Abstract
From the aerial parts of Aconitum balfourii Stapf nine norditerpenoid alkaloids: condelphine (1), bullatine C (2), neoline (3), isotalatizi- dine (4), 1-O-methyldelphisine (5), pseudaconitine (6), yunaconitine (7), bikhaconitine (8), and indaconitine (9), were isolated. The iden- tity of these alkaloids was determined by comparison of mp, tlc and ir spectra with those of authentic samples and the carbon-13 nmr spectra of 2, 5, 6, 7 and 8 with the published chemical shifts. Detailed nmr spectral studies (1H, 13C, 1H homonuclear COSY, HETCOR, and selective INEPT) carried out on (1), (3), (4) and (9) have provided accurate chemical shift assignments for these alkaloids.
