ROYLEINE,A NEW NORDITERPENOID ALKALOID FROM DELPHINIUM ROYLEI

摘要

A new norditerpenoid alkaloid,royleinine(1) has been isolated from the aerial parts of Delphinium roylei Munz,along with three more norditerpenoid alkaloids,isotalitazidine,condelphine and senbusine-C.The structure of 1 has been established on the basis of its spectroscopic data(IR,HRMS,~1H,~(13)C,~1H-~ 1H-~(13)C COSY and NOESY spectra).
