[Study on chemical constituents of Delphinium grandiflorum].
OBJECTIVE
To study the chemical constituents isolated from the roots of Delphinium grandiflorum L. var. leiocarpum W. T. Wang.


METHODS
The constituents were isolated and purified by various chromatographic methods and their structures were identified by spectral analysis.


RESULTS
Five known diterpenoid alkaloids lycoctonine (I), methyllycaconitine (II), delsemine A (III), delavaine A (IV) , delajadine (V) and the other two beta-sitosterol (VI), plamitic acid (VII) were isolated from the roots of Delphinium grandiflorum.


CONCLUSIONS
All these compounds are isolated from this plant for the first time.
