In the last few decades, research has been focused on the use of natural products for cancer therapy, such as crude plant extracts or some of different plant secondary metabolits. The objective of this study was to examine the invitro cytotoxic activities of crude ethanolic extract of leaf and flower buds of Crataegus melanocarpa, on human MCF-7 and HeLa cell lines, with different concentrations, by Dye exclusion and Micro culture tetrazolium test (MTT) assay. The optical density (OD) colored solution was quantified at 570 nm wavelengths by an ELISA Reader, after 24, 48 and 72 h incubation. The results showed that ethanolic extracts, after 48h incubation, at in 5 and 10 mg/ml suppressed the proliferation of cancerous MCF-7 cells by significant diffrence with control group (p

Background and objective: Chalcones are belonged to an important group of flavonoids which has proven anti-inflammatory and antineoplastic effects. Assessing cellular Cytotoxicity effect of new synthetic chalcone on HeLa cell line is the aim of present study. Materials and Methods: In this experimental in vitro study, HeLa cells were treated with various concentrations of chalcone for 72 hours and cell death rates was evaluated by MTT test. Results were analyzed by Student T-Test and morphological changes were assessed by Acridine orange and propidium iodide (PI) staining. Results: Our results showed that new synthetic chalcone in studied concentrations inhibited tumor cell growth. Highest percent (50.44%) of growth inhibition was seen in 40 µg/ml concentration and after 72 hours IC50 was 40µg/ml. morphological changes of HeLa cells after 24 hours were also strengthened the probability of cellular apoptosis. Conclusion: The results showed that new chalcone has inhibitive effects on HeLa tumor cell line and a probable mechanism of apoptosis can causes cellular death.

Abstract
Background & objectives: 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.
Material & method: 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.
Findings: 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.
Conclusion: 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.
