Increasing concentration of ethyl acetate and methanol extracts of Chenopodium album (leaves) leads to decreased cell proliferation and enhanced cell toxicity on MCF-7 (breast adenocarcinoma estrogen receptor positive) cell line. Cells were seeded in tissue culture petri plates and treated with plant extracts. MeOH extract exhibited significant antiproliferative activity and showing maximum 87.43% inhibition against cell line MCF-7 at the concentration 100 mg/ml at 24 h. Results represent mean value of triplicate culture with SD. Students' unpaired t-test *p < 0.05 vs. ethyl acetate extract.
