Matricaria discoidea (C.suaveolens) flowers contained 0.12% essential oil. (Z)-en-yne-dicycloether (37%), geranyl isovalerate (22%), and (E)-β-farnesene (15%) are the main components. Chamazulene is the typical constituent of the essential oil of Chamomila recutita ([[matricaria_chamomilla_l|Matricaria chamomilla]]), but was found in Matricaria discoidea at only 0.5%. \\
