The study was carried out to investigate the phytoconstituents, reducing power and total antioxidant capacity of some common fruits viz. Citrulis vulgaris, Cucumis melo, Cucumis sativus, Malus domestica, Ananas comosus, Musa paradisica, Psidium guajava, solanum melongena and citrus senensis in vitro by spectrophotometric method. The preliminary qualitative phytochemical analysis showed the presence of carbohydrates, proteins, amino acids, steroids, glycosides, flavonoids, tannins, and polyphenols in all the nine methanol fruit extracts. Psidium guajava, Ananas comosus, Citrus senensis, Malus domestica, Solanum melongena revealed the presence of Alkaloid whereas Alkaloid is not detected in the other fruits viz; Citrulis vulgaris, Cucumis melo, Cucumis sativus, Musa paradisiacal. Saponins is detected in Cucumis sativus and Cucumis melo only. The reducing power studies showed Psidium guajava to have the highest activity followed by Malus domestica>Citrus senensis >Solanum melongena>Citrulis vulgaris>Ananas comosus>Cucumis melo>Cucumissativus>Musa paradisiaca. The antioxidant capacity studies showed Citrulis vulgaris to have the highest antioxidant capacity followed by Cucumis melo>Cucumissativus >Psidium guajava>Citrus senensis>Musa paradisiacal > Malus domestica >solanum melongena>Ananas comosus. This study revealed the potentials of these common fruits as natural antioxidants sources.
