The leaves and the fruits from Syzygium jambolanum DC. (Myrtaceae), a plant known in Brazil as sweet olive or 'jambolan', have been used by native people to treat infectious diseases, diabetes, and stomachache. This study aimed to determine the conductivity in different samples of a freeze-dried aqueous extract of Syzygium jambolanum in different periods of time. The readings of the electrical voltages of the samples subjected to different treatment conditions were carried out in a pH meter. Depending on the performed statistical analysis could be noticed a significant difference (p <0.005) among all samples analyzed groups. From the analysis of the results we can speculate that the aqueous extract of Syzygium jambolanum study has in its constitution phyto molecules which exhibit significant volatility as a function of time with antioxidant potential is sensitive to the presence of oxygen and exposure to light.
Keywords: Syzygium jambolanum, Anthocyanin, Flavonoids, Antioxidant, Plant extract.
