The aims of this study were to obtain phytochemical content and to examine antibacterial activity potency of methanol extract of Rhyzophora mucronata. The phytochemical screening was assayed by qualitative analysis and the antibacterial assay determined by disk diffusion method. The results of phytochemical analysis showed that all methanol extract of root, bark, leaf, fruit and flower of R. mucronata contained alkaloid, tannin, and flavonoid, in addition fruit contained steroid., respectively. The antibacterial activity in gram positive bacteria (Staphylococcus aureus) and gram negative bacteria (Escherichia coli) was showed by almost all extracts of root, bark, wood, flower and leaf of R. mucronata.
