Abstract

Considerable advances have been made in the study of the pyrrolizidine alkaloids during the few years which have elapsed since the last admirable reviews on this subject were made by Henry (87) in 1949, and by Leonard (III) in 1950, and even since Adams (I) in 1953 gave his excellent summary of the then significant recent findings. The present work attempts to correlate the wealth of chemical evidence which has accumulated on the structures of the alkaloids, as well as their acid and basic fission products, many of which have, now been completely elucidated Furthermore, precise methods have revealed previously supposed individuals to be mixtures or identical with known substances; and where this evidence is seemingly conclusive the correction has been made and new lists compiled.
