The plant Plectranthus amboinicus (Lour.) Spreng belongs to family Lamiaceae, known as country borage in English. The anti-oxidant potential of aqueous and ethanolic extract of leaves of Plectranthus amboinicus (Lour) Spreng was investigated by DPPH assay, reducing power assay and nitric acid screening methods. The preliminary phytochemical analysis showed presence of alkaloids, carbohydrates, glycosides, proteins, amino acids, flavonoids, quinine, tannins, phenolic compounds and terpenoids. The total phenolic content is also evaluated as they contribute in anti-oxidant property. The anti-oxidant potential and reducing power of both extracts increased with increasing concentration of extract (50 g â?? 250 g). Phenolic contents of ethanolic and aqueous extracts were found 11.6 ?¼g and 9.4 ?¼g gallic acid equivalent per mg of extracts respectively. This study is to verify the anti-oxidant potential and to evaluate total phenolic contents in Plectranthus amboinicus (Lour.) Spreng leaves.
