Cs. Kim et al., 14-DEOXYPARSONSIANIDINE N-OXIDE - A PYRROLIZIDINE ALKALOID SEQUESTERED BY THE GIANT DANAINE BUTTERFLY, IDEA-LEUCONOE, Bioscience, biotechnology, and biochemistry, 58(5), 1994, pp. 980-981
A new pyrrolizidine alkaloid, 14-deoxyparsonsianidine N-oxide, was iso
lated from adults of a danaine butterfly, Idea leuconoe. The compound
appears to have been incorporated directly from the host plant, Parson
sia laevigata, together with other major analogs, during the larval st
age.
