A phytochemical investigation of the Tunisian plant Acacia cyclops pods led to the isolation of two new monoterpenoid glycosides, which have been designated Cyclopside 1 and Cyclopside 2. Their structures were elucidated on the basis of extensive spectroscopic procedures including IR, MS and 2D-NMR. The cytotoxic effect of the isolates was also evaluated in vitro against the human breast cancer (MCF-7) and ovarian cancer (OVAR) cell lines. Results showed that the highest cytotoxic activity (90.88%) was against MCF-7 cell line and was exhibited by the Cyclopside 1 at the concentration of 50 μg/mL.
