anti-tumor activity of ferulago angulata boiss. extract in gastric cancer cell line via induction of apoptosis

abstractferulago angulata boiss. known in iran as chavir, has some bioactive compounds having antioxidant activity. because of its antioxidant activities, it sounded chavir extract can be a good candidate for finding chemopreventive agents having inductive apoptosis properties on cancer cells. in this study, the cytotoxic effects and proapoptotic activities of chavir’s leaf and flower extracts were investigated on human adenocarcinoma gastric cell line (ags). the ferric reducing antioxidant power (frap) assay was used to determine antioxidant activity of the extract. cytotoxic effects of the extract were performed by trypan blue and neutral red assays. for apoptosis detection, we used annexin v staining, flow cytometry and dna fragmentation assays. the frap assay results showed that antioxidant activity of leaf extract was higher than flower extract. cytotoxicity and apoptosis–inducing activity of flower and leaf extracts changed coordinately, indicating the cytotoxicity of chavir extracts is due probably to induce apoptosis. our results revealed that the cytotoxic effects of f. angulate boiss. extracts on ags cell line is close to some other plant extracts such as rhus verniciflua stokes (rvs) and scutellaria litwinowii. this is the first study on cytotoxic and apoptosis–inducing effects of chavir leaf and flower extracts against ags cell line. the further investigation can be identification of the agent(s) by which these effects is observed.
