摘要：

From Colchicum ritchii R.Br (Liliaceae) of Jordanian origin, the new colchicine-type alkaloid (-)-O-methylspeciosine (1), the known alkaloid (-)-speciosine (2) and two new homoaporphine-N-oxides are isolated and characterized: (+)-krevsigine-N-oxide (5) and (+)-szovitsamine-N-oxide (6). Additinally, two photoisomers of the cholchicine alkaloids are identified after their isolation and their H-1 and C-13 NMR data reinvistigated: beta-lumicornigerine (3) and beta-lumidemecolcine (4).
