Absinthin is the main component of the bitter substances contained in wormwood ( Artemisia absinthium ) with a content of 0.2 to 0.28% .

Wormwood ( Artemisia absinthium ), inflorescence

Chemically speaking, it belongs to the sesquiterpene lactones , more precisely to the guajanolides - it is formed from two molecules of Artabsin, which is also found in the herb (approx. 0.1%), according to the mechanism of a [4 + 2] cycloaddition ( Diels -Alder reaction ).

Absinthin is more bitter than its precursor Artabsin (ratio of bitter values = 25.4: 1) and makes up about 99% of the bitter value of wormwood ( Absinthii herba ). It is involved in the appetite-increasing, digestive, flatulence and gall flow stimulating effects of wormwood. Absinthin is also used to flavor alcoholic beverages.
