Capillin is a toxic naturally occurring organic compound with the chemical formula C
₁₂H
₈O. The structure contains acetophenone and a polyyne (pentadiynyl) portion, conjugated together as an ynone.

Chemical taxonomy

Capillin is found in the essential oil of a number of Artemisia species, including Artemisia monosperma and Artemisia dracunculus (tarragon).^[2] The substance was initially isolated from Artemisia capillaris in 1956.^[3]

Applications

Capillin is a biologically active substance. It has strong antifungal activity, and it is possibly antitumoral. Capillin exhibits cytotoxic activity and could cause apoptosis of certain human tumor cells.^[4]
