The quassin, whose term in the official IUPAC nomenclature is: (3aR, 3a1S, 6aR, 7aS, 8S, 11aS, 11bS) -2,10-Dimethoxy-3,3a1,8,11a-tetramethyl-3a, 3a1,6a, 7,7a, 8,11a, 11b-octahydrophenantro [10,1-bc] pyran-1,5,11 (4H) -trione is an organic substance synthesized within quassia (Quassia amara L.) and other plants .
Quassin is also known by the names of: (+) – Quassin or Nigakilactone D and has a brute or molecular formula: C22H28O6 and is a triterpene lactone.
Physically it is a bitter and crystalline white substance and is the precursor of the quassinoid family. It is one of the most bitter substances found in nature with a perception threshold of 0.08 ppm and is 50 times more bitter than quinine.
Quassin can be naturally extracted from some plants, including the quassia tree.
This substance was first isolated in 1937 and its chemical structure was elucidated only in 1961.
Quassia amara tree extracts, containing quassin, are used as additives in soft drinks.
