Norditerpene alkaloids from Delphinium linearilobum and antioxidant activity
From the roots of Delphinium linearilobum (Trautv.) N. Busch two new norditerpene
alkaloids linearilobin and linearilin, and the known alkaloids lycoctonine, 14-
acetyltalatizamine, browniine, cammaconine, talatizamine, and cochlearenine were isolated.
Spectroscopic techniques were used for structure determination. Antioxidant activity was
performed by DPPH and metal chelating activity assays.
