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