  The aim of this study was to investigate the antiangiogenic effect of the Nigella sativa seeds extracts. Twelve extracts were prepared from the N. sativa seeds by supper critical carbon dioxide by varying extraction pressure and temperature. GC-MS analysis revealed the presence of 22 compounds, mainly thymoquinone (TQ), thymohydroquinone and androstane-3,17-diol. The extracts showed significant antioxidant activity, and cell viability study on human umbilical vein endothelial cells (HUVECs) indicated that two extracts (A3 and B3), prepared at higher temperature (60°C) and the lower pressures (2500 and 3000 psi), were the most potent anti-proliferative extracts; the median inhibitory concentrations were 41.5 ± 1.9 and 60.2 ± 2.2 μg/mL, respectively. The extracts down-regulated the expression of vascular endothelial growth factor (VEGF) in endothelia cells causing i.. View More»
