Ziziphus jujuba is the most commonly grown fruit in Pakistan, having essential oil that can be utilized for the purposes of preservation like jujuboside and other flavoniides. In Pakistan it is used for the treatment of ulcers, wounds, eye diseases and bronchitis. Antioxidants are naturally occurring or synthetic substances which prevent oxidation or chemical reaction involving oxygen. The main focus of this investigation was to study the chemical constituents, antioxidant activity and phytochemicals present in the Ziziphus jujuba L. The results indicated that different extracts fractions from methanol, n-hexane, ethyl acetate and chloroform ranges from 20 to 100% concentration indicated that noticeable antioxidant properties were present in jujuba species that were determined by spectrophotometric techniques. The maximum antioxidant properties were observed in 100% chloroform and in M3 (60% methanol and 40% chloroform) and minimum were analyzed in E1 (20% ethyl acetate and 80% n-hexane) and M1 (20% methanol and 80% chloroform). The extraction techniques and extracting solvent were of great importance in this study that showed the extractability of various solvent.
