Diterpene alkaloids

[1] Veatchine is found in the bark of Garrya veatchii, a member of the Cup Catkins family.

[3] 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.

[1] Among the C20 alkaloids is the atisine-type (atisine, hetidine, hetisine) and the veatchine-type (Veatchin, Napellin).

[1] The C19 alkaloids include, among others, the aconitine type (aconitine, delphinine) and the lycoctonine type (Lycoctonin, Browniin).

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