| Summary: | The aim of this study to compare percent chemical composition of essential oil contained in Pogostemon cablin using different methods. Essential oil of Pogostemon cablin, cultivated in Biotechnology, Malacca, was obtained by hydrodistillation, solvent extraction and soxhlet extraction methods. The oils were analysed by capillary gas chromatography using flame ionization and mass spectrometric detections. The compounds were identified according to their retention indices and mass spectra (EI, 70 eV). This experiment showed the best method to extract the essential oil from Pogostemon cablin is hydrodistillation.Two major compounds were identified from the extraction of Pogostemon cablin. The first major components of Pogestemon cablin is patchoulli oil followed by azulene. The results found that extraction of essential oil was highest by hydrodistillation where patchoulli oil (44.70%) followed by azulene (9.58% and 9.68%). Meanwhile soxhlet extraction method gave the lowest composition of essential oil where only (26.66%) patchoulli oil obtained followed by azulene (5.73% and 6.11%) |
