Triterpenoid isolation from n-hexane extract of kayu ara leaves ( Ficus aurata (Miq.) Miq) has been performed. The Isolation has been done by column chromatography method using silica gel as a stationary phase and n-hexane and ethyl acetate as mobile phase with isocratic method and it is continued by trituration method. Isolated compound has white amorphous shape, decomposed at 86-87oC and gives single spot with reddish brown violet in LB reagent and in H 2 SO 4 reagent on TLC test. UV spectra indicate the presence of double bonds in the isolated compound at 204 nm λmax and IR spectra showed -OH functional group at 3290 cm -1 , -CH stretching at 2912,90 cm -1 , C=C at 1676 cm -1 , C-O stretching at 1054,93 cm -1 , and at 1374 cm -1 is spectra of geminal dimethyl compound that are characteristic of triterpenoids which supports ultraviolet spectroscopic data. Antibacterial activity test showed that isolated compound is active in inhibiting the growth of gram-positive bacteria Staphyloccocus aureus and gram-negative bacteria Escherichia coli .
