The physical characteristic test of patchouli oil has been done, including the density relative, optical rotation, refractive index and solubility in alcohol. Based on the experiment, physical characteristic has fulfilled standard. The chemical compounds of sample was being analized by gas chromatography method. The major component of patchouli oil is patchouli alcohol with 31.09 % of level. Sample contains Fe contaminant of 24,25 ppm. To decrease Fe content, extraction with 2 % (w/w) citric acid as chelating agent with reaction 60 minutes. This extraction process could decrease Fe content become 3.20 ppm.
Key words: Patchouli oil, chelating agent, citric acid, Fe content.
