Eugenia jambolana family myrtaceae is a large deciduous tree, originally from India. The pulps of the fruit are pH sensitive and give different colors in acidic condition (pink) and basic condition (greenish yellow). The present work highlights the use of Eugenia jambolana fruit extract as an acid base indicator in different types of acid base titrations. The equivalence points obtained by the fruit extract matched with the equivalence points obtained by standard indicators. Therefore, this natural indicator is found to be a very useful, economical, simple and accurate for acid base titration.
