Phytochemical Screening and Antimicrobial Activity from Sonneratia caseolaris Fruit Extract

摘要

A study out to investigate the phytochemical screening and antimicrobial activity of iSonneratia caseolaris fruit, a mangrove plant from Maros Regency, South Sulawesi, Indonesia. The iSonneratia caseolaris extract was prepared by two different solvent: ethyl acetate and ethanol 70%. We tested the extract of iS ionneratia caseolaris for antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH). The phytochemicals were extracted separately with ethyl acetate and ethanol 70% by maceration. The evaluation of antibacterial activity for different solvent with different concentration of iSonneratia caseolaris fruit was measurements of inhibitory power are measured by measuring the diameter of the clear zone formed. In phytochemical test iSonneratia caseolaris fruits extracted by ethyl acetate solvent confirmed the presence of flavanoids, saponin, tannin and phenolic and extracted by ethanol 70% solvent confirmed the presence of alkaloid, saponin and phenolic. The antioxidant activity as indicated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity of the iSonneratia caseolaris fruits extract from the species was found to be quite appreciable. The antioxidant scavenging activity of iSonneratia caseolaris fruit extract by ethyl acetate solvent was 0.38% and by ethanol solvent was 0.08%. Antimicrobial activity of Sonnerati caseolaris fruits ethyl acetate extract obtained significant was from P0.05 of iEscherechia.coli and iCandida albicans but not significant of iStaphylococcus aureus . The Sonneratia caseolaris extracted by ethanol 70% solvents was highly promising among iEscherichia coli , iStaphylococcus aureus and iCandida albicans with level of significance was from P 0.05. The study suggests iSonneratia caseolaris fruits as a potential source of bioactive compounds with stable antioxidative and antimicrobial properties and can be used as natural antimicrobial/antioxidative agents in clinical, pharmaceutical and food processing industries.
