Abstract: Herbal medicine has been in use by diverse civilizations in different parts of the world for centuries. Present study investigates the phytochemical constitution of the methanolic extract of the aerial part of Plectranthus hadiensis (Forssk.) Schweinf. ex Spreng. The preliminary phytochemical screening of the methanolic extract had revealed high content of phenolics which was confirmed by TLC, HPTLC and HPLC studies. The antioxidant activity was checked using DPPH assay, nitric oxide radical scavenging activity assay and reducing power assay. The methanolic extract showed considerably high antioxidant activity compared to the standards used, viz. ascorbic acid and BHT (Butylated Hydroxy Toluene). The presence of phenolics supported medicinal uses of the species and active biomolecules could be isolated for pharmaceutical applications.
