Abstract

Delonix regia, belongs to family leguminosae, a well-known plant with high medicinal value with antioxidant, hepatoprotective, gastroprotective, wound healing, antiarthritic, larvicidal, antimalarial, antiemetic, antibacterial, antifungal, antiinflammatory, analgesic, antidiarrhoeal, antiheamolytic, diuretic, and anthelmintic activities. The aim of the present investigation was Preliminary Phytochemical screening and antimicrobial activity of Delonix regia (Bojer Ex Hook) extractDelonix regia extract. The ethanolic extract of the leaves of Delonix regia was prepared and carried out for phytochemical constituents using standard methods. Antimicrobial activity of ethanolic extract were carried out against Staphylococcus aureus and Klebsiella. The testing was done by the disc diffusion method. Phytochemical analyses revealed the presence of alkaloids, flavonoids, phenol, terpenes. The in-vitro anti-microbial activity of the ethanolic extract of the plant showed results against the test organisms.
