Scorzonera Explained

Scorzonera is a genus of flowering plants in the tribe Cichorieae within the family Asteraceae.[1] [2]

Species of the genus are found in Europe, Asia,[2] and Africa.[3] Its center of diversity is in the Mediterranean.[4]

Scorzonera is recorded as a food plant for the larva of the nutmeg, a species of moth.

Species

The following species are recognised in the genus Scorzonera:[5]

Etymology

One possible origin of the genus name is the French scorzonère ("viper's grass").[2]

Secondary metabolites

Some Scorzonera species contain lactones, including members of the guaianolide class of sesquiterpene lactones.[6] Flavonoids found in Scorzonera include apigenin, kaempferol, luteolin, and quercetin.[7] Other secondary metabolites reported from the genus include caffeoylquinic acids, coumarins, lignans, stilbenoids, and triterpenoids.[8] One unique class of stilbenoid derivative was first isolated from Scorzonera humilis. They were named the tyrolobibenzyls after Tyrol in the eastern Alps, where the plant was collected.[9]
