Safflower (Carthamus tinctorius Linn.) Inhibits Cell Proliferation and Induces Apoptotic in Breast Cancer Cell Lines T47D.

<b>Background and Objective:</b> Safflower (<i>Carthamus tinctorius</i> Linn.) is one of the medicinal plants that contain secondary metabolites that have the potential to as anti-cancer by inducing apoptosis. This study aims to determine the content of secondary metabolite compounds and the induction activity of apoptosis from ethanol extract of safflower in the T47D breast cancer cell line. <b>Materials and Methods:</b> Safflower was extracted using 96% ethanol and assayed for phytochemical screening, cytotoxic tests by cell counting kit-8 to determine inhibitory concentration and apoptosis induction activity by flow cytometry to determine the ability of samples induce the programmed cell cancer in death. The data collected was analyzed with the PRISM GraphPad version. <b>Results:</b> The ethanol extract of safflower contains flavonoid compounds, alkaloids, saponins, tannins and terpenoids. The results of the anticancer activity test showed an IC₅₀ value of 479 μg mL¹ and the best percentage of apoptosis at a concentration of 200 μg mL¹ was 16.61% at the beginning of apoptosis and 10.52% at the end of apoptosis. <b>Conclusion:</b> The safflower can be developed as a breast anticancer agent that works through the induction of apoptosis to improve the effectiveness of breast cancer treatment.
