Antioxidant activity of Matthiola incana flowers extracted with different solvents like petrolewn ether, chloroform, ethyl acetate, absolute methanol, methanol water (9.5:0.5) methanol water (9:1) extracts of stock flower (Matthiola incana) were analyzed. The total phenolics content (TPC) were fOWld in the range of 0.321–1.812 mg GAF/g and total f1avonoids content (TFC) were found in the range 2.06–6.061 CEmg/g. Other parameters studied were reducing power, DPP Hradical scavenging and inhibition of linoleic add per oxidation. The antioxidant activity of the Matthiola incana was also evaluated by measuring the conjugated dienes (CD), conjugated triene (CT), p-anisidine value (PAV), free fatty add (FFA) and peroxide values (PV) by using canola oil as an oxidative substrate. The n-hexhane extract was also analyzed by GC-MS. The methanolic extracts of Matthiola incana flowers showed maximum antioxidant activity. The cytotoxidty studies was also studied by haemolytic activity of the plant extracts against the hwnan erythrocytes (RBC's) was found to be in the range of 0.91–4.41%.
