Abstract

ItÍ´s well documented that oxidized low density lipoprotein (LDL) plays a major role in the modification of atherosclerosis. Nigella sativa (NS) and Saussurea lappa (SL) in literature documented as a good antioxidant.To undertaken to evaluate the ability of NS and SL for inhibition of LDL oxidation in-vitro, in fact Nigella sativa and Saussurea lappa LDL was collected by ultracentrifugation and enhanced to oxidize by CuSO4 and NS and SL were used to inhibit LDL oxidation in-vitro. Free radical scavenging of 50% of radicals of DPPH and phenolic content of both herbals were measured to assess the antioxidant activity and compared with standard antioxidant (vitamin E). The inhibitory effect of NS, SL and vitamin E against oxidation ratio was significantly better than in non addition of both herbals (p<0.01); NS was better than SL (p<0.01); and comparable with vitamin E. Both herbals possess good antioxidant activity against DPPH radicals and have high phenolic contents enable it to inhibit LDL oxidation in-vitro. NS and SL possess strong antioxidant activity comparable with vitamin E and good for cardiovascular health.

Keywords: Nigella sativa, Saussurea lappa, vitamin E, LDL oxidation, antioxidant activity.
