The Pyrrolizidine Alkaloids

1982
Previous chapters in this series by Warren appeared in 1955 (310) and 1966 (311). Since then an authoritative book by Bull, Culvenor, and Dick, on the chemistry and pharmacology of pyrrolizidine alkaloids has been published (60). Comprehensive reviews on the alkaloids (312), their chemotaxonomic significance (77), and general pyrrolizidine chemistry ...

Efficient Extraction of Pyrrolizidine Alkaloids from Plants by Pressurised Liquid Extraction – A Preliminary Study

Planta Medica, 2019
Pyrrolizidine alkaloids and their corresponding pyrrolizidine alkaloid-N-oxides are secondary plant constituents that became the subject of public concern due to their hepatotoxic, pneumotoxic, genotoxic, and cytotoxic effects.
