The effects of Methanolic extract of Costus pictus (CPME) on lipopolysaccharide (LPS)-induced vascular oxidative stress and inflammation in cultured RAW 264.7 macrophages were studied. Treatment of with varying concentration of CPME (1ng to 10µg/ml) did not alter the cell viability indicating that they were not cytotoxic even at the highest concentration tested. CPME showed dose dependent suppression on LPS-induced production of NO with a highest at 10µg/mL. ROS plays a vital role in the reduction of antioxidant potency and increases DNA loss and the underlying reason for many diseases such as cardiovascular, inflammatory, diabetic, neurological, and lipid peroxidation. ROS performs a substantial character in organ injury such as brain and uterus since the uplifted value of ROS is associated with a reduction in the overall antioxidant ability and a notable increase in DNA disruption. In this context, SOD, Peroxidase, GPX and GSH are vital elements of the antioxidant defense system were studied, whose inhibition of this mechanism ends in increased vulnerability to free radical cellular damage. DCF-DA staining substantiated the protective influence of CPME against LPS-induced ROS generation which was confirmed by elevated fluorescence signals in LPS stimulated control unlike the treatment groups. The protective effects were measured using cell viability, a MTT assay and the anti-oxidative activity was determined by measuring reactive oxygen species (ROS) generation, oxidative products and endogenous antioxidant enzyme activities proves CPME to be a potent anti-inflammatory and antioxidant principle containing extract.
