A new triterpene ester (1) together with eight known compounds (2–9) were isolated from the leaves of Cadaba farinosa Forssk. Their chemical structures were established on the basis of physical, chemical, and spectroscopic methods (IR, 1D and 2D NMR, and mass spectral analyses) to be: lupeol-3-O-decanoate (1), lupeol (2), -sitosterol (3), ursolic acid (4), 12-aminododecanoic (5), dillenetin-3-O--D-glucopyranoside (6), stachydrine (7), 3-hydroxy-stachydrine (8), and quercetin-3-O--D-glucopyranoside (9). That is the first report for the isolation of compound 5 from a plant source. Compounds 5, 6, and 9 were evaluated for their antioxidant activity.
