New C19-diterpenoid alkaloids from Aconitum piepunense

Chem Pharm Bull (Tokyo). 2006 Jun;54(6):779-81. doi: 10.1248/cpb.54.779.

Abstract

Two new C(19)-diterpenoid alkaloids, piepunensine A (1) and 18-acetylcammaconine (2), have been isolated from the roots of Aconitum piepunense together with five known alkaloids pengshenine B (3), talatisamine (4), aconosine (5), yunaconitine (6), and talatizidine (7). The structures of the new alkaloids were established on the basis of spectral data (1D- and 2D-NMR, HR-MS).
