Matricin is a colorless, crystalline active ingredient from the single flowers of the real chamomile , which contains up to 0.15%. It was isolated for the first time in 1957 and its constitution was determined.

Chamomile inflorescences ( Matricaria chamomilla ) contain matricin.

The suspected structure as sesquiterpene lactone was confirmed in 1982 by NMR measurements. Matricin acts as chamazulene , in which it is in steam distillation with elimination of acetic acid , water and CO 2 converts, antiphlogistic .

Formation of chamazulene

During the steam distillation, the Matricin ( 1 ) first splits off a molecule of acetic acid and water; the chamazulene carboxylic acid is formed ( 2 ). On further heating, this is decarboxylated to chamazulene ( 3 ) :

Production of chamazulene ( 3 ) from matricin ( 1 ) via chamazulene carboxylic acid ( 2 ).

While the starting material matricin is colorless, the chamazulene carboxylic acid and the end product chamazulene have a deep, blue-violet color.
