Maslinic acid (MA) and oleanolic acid (OA), the main triterpenic acids present in
olive, have important properties for health and disease prevention. MA selectively inhibits
cell proliferation of the HT29 human colon-cancer cell line by inducing selective apoptosis.
For measuring the MA and OA concentration inside the cell and in the culture medium, a
new HPLC-MS procedure has been developed. With this method, a determination of the
amount of MA and OA incorporated into HT29 and HepG2 human cancer-cell lines
incubated with different concentrations of MA corresponding to 50% growth inhibitory
concentration (IC50), IC50/2, IC50/4, and IC50/8 has been made. The results demonstrate that
this method is appropriate for determining the MA and OA concentration in different types
of cultured cells and reveals the specific dynamics of entry of MA into HT29 and HepG2 cells.
