<p>ABSTRACT<br />Objective: This study aims at performing a preliminary phytochemical analysis to evaluate the phytochemical composition of pineapple extract and<br />its cytotoxicity potential on oral cancer cell lines.<br />Methods: Preliminary phytochemical analysis of pineapple extract was done, 3-(4, 5-Dimethyl-2-thiazolyl)-2, 5-diphenyl-2H-tetrazolium bromide<br />assay for evaluating the cytotoxicity potential of the extract on oral cancer cell lines was performed.<br />Results: Phytoconstituents such as flavonoids, coumarins, and phenols were present in the pineapple extract. The extract also exhibited increased<br />cytotoxicity with increased concentration.<br />Conclusion: This study is conducted to see if pineapple extract is effective in treating oral cancer in a natural way instead of harmful treatments.<br />Keywords: Cytotoxicity, Pineapple extract, Anticancer drug.</p><p> </p>
