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