Essential oils are volatile aromatic compounds that are found in herbal plants. Extraction method of plant essential oils can extraction yield, percentage and type of chemical compounds extant in the change. In this research, essential oil product from Trachyspermum ammi (T. ammi) seeds was extracted using subcritical water and further analyzed by GC and GC-MS for determination of chemical compositions. The effect of various parameters on SWE such as temperature, water flow rate and mean particle size were investigated using Taguchi experimental design method. The optimum conditions were obtained from S/N ratio analysis, respectively, at temperature of 175 °C, flow rate 2 mL/min and mean particle size 0.25 mm.
