Araucaria cookii, Bauhinia blakeana and Brassaia actinophylla are ornamental plants. The presence of various phytochemicals and pharmacologically important compounds in these plants can be exploited for their medicinal use. But there are no reports on the phytochemical and pharmacological evaluation of these plants and this study aims at investigating these. The plant extracts were prepared in different solvents like methanol, ethanol, ethyl acetate, acetone, hexane, water and chloroform. Qualitative analysis of phytochemicals were assessed. The anti-microbial, anti-oxidant and enzyme inhibitory activity was determined for all three plant extracts. Anti-bacterial activity against three gram negative bacteria, E. coli, Pseudomonas and Klebsiella was done and Araucaria cooki showed highest antibacterial activity among the three plants. Maximum antioxidant activity was seen in methanol extract of Brassaia actinophyla with 81% inhibition. The order of the antioxidant activity of the three plants are in the order B.actinophylla>A cookie>B.blakeana. The results of phytochemical analysis suggest that phytosteroids are present in all the three plants. Maximum inhibition against the tested enzymes was exhibited by hexane and chloroform extracts of A.cookii. Hemolytic activity was done and the hexane extract showed maximum haemolysis where as aqueous extracts showed minimum activity. From the results it is clear that the three plant extracts has pharmacological applications. This is the first report of antimicrobial, antioxidant and enzyme inhibitory activities of these three plant extracts. Further studies are needed to exploit the actual mechanism and active compounds of these plants.
