Analysis of the Essential Oil of Indonesian Patchouli (Pogostemon cablin Benth.) Using GC/MS (EI/CI)

Journal of Essential Oil Research: JEOR, Jan/Feb 2004 by Bure, Corinne M, Sellier, Nicole M

Results and Discussion

The constituents of patchouli oil are listed in Table I according to their elution order on the CP-Sil-5-CB-MS column. The chromatogram of the oil indicated 41 peaks of which 28 were identified. The nature and the chemical functions of the 13 non-identified compounds were determined by the use of deuterated ammonia (23) ND^sub 3^ as a reagent gas in positive ion chemical ionization. Among these ones, we found seven sesquiterpene hydrocarbons (2.0%) and six sesquiterpene alcohols (3.0%).
