A further study of the alkaloidal constituents of Delphinium cardiopetalum led to the isolation of five new highly functionalized diterpenoid alkaloids, cardiopine, cardiopinine, cardiopimine, cardiopidine and cardiodine. Their structures were established by 1D and 2D NMR spectroscopy, (HCOSY)-H-1, HMQC, HMBC and ROESY, and chemical transformations.
