The fruits of Cipadessa fruticosa Bl. afforded two new limonoids: methyl 8α,30α-epoxide-3β- (2’-methylbutyryloxy)-1-oxomeliacate (cipadesin A) and methyl 21,23-dihydro-23-hydroxy-21-oxo- 3β-tigloyloxy-1-oxomeliac-8(30)-enate (febrifugin A), along with the known limonoids cipadesin, khayasin T, febrifugin, ruageanin A and mexicanolide. Their structures were elucidated on the basis of spectroscopic methods.

Key words: Cipadessa fruticosa, Meliaceae, Limonoid, Cipadesin A, Febrifugin A
