This study aims to isolate the secondary metabolite compounds contained in the ethyl acetate extract in bark of L.coromandelica. Isolation was carried out through several stages, ranging from maceration, fractionation, purity testing, and identification. The isolates obtained was white crystals in the form of needles with a melting point 133-134°C, with Lieberman-Buchard reagents gave positive results. The IR spectrum absorption area showed the existence of several functional groups at wavelength namely 3446.79 cm −1 (O-H), 2935.66 cm −1 (C-H); 2866.22 cm −1 (C-H), 1463.97 cm −1 (-C-H2), 1377.17 cm −1 (-C-H3), 1643.35 cm −1 (C=C), 1047.35 cm −1 (C-O). Based on the reagent test and IR spectrum data, the crystals obtained are a group of steroid compounds.
