Pyrrolizidine alkaloids in honey
Parameters (quantitative): Screening for at least 9 different pyrrolizidine alkaloids, e.g. monocrotaline, heliotrine, retrorsine Article Number: 2011006 Description: Honey is one of the major sources for consuming toxic pyrrolizidine alkaloids (PA). PA are present in over 6000 plant species and function as protecting agents against predators. PA are liver-damaging and most likely carcinogen. Therefore, honey with high PA levels should not be sold.
