Secondary metabolites
The genus ''Leontodon'' s.str. (i.e. excluding the members of the resurrected genus ''Scorzoneroides'') is a rich source of hypocretenolides, unique guaiane type sesquiterpene lactones with a 12,5-lactone ring instead of the usual 12,6 lactone ring.
Phenolics found in ''Leontodon'' include luteolin type flavonoids and caffeoyl quinic acid derivatives such as chlorogenic acid and 3,5-dicaffeoylquinic acid. Moreover, ''Leontodon'' species contain the caffeoyl tartaric acid derivatives caffeoyl tartaric acid and cichoric acid.
