ABSTRACT
Comparative antioxidant studies were carried out for methanolic extract of Cassia auriculata flowers, leaves and roots for proving its utility in inflammation and healing mechanism. The methanolic extracts were screened for antioxidant activity by nitric oxide radical scavenging, lipid peroxidation inhibition and DPPH methods at different concentrations. Throughout the studies flowers extract showed marked antioxidant activity compared to leaves and roots extract. The antioxidant activity of the flower flowers extract may be due to stabilization of plasma membrane, thereby lowering the elevated levels of serum lysosomal enzymes. The antioxidant activity was found to be concentration dependent and may be attributed to the presence of high flavanoids and bioflavonoids content in the flowers of Cassia auriculata.
