A new limonoid was isolated from the bark of Khaya senegalensis and identified as 2,6-dihydroxyfissinolide. The assignments of some signals in the 13C NMR spectrum of fissinolide have been reversed and the signals of the 1H NMR spectrum of methyl 3β-acetoxy-6-hydroxy-1-oxomeliac-14-enoate have been assigned. The limonoids only showed moderate antiprotozoal activities.
