摘要：

Liriodenine [1], together with anonaine [2] and xylopine [3] as their N-acetyl derivatives, has been isolated from the leaves of Talauma gitingensis, and their H-1-nmr spectra have been fully assigned by 1D decoupling experiments, nOe enhancement, and 2D COSY spectroscopy. This is the first reported occurrence of 2 from the genus Talauma. The N-acetyl derivatives of 2 and 3 are shown to exist in conformational equilibrium.
