Abstract: Four limonoids, humilinolide E (1) , methyl 2-hydroxy-3 b -tigloyloxy-1-oxomeliac-8(30)-enate (2), swietenine acetate (3) and methyl angolensate (4) were isolated from the fruits of Guarea kunthiana. Compounds 1-3 are being reported for the first time in the genus Guarea, while 4 has been previously described in only one species of this genus. The isolated compounds were identified by spectral methods (1D-, 2D-NMR and EIMS).
