Chloroform, ethyl acetate and methanolic extracts from leaves and stem bark of Buddleja salviifolia were prepared. The phytochemical profiles, total flavonoid contents (TFC), total phenolic contents (TPC) and ferric reducing power of these extracts were studied. The presence of alkaloids, tannins, phlobatannins, saponins, sterols, flavonoids, coumarins, phenolics, terpenoids, quinones and reducing sugars were identified from these extracts. The TFC of these extracts was found to be in the range of 11.36±0.98 to 30.76±1.15 mg QE/g DW, respectively. The TPC of these extracts was found to be in the range of 175.00±0.41 to 465.27±2.65 mg GAE/g DW, respectively. Additionally, these extracts showed a weak to moderate ferric reducing power compared to ascorbic acid. B. salviifolia finds therapeutic applications in traditional medicine. Further studies are required to commercialize products from this plant.
