## Abstract
Efforts to purify patchouli alcohol from patchouli oil (Pogostemon cablin Benth.) have been carried out. The patchouli oil was obtained from Bone-Bone village, Baraka sub-district, Enrekang Regency, South Sulawesi, Indonesia. The purification was conducted using vacuum fractionation distillation method with a pressure of 96 kPa. Identification of fractions was carried out by the GCMS method. By this method, four fractions and one raffinate were obtained, namely fraction I (141-142°C), fraction II (145-148°C), fraction III (149-150°C), fraction IV (151-152°C), and raffinate. Patchouli alcohol content in each fraction was 9.76%, 10.86%, 45.37% and 70.34%; while in raffinate was 0%. Based on these results, this method is superior to previous methods, and the fraction IV is suitable to be used as a precursor in derivatization of patchouli alcohol.
