ß-sitosterol is an essential bioactive phytosterol naturally present in plant cell membranes. It has a coincident structure with animal cholesterol . This investigation reported isolation, structure analysis, and an antimicrobial assay of ß-sitosterol from the root bark of Bakau Minyak (Rhizophoraapiculata) from Lampung coastal . The isolation of ß-sitosterol was carried out through maceration using methanol, separation by vacuum liquid chromatography (VLC), and purification by column chromatography (CC) using ethyl acetate/n- hexane (2: 8) as eluent. The structure of ß-sitosterol was determined using spectroscopic analysis (UV-Vis, FT-IR,13C-NMR, 1H-NMR, DEPT,and GC-MS). The pure ß-sitosterol has 107.4 mg of white needle crystalline compound, the compound melting point about 140.7 - 141.2°C, the molecular mass confirmed by m/z 414, and UV absorption detected at λ 203.9 nm. The ß-sitosterol antimicrobial bioactivity assay has shown potential activity to be developed as a lead compound against E. colli.
