title: Structure elucidation and NMR assignments of an alkaloid from Ixeris chinensis Nakai.
abstract: A new alkaloid, 2-amino-1,6-dihydro-pyridine-5-carbaldehyde (1), together with four known compounds, namely 4-hydroxybenzaldehyde (2), 4-hydroxyacetophenone (3), acetophenone-4-O-β-d-glucoside (4), 2-hydroxyl-6-methoxyacetophenone-4-O-β-d-glucoside (5), were isolated from the CHCl3extract from Ixeris chinensis Nakai. The structures of 1 was elucidated by spectroscopic methods, including UV, IR, HR-ESI-MS and extensive 1D and 2D NMR techniques.
