[Alkaloids from Dactylicapnos scandens Hutch].
OBJECTIVE
To investigate the alkaloids in the roots of Dactylicapnos scanden (D. Don) Hutch.


METHODS
The compounds were isolated by various column chromatographic methods. The structures were elucidated by spectroscopic analysis.


RESULTS
Eight compounds were isolated and identified as d-isocorydine (1), protopine (2), d-magnoflorine (3), d-isocorydine-beta-N-oxide (4), d-corydine-alpha-N-oxide (5), d-corydine-beta-N-oxide (6), 6S, 6aS-N-methyllaurotetanine-alpha-N-oxide (7), and 6R, 6aS-N-methyllaurotetanine-beta-N-oxide (8).


CONCLUSIONS
Compounds 4-8 were isolated from this species and the genus Dactylicapnos for the first time.
