Diterpene alkaloids



Diterpene alkaloids are natural products of the terpene alkaloid type.

Occurrence
Veatchine is found in the bark of Garrya veatchii, a member of the Cup Catkins family. Aconitine is the main alkaloid in aconite.

Structure
Diterpene alkaloids can be divided into two groups: The diterpene alkaloids, characterized by a C20 parent body, and the norditerpene alkaloids, which are based on a hexacyclic C19 parent body.

Diterpene group
Among the C20 alkaloids is the atisine-type (atisine, hetidine, hetisine) and the veatchine-type (Veatchin, Napellin).

Northern iterpene group
The C19 alkaloids include, among others, the aconitine type (aconitine, delphinine) and the lycoctonine type (Lycoctonin, Browniin).

Properties
Aconitine has cardiac arrhythmic and antipyretic properties and is one of the most toxic plant compounds.
