The effects of cytotoxicity of Astragalus cystosus on the Hela Cells by using MTT Method

Abstract Cancer prevention and treatment by medicinal plants for a long was is one of the most challenging areas of research. Among them، some plants species could suppress or kill tumor cells via apoptosis or necrosis. One of these plants is Astragalus. The purpose of this study was investigating the anti-cancer effects of this plant. The cancer cell lines obtained from Pasteur Institute of Iran. The cells were cultured in RPMI 1640. Then the cells have effected from the presence of various concentrations (0. 156، 0. 312، 0. 625، 1. 25، 2. 5، 5، 7. 5 and 10 mg/ml) of Astragalus cystosus. After 72 hours the rate of cytotoxicity was determined by using MTT test. These statistical analyses carried out with a significant level of 0. 05 and t-test with excel software. These findings indicate that the extract of Astragalus cystosus on Hela cancer cell lines had cytotoxicity in all concentrations and the highest inhibition was 7. 5 and 10 mg/ml concentrations. The rate of inhibition in higher concentrations such as 10mg/m1 was equal to 28. 98% which is the highest one. Regarding that the extract of Astragalus cystosus had cytotoxicity on hela cancer cells، further studies can be performed on animal model and clinical trial so that Astragalus used as an anticancer drug.
