Chamazulene is an aromatic chemical compound with the molecular formula C14H16 found in a variety of plants including in chamomile (Matricaria chamomilla), wormwood (Artemisia absinthium), and yarrow (Achillea millefolium).[1] It is a blue-violet derivative of azulene formed from sesquiterpene matricin after the loss of acetate, water and carbon dioxide during the steam distillation of chamomile blossoms.[2][3] Oral ingestion of matricin results in chamazulene being found in blood plasma and artificial gastric fluid is able to convert matricin to chamazulene.[4]

Degradation of matricin (1) to chamazulene (3) via chamazulene carboxylic acid (2).

Chamazulene has anti-inflammatory properties in vivo and inhibits the CYP1A2 enzyme,[2] but not CYP1A1.[4]
