The aim of our present study was to evaluate the antioxidant and anti-lipid peroxidation activity of ethanolic extracts of Bougainvillea species viz B. shubhra, B. peruviana and B. bhuttiana golden glow. Phytochemical constituents viz. total phenolics, flavonoids and tannins were assayed using standard protocol. The antioxidant activity was studied by DPPH assay, FRAP assay, reducing power assay and in-vitro inhibition of lipid peroxidation. Of the three species, B. bhuttiana golden glow showed highest amount of phenols (6.78±0.001), flavonoids (27.7±0.012) and tannin (11.08±0.008) contents. It also showed highest antioxidant activity of 15.15± 0.008 and 8.08± 0.018 as determined by FRAP assay and reducing power assay respectively. The percent DPPH radical scavenging activity was 82.72% and in-vitro inhibition of lipid peroxidation in mitochondrial membrane was also found to be highest in B. bhuttiana golden glow.
