Scorzoneroides
''Scorzoneroides'' or hawkbits is a genus of plants of the tribe Cichorieae within the family Asteraceae. ''Scorzoneroides'' used to be included in the genus ''Leontodon''. Recent molecular studies revealed that ''Leontodon'' in the older, broader sense is an unnatural adhesion of two separate groupings. Therefore, the former subgenus ''Oporinia'' of the genus ''Leontodon'' had to be resurrected as a separate genus. Secondary metabolites In some members of the genus ''Scorzoneroides'', germacranolides and costus lactone-type guaianolides were detected. The genus is a rich source of hieracin-type and lactucin-type guaianolides. Phenolics found in flowering heads of ''Scorzoneroides'' taxa include luteolin type flavonoids and caffeoyl quinic acid derivatives such as chlorogenic acid and 3,5-dicaffeoylquinic acid. Moreover, ''Scorzoneroides'' are source species of caffeoyl tartaric acid Caftaric acid is a non-flavonoid phenolic compound. It is found in the juice of grapes ('' ...
