Consolida ajacis (doubtful knight's spur or rocket larkspur) is an annual flowering plant of the family Ranunculaceae native to Eurasia. It is widespread in other areas, including much of North America, where it is an introduced species. It is frequently grown in gardens as an ornamental for its spikes of blue, pink or white flowers. It may reach a meter in height. Since the aerial parts and seeds of C. ajacis have been found to contain diterpenoid alkaloids (see below), including the highly toxic methyllycaconitine, the plants should be considered as poisonous.
Sowing
In the UK, Consolida ajacis can be sowed under cover between February and April, or directly outdoors between April and May and/or late August and September.[1]
Flowering
In Europe, it flowers between June and October.[2]
Chemical constituents
The first alkaloid to be isolated from C. ajacis seeds was ajaconine, reported by Keller and Volker in 1914.[3] Since that time, over thirty other structurally related diterpenoid alkaloids have been reported; these are:[4]
14-acetylbrowniine
14-acetyldelcosine
14-acetyldelectine
13-O-acetylvakhmatine
ajabicine
ajacine
ajacusine
ajadelphine
ajadelphinine
ajadine
ajadinine
ajanine
ambiguine
anthranoyllycoctonine
browniine
14-deacetylajadine
14-deacetylambiguine
delajacine
delajacirine
delajadine
delcosine
delectine
delphatine
delpheline
delphisine
deltaline
deltatsine
dihydroajaconine
18-methoxygadesine
19-oxoanthranoyllycoctonine
19-oxodelphatine
