Pyrrolizidine alkaloids (PAs), sometimes referred to as necine bases, are a group of naturally occurring alkaloids based on the structure of pyrrolizidine

Mediterranean region. Although the plant contains small amounts of pyrrolizidine alkaloids, some parts are edible and its seeds provide oil. B. officinalis

Pyrrolizidine is a heterocyclic organic compound. Formally, it is a saturated derivative of pyrrolizine. Pyrrolizidine forms the central chemical structure

States, where it is an invasive weed. Due to a high concentration of pyrrolizidine alkaloids, it is poisonous to grazing livestock, especially those with

Crotalaria. These plants contain large amounts of toxins, particularly pyrrolizidine alkaloids (PAs), which are found in high concentrations in the seeds

the plant is toxic to horses and cattle through the accumulation of pyrrolizidine alkaloids in the liver. The plant root was used in ancient times as

Pyrrolizidine alkaloidosis is a disease caused by chronic poisoning found in humans and other animals caused by ingesting poisonous plants which contain

It has had uses in traditional medicine, but the discovery of toxic pyrrolizidine alkaloids in the plant has resulted in liver health concerns. Tussilago
