title: A new cytisine-type alkaloid from the stem bark of Maackia amurensis.
abstract: One new cytisine-type alkaloid, [(3-hydroxy-6-pyridinyl)-methyl]-cytisine (1), was isolated from the stem bark of Maackia amurensis, together with five known alkaloids: cytisine, N-formylcytisine, N-(3-oxobutyl)cytisine, (-)-epibaptifoline and N-methylcytisine. The structure of 1 was elucidated based on spectral methods (IR, CD, 1D and 2D NMR, HR-ESI-MS and EI-MS).
