ABSTRACT

Annona muricata is a fruit native of Central America, which has become an important crop because of its tasty flavor, high pulp content, and nutritional value and antioxidant properties. This study was aimed to determine the phytochemicals as well as antioxidants present in the plant and antibacterial activities of various parts of Annona muricata. The aqueous leaf extract contains a high protein and phenol content of 36.66 mg% and 134.28 mg% respectively. The non enzymatic Anti-Oxidant components like Vitamin-C and Vitamin-E of aqueous leaf and seed extract contains 66.6 mg% and 26.68 mg% respectively. The enzymatic anti-oxidant components like Super Oxide Dismutase (SOD) and Catalase of aqueous leaf and seed extract contains 255 U/mg and 83.4µmol of /min/mg respectively. The ethanolic leaf extract shows high phosphorous and iron content of 128 mg% and 1.075 mg% respectively. The ethanolic root extract shows highest calcium content of 22 mg% and the aqueous extract of seed contains high carbohydrate content of 11.025 mg% respectively. The ethanolic extract of leaf shows highest antibacterial activity towards Pseudomonas aeruginosa and Staphylococcus aureus.
