The structure of peregrine ( 1 ), a norditerpenoid alkaloid isolated from Delphinium peregrinum var. elongatum B OISS ., was revised on the basis of the 1 H‐COSY, HMQC, HMBC, and ROESY NMR spectra and of the X‐ray analysis of its parent alcohol 2 . Some of the 13 C‐NMR resonances of 1 and the related alkaloids peregrine alcohol ( 2 ), 14‐ O ‐acetylperegrine ( 3 ), bicoloridine ( 4 ), bicoloridine alcohol ( 5 ), 6‐ O ‐acetylbicolorine ( 6 ), bicolorine ( 7 ), and 14‐ O ‐acetylbicolorine ( 8 ), were also reassigned.
