Pyrrolizidine alkaloids (PA's), potentially toxic natural secondary products, are typically found in the plant family Boranginaceae.  As a member of the family, Dasynotus daubenmirei can be expected to contain PA's.  Dasynotus daubenmirei is a monotypic genus endemic to the central region of Idaho.  Previous work of Dasynotus established the presence of a prominent retronecine-based monoester, MW: 299 Daltons.  The exact structure of the alkaloids found in Dasynotus will be investigated using other chromatographic and instrumental methods including nuclear magnetic resonance spectroscopy (NMR).
