THE STUDY ON THE EXTRACTION OF PLECTRANTHUS AMBOINICUS (LOUR.) SPRENG ESSENTIAL OIL BY THE STEAM DISTILLATION

Abstract

The objectives of this research were to test chemical composition and some anti- microorganism activities of Plectranthus amboinicus (Lour.) Spreng essential oil, in Cu Chi district, Ho Chi Minh City. In this study, the volatile oil was obtained by the steam distillation. The chemical composition of volatile oil was characterized by GC–MS. While the anti-microorganism was tested by Minimum Inhibitory Concentration method (MIC). It shows that, the main chemical compounds of Plectranthus amboinicus (Lour.) Spreng essential oil are Carvacrol (63,29%), Caryophyllene (12,39%). That essential oil is good anti-microorganism agent.
Keywords: essential oil, plectranthus amboinicus (Lour.) Spreng, distillation, GC-MS.
