Fig. 3From: Extraction and purification of total flavonoids from pine needles of Cedrus deodara contribute to anti-tumor in vitroAnti-proliferative effects of TFPNCD on hepatocellular carcinoma HepG2 cells. Cells were treated with different doses of TFPNCD (5, 10, 20, 30, 40, 50, 60, 80, 100 μg /mL) for 48 h before the measure of cell proliferation by MTT assay. Data were expressed as mean ± SD deviation values obtained from three independent determinations. **P < 0.01 versus controlsBack to article page
