A new diterpenoid alkaloid, macroyesoenline ( 1 ), and a new norditerpenoid alkaloid, 9‐hydroxyvirescenine ( 2 ), have been isolated from the roots of Aconitum yesoense var. macroyesoense. Their structures were elucidated on the basis of spectral data (1D‐ and 2D‐NMR experiments) and mass spectrometry. The known norditerpenoid and diterpenoid alkaloids delphinifoline ( 3 ) and cochlearenine ( 13 ) were isolated for the first time from this plant.
