Quassinoids, the bitter principles isolated from the Simarubaceous plants, are C-20 oxygenated compounds. Some quassinoids have shown promising anti-cancer, antiviral, antimalarial, amoebicidal, antileikaemic and antifeedant properties. About 300 quassinoids have been reported in the literature. A comprehensive list of quassinoids containing structural formulae, physical constants, derivatives, and natural sources are presented to compare the data of the newly isolated compounds with the reported ones
