From the roots of Delphinium giraldii, three new lycoctonine-type C19-diterpenoid alkaloids, giraldine D (1), giraldine E (2) and giraldine F (3), have been isolated. The structures of 1～3 were established by spectroscopic evidence including 2D NMR spectroscopy.

摘要

The new compound hemsleyatine (1) was isolated along with four known C19-diterpenoid alkaloids: indaconitine (4), yunaconitine (5), chasmanine (6), and talatisamine (7) from the roots of Aconitum hemsleyanum PRITZ. Structures were established by spectral analysis, including tow dimeusional (2D) NMR spectroscopy and a chemical method. Hemsleyatine (1) is the first C19-diterpenoid alkaloid bearing the 8-amino group. In addition, the assignments of some 13C signals for pseudaconine (3) were revised by comparison with those of hemsleyatine (1).

摘要

Further investigation of the roots of Delphinium giraldii DIELS led to the isolation of three new C19-diterpenoid alkaloids, giraldines G (1), H (2), and I (3). The structures of 1-3 were established based on spectroscopic evidence.

摘要

Three new norditerpenoid alkaloids, trifoliolasines A (1), B (3), and C (5), were isolated from the whole plant of Delphinium trifoliolatum FINET et GAGNEP, and their structures were established based on the spectral data.

摘要

Three new C19-diterpenoid alkaloids, giraldines A (1), B (3) and C (4), were isolated from the roots of Delphinium giraldii Diels, together with three known C19-diterpenoid alkaloids, di-hydrogadesine (5), tatsiensine (6) and siwanine A (7), as well as their structures were elucidated by chemical evidence and spectral analyses, including IR, MS, 1D NMR and 2D NMR.
