Background: Medicinal plant have various phytochemicals and used for the treatment of different kind of disease. Objectives: To determine the phytochemical, antimicrobial activity and antioxidant analysis of Cocos nucifera (L.) flowers. Materials and Methods: Cocous nucifera flowers were shade dried and extracted with solvents ethanol and water then extract screen for antimicrobial and antioxidant activities. Phytochemical screening such as carbohydrate, alkaloids, steroids, phlobatannins, saponins, tannins, terpenoids, quinines, flavonoids, phenols and glycosides. For antimicrobial studies seven bacterial and two fungal clinical isolates selected for the study. DPPH antioxidant studies also performed based on the phytochemicals present in Cocos nucifera flowers. Results and conclusion: Phytochemical analysis confirmed that ethanol, chloroform and aqueous extracts were showed the presence of carobohydrates, flavonoids, phenols, terpenoids, quinines, sterols and glycosides. The Cocous nucifera flower extract tested seven bacterial clinical isolates and two fungal clinical isolates.4mg of plant sample showed the maximum zone of inhibition. The DPPH assay showed maximum 5 mg of plant extracts having better activity in ethanol, chloroform and ascorbic acid. The results showed that phytochemical constituents present in Cocous nucifera flower extract showed that the potential antimicrobial and antioxidant activities.
