'''Pyrrolizidine''' is a heterocyclic organic compound. Formally, it is a saturated derivative of pyrrolizine.
Pyrrolizidine forms the central chemical structure of a variety of alkaloids known collectively as pyrrolizidine alkaloids.<ref>[http://www.genome.jp/kegg-bin/get_htext?htext=br08003.keg&filedir=%2ffiles&extend=A1&open=B10#B10 Pyrrolizidine alkaloids] at KEGG {{Webarchive|url=https://web.archive.org/web/20160303182232/http://www.genome.jp/kegg-bin/get_htext?htext=br08003.keg&filedir=%2Ffiles&extend=A1&open=B10#B10 |date=2016-03-03 }}</ref> It is one of five classes of iminosugars.
