<br/><br/> The present study was undertaken to isolate and identify of chemical  constituents of two Caesalpinia species by chromatographic methods and to  determine antimicrobial, antioxidant and cytotoxic activities of the extracts  of this ayurvedic plant. Antimicrobial activity was tested against  Staphylococcus aureus (G+ve bacteria), Pseudomonas aeruginosa (G-ve  bacteria), Candida albicans (yeast) and Aspergillus Niger (Fungi) by Disc  agar plate method. Antioxidant activity was determined by DPPH free  radical scavenging assay, ferric reducing assay and total antioxidant capacity.  Cytotoxic activity was evaluated via using preliminary brine shrimp lethality  test and toward liver cancer cell line; HepG2. The results of the biological  activities showed promising activities for some of the isolated compounds
