Green synthesis of plant syzygium cumini used as traditional medicine to cure diabetics was given focus’s of attention. In the present study, syzygium cumini was collected and crude extract was prepared using Soxhlet apparatus and tested for its active principles by Phytochemical analysis. The presence of phenolic compounds flavonoids, saponins, glycosides, proteins, carbohydrate, steroids, threnodies, alkaloids, was recorded. The present study of biosynthesis of MgO nanoparticles treated by syzygium cumini demonstrated which illustrate a characteristic peaks with 9.5, 5.5, & 77.5 observed in the X- ray diffraction image. The X-RD paten showed 3 distinct diffraction peaks corresponding to the diffraction from 111,111, & 202 flaming of arbic spare centered magnesium oxide which are in good agreement with JCPDS (Joint Committee on Powder Diffraction Samples) card no:- 80-1916. The Fourier transform infrared spectroscopy (FTIR) reveled prominent peaks which indicated functional group changes with a band value of 3268.52cm- indicates OH- stretching. Another peak at wave length 1649cm-1 correspond to C=O stretching, and 2926cm- exhibited presence of alkenes groups. FTIR study show syzygium cumini seed reveal presence of pheromones, and S=O group (sulphur), respectively. In order evaluate antimicrobial activity in the plant extract syzygium cumini, two bacterial pathogens such as Staphylococcus aureus, Shigella Flexneri, were studied. Staphylococcus aureus revealed 23mm of inhibition with plant extract as green synthesis where the chemical synthesis to determine antimicrobial activity exhibited 21mm zone of inhibition. The study further extended to assess green synthesis with clinical bacterial Shigella flexneri and staphylococcus aureus found to exhibited zone of inhibition.
