Two new pyrrolizidine alkaloids, ideamines A and B, together with other analogs (lycopsamine and parsonsine) were isolated in the N-oxide forms from adult bodies of the Apocynaceae-feeding danaine butterfly, Idea leuconoe.Ideamine A was characterized as a homolog of lycopsamine, in which the viridifloric acid moiety was replaced by a 2-ethyl-2,3-dihydroxybutanoic moiety.Likewise, ideamine B was identified as a nor-derivative of parsonsine, in which the trachelanthic acid moiety was replaced by a 2-ethyl-2,3-dihydroxybutanoic moiety diastereomeric to the necic acid from ideamine A.
