Inhibitory effect of myricetin on the growth of human umbilical vascular endothelial cells (HUVECs). (A) Chemical structure of myricetin. After HUVECs were cultured with myricetin (0.16, 0.8, 4, and 20 μM) for 24 hours, (B) cell viability and (C) cytotoxicity were assessed by the MTT and lactate dehydrogenase release assays, respectively. Results are expressed as the percentage of control cells cultured in the absence of myricetin and reported as the mean ± SD of three separate experiments; *P < 0.05, **P < 0.01 compared with control.
