C-diterpene alkaloids from lipsky.

The genus is a rich source of diterpene alkaloids. Chemical investigation on an alkaloid rich extract of the whole parts of resulted in the isolation of three C-diterpene alkaloids () and a palmitic acid derivative (). The chemical structures were elucidated by analysis of 1D and 2D-NMR and comparison the data with those reported in the literature. Notably, all isolated compounds were reported for the first time from
