    Aim: In this study, it was aimed to determine the total phenolic content, flavonoid content, and antioxidant activity of Castanea sativa Mill. (chestnut) leaf extract and their anti-proliferative effect on MCF 7 cell line. Materials and Methods: It determined antioxidant capacities by using DPPH assay, total phenolic content by using Folin-Ciocaltaeu method and Total flavonoid content by aluminum chloride colorimetric method in the ethanolic extracts of Chesnut leaf. In addition, the anti-proliferative effect of chestnut leaf extract was determined by XTT method in MCF7 breast cell line. The leaf extract used was applied at different concentrations for 24 hours, 48 hours and 72 hours and the results were evaluated with the Graphpad Prism software program. Results: In this study, it was revealed that the total phenolic contents of ethanolic extracts of chestnut leaf 58,22 mg GAE/g. Total flavonoid content was 64,62 mg QE/g. The DPPH activity of the leaf extract of chestnut was 80.06%. Moreover, findings showed that Chestnut leaf extract had cytotoxic effect against breast cancer cells depends on concentration and time. The 24h, 48h and 72h most effective IC50 dose were 100.1 µL ,193 µL 15.23 µL, respectively. Conclusion: Chestnut has potential antiproliferative and antioxidant activities in conjunction with its high phenolic and flavonoid content on the MCF-7 cell line. However, more studies are needed.

    Objective: Fenugreek paste, which contains fenugreek and some spices, is a widely consumed food in Kayseri and the surrounding region of Turkey. In this study, the antitumor effect of an extract obtained from fenugreek paste was investigated in Balb/C mice bearing Ehrlich ascites tumor (EAT). Materials and Methods: The concentration of fenugreek paste extract in vivo was 200 and 400 mg/kg and in vitro was 250, 500 and 1000 µg/ml. At the end of the experiment, the volume of abdominal ascites fluid was measured and cells were counted.Results: Fenugreek paste extract delayed weight gain due to EAT cell proliferation in the treatment groups and caused a significant decrease in the number of cells in the ascites fluid in the 400 mg/kg fenugreek paste extract group (47.28 × 106) compared to the control group (67.60 × 106; p = 0.041). Histopathological analysis showed that EAT cells intensely adhered to tissues from the control group and adhered less in the treatment groups. The decrease was more significant in the 400-mg/kg fenugreek extract group. After 24-hour culture, there was a significant difference in EAT cells between the control group (5.9 ± 0.2) and the 250-, 500- and 1000-µg/ml fenugreek paste extract treatment groups (5.7 ± 0.2, 5.7 ± 0.2, and 5.6 ± 0.1, respectively; p = 0.013).Conclusion: The study results suggested that fenugreek paste extract had an antitumor effect on EAT cells.
