Ujung atap (Baeckea frutescens L) from Myrtaceae family is a woody shrub which leaves resemble a large evergreen tree found from Nanjung River Village, Ketapang Regency, West Kalimantan.  The purpose of this study is to isolate and characterize essential oils of ujung atap. Insulation is used by the distillation method. The result showed rendement of ujung atap the essential oils are 0,91% (4 hours), 0,97% (6 hours) dan 1,12% (7 hours). Essential oils are tested physicochemistry properties and components of chemistry compound analyzed with GC-MS. The result showed density is 0,878 (room temperature), refractive index is 1,474 (28oC), optical rotation is +2,24(20oC), solubility in alcohol is 1:8 mL, acid number 1,253, dan ester number 3,829. The result of GC-MS showed 21 compound, with the main compound monoterpenes are α-pinene, β-pinene and 1,8 cineol.
