  1. Quassin

    Quassin is a white bitter, crystalline substance extracted from the quassia tree. It is one of the most bitter substances found in nature with a bitter threshold of 0.08 ppm and it is 50 times more bitter than quinine. Quassin is used as a medicine in traditional Chinese medicine. Extracts of the Bitter tree are also used as additives in soft drinks. Although its skeleton possesses 20 carbon atoms, quassin is not a diterpene but rather a triterpene lactone, which derives from euphol by loss of 10 carbon atoms including C4.
