Abstract
In this paper, human umbilical vein endothelial cells (HUVEC) hypoxic injury models were established by sodium dithionite (Na2S2O4). With the protective effects of total salvianolic acids components (TSAC) against oxidative damage of HUVEC as a starting point, cellviability was measured by MTT colorimetric method； intracellular superoxide dismutase (SOD) activity, malondialdehyde (MDA), lactatedehydrogenase (LDH) level, nitric oxide (NO) level, interleukin6 (IL-6), and human tumor necrosis factor α (TNF-α) expression were measured by kits, to investigate the effect of seven kinds of phenolic acids of TSAC on Na2S2O4-induced HUVEC hypoxic injury. Based on the "component structure" theory, the contribution of the main components in TSAC for the protective effect on hypoxic injury of HUVEC was studied. The results showed that salvianolic acid B, posrnarinic acid A, salvianolic acid A, lactic acid, and lithospermic acid in TSAC play a larger role in protective effect of hypoxic injury of HUVEC. These five components were administered in combinations respectively, and it was concluded that the four components including salvianolic acid B, posrnarinic acid A, salvianolic acid A, lactic acid could be used as the representative components of TSAC.
