Abstract
Free radicals cause many diseases in human. Antioxidants reduce the risk of cardiovascular disease and stroke by neutralizing free radicals and on the other hand, prevent progression of cancer. The natural antioxidant enhances antioxidant properties of plasma to prevent diseases such as heart disease, cancer, and stroke. Plants are a rich source of secondary compounds, which are the most important natural antioxidants.
In this study, Fumaria vaillanti aqueous, methanol and ethanol extracts were used to determine the anticancer effect of extracts on Breast Cancer Cells Lines BT-474, MDA-MB_231 after 24, 48 and 72h.
The highest percentage of cell death, according to the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) technique, has been reported in the aqueous extract on MDA-MB-231 cells after 72 hours at with IC50 of 2 μg / ml.
The results of this study indicate that Fumaria vaillanti shows a significant antioxidant and cell toxicity effect and full potential of extracts can be realized by further studies on animal models and subsequent trials.

Abstract
Ovarian cancer is one of the deadliest cancers in women causing abnormal cancerous cells that can spread and metastasize to other parts of the body. Secondary metabolites are highly variable in terms of structural and chemical properties and they are very important for plants survival. In this study, the extracts of two plants using three different solvents (water, ethanol 80% and methanol 80%) and water bath extraction method were obtained. phenolic compounds of extracts were determined by Folin Sioculto method. DPPH (2, 2-Diphenyl-1-picrylhydrazyl) and FRAP (Ferric reducing ability of plasma) methods were performed for determination of antioxidant properties. The amount of phenolic compounds in two plants was higher in 80% methanol solvent and the most antioxidant activities were observed in water solvent of extracts. Water solvent had the highest antioxidant activity and was selected to investigate the anti-cancer properties of extracts on ovarian cancer cells. Water extract of Ocimum basilicum within72 hours had the highest cytotoxic effect with an IC50 value of 1.105 ± 0.001 mg / ml. In study of antimicrobial activity by disc diffusion method, the highest antibacterial properties were only in ethanol extracts of two plants. In the measurement of MIC and MBC, ethanol and methanol extracts of Ocimum basilicum and water and ethanol extracts in Imatiens walleriana had the most inhibitory and bactericide effects.
