The objective of the study was to analyze the anticancer property of the leaves of Triticum aestivum on HeLa cells. The Indian medicinal plant Triticum aestivum that is used in traditional medicine for cancer and non cancerous diseases was collected. The crude methanolic extract was prepared by using standard protocols. The antiproliferative effect the methanolic extract was evaluated in vitro by employing MTT assay. The potency of each plant extract concentration was calculated in terms of percent decrease in viable HeLa cells as compared to the control value. The extract showed dose dependent antitumor activity. The MTT assay showed an anti proliferative activity (IC50) at 156 μg/ml of crude extract.
