## Occurrence

Veatchine is found in the bark of Garrya veatchii, a member of the Cup Catkins family.[2] Aconitine is the main alkaloid in aconite.[3]

## 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.[1]

## Representatives

### Diterpene group

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

* Atisine

* Veatchin

### Northern iterpene group

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

* (+)-Lycoctonine

## Properties

Aconitine has cardiac arrhythmic and antipyretic properties and is one of the most toxic plant compounds.[2]
