Six hydroxycinnamic acids : caffeic acid, chlorogenic acid, 3,5-O-dicaffeoylquinic acid 2-O-caffeoyltartaric acid (caftaric acid) and 2,3-O-dicaffeoyltartaric acid (chi- coric acid) have been isolated fromLapsana communis L.subsp. communisaerial parts. Among flavonoids, only isoquercitrin, luteolin and luteolin-7-O-β-glucuronide were identified. Except for chlorogenic acid, these com- pounds represent the first report inLapsana communis.

Chicoric acid is the major phenylpropanoic constituent in this plant.
