Abstract: Starfruit botanically known as Averrhoa carambola and it belongs to family Oxalidaceae, grows in tropical and subtropical regions throughout the world. The Starfruit can be used raw as vegetable and ripe as fruit. The Starfruit are sweet tasting fruit that possesses high nutritional value. This study was aimed to understand the antimicrobial, antioxidant activities and nutritional content of tropical fruits Averrhoa carambola (starfruit). The edible parts of the fruits were analyzed for different phytochemicals and antioxidant activity like phenolics, flavonoids, DPPH, and ascorbic acid were found in starfruits. In the present study, information regarding the extracts of Averrhoa carambola were evaluated to investigate antimicrobial activity against Gram positive and Gram negative bacteria by well diffusion method. Phytochemical were present such as saponins, phenols, tannins, steroids, proteins, carbohydrates and flavonoids as well as measured nutrients content like proteins, carbohydrates, vitamins, minerals. In this study well defined silver nanoparticles were synthesized by using carambola fruit extract. The synthesized NPs were analyzed by ultraviolet spectroscopy. The antimicrobial activity of the synthesized AgNPs was obtained against Escherichia coli and Pseudomonas aeruginosa by agar well diffusion method.
