables and honey. Feed can be contaminated so that the plant products find their way in the food chain indirectly also over meat, milk and eggs.

Pyrrolizidine alkaloids have adverse health effects and were classified as genotoxic, carcinogen and hepatotoxic.
We offer a broad range of pyrrolizidine alkaloids, like Echimidin, Jacobin, Lycopsamin and their N-oxids as analytical standards.
