Özet
Three new alkaloids, oxoincartine, 3,11-O-diacetyl-9-O-demethylmaritidine and 11-O-acetyl-9-O-demethylmaritidine together with seven known compounds namely, incartine, galanthamine, galanthine, 9-O-methylpseudolycorine, N,O-dimethylnorbelladine, hordenine and vittatine were isolated from Galanthus fosteri Baker (Amaryllidaceae). Their structures were elucidated by spectroscopic analyses (UV, IR, MS, CD and 1D/2D NMR). Cholinesterase inhibitory activity potentials of the compounds were also determined.
