Background: Seidlitzia rosmarinus which is commonly called “Oshnan” or “Eshnan” in Persian belongs to Chenopodiaceae family. Conventionally, it is believed that this plant is toxic. This study was aimed to evaluate the cytotoxic effect of S. rosmarinus against HeLa and HepG2 cell lines. Materials and Methods: S. rosmarinus was collected from the desert near Yazd, Iran. Hexane, chloroform, chloroform/methanol (9:1), and butanol extracts of aerial parts of S. rosmarinus were prepared. Doxorubicin and dimethyl sulfoxide 10% were used as positive and negative control, respectively. The cytotoxic activity was measured using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Results: All extracts significantly and concentration dependently reduced viability of HeLa and HepG2 cells. Hexane, chloroform, and butanol extracts at doses of 200, 500, 750, and 1000 μg/ml significantly reduced HeLa cell viability (P < 0.05). Chloroform/methanol extract at doses of 100–500 μg/ml significantly reduced HeLa cell viability (P < 0.05). Hexane, chloroform, and butanol extracts at doses of 500, 750, and 1000 μg/ml significantly reduced HepG2 cell viability (P < 0.05). Chloroform/methanol extract at doses of 200, 300, 400, and 500 μg/ml significantly reduced HepG cell viability (P < 0.05). The most cytotoxic extract was chloroform/methanol extract in both cell lines. Furthermore, in the both cell lines, the second potent extract was chloroform extract. Conclusions: It can be concluded from the findings of this study that S. rosmarinus is a good candidate for further study to find new cytotoxic agents. Phytochemical investigation on chloroform/methanol extract and their structures is recommended.
