Matricin

Matricin is a colorless sesquiterpene found in the flowers of chamomille (Matricaria chamomilla).^[1] Steam distillation during the processing of chamomille can convert matricin to chamazulene, a blue-violet derivative of azulene.^[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.^[1]

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