Investigation of the aerial parts of Delphinium albiflorum resulted in the isolation and identification of deacetylheterophylloidine [1] along with hetidine [2] and lycoctonine [3] Structure 1 for this previously unreported naturally occurring alkaloid was established on the basis of detailed nmr spectral studies and chemical correlation with deacetylheterophylloidine, obtained by the hydrolysis of heterophylloidine [4]. 1H- and 13C-nmr chemical shift assignments for 1 and 2 are reported herein. © 1995, American Chemical Society.
