Quassinoids

ABSTRACT

Quassinoids, the bitter principles isolated from the Simaroubaceous plants, are C-20 oxygenated compounds. Some quassinoids have shown promising antitumour, antiviral, antimalarial, amoebicidal, antileikaemic and antifeedant properties. About 100 quassinoids have been reported in the literature. A comprehensive list of quassinoids containing structural formulae, physical constants, UV, IR, 1H NMR, 13C NMR, EI mass spectral data, semi-synthetic analogues and natural sources have been presented to compare the data of the newly isolated compounds with the reported ones
