Quassinoids are degraded triterpene lactones (similar to limonoids) of the Simaroubaceae plant family grouped into C-18, C-19, C-20, C-22 and C-25 types.[1] The prototypical member of the group, quassin, was first described in the 19th century from plants of the genus Quassia from which it gets its name.[2] It was isolated in 1937,[3] and its structure elucidated in 1961.[4]
