This study was conducted to investigate the pyrolysis products of patchouli oil by Curie-Point pyrolysis. The pyrolysis of patchouli oil was performed at the temperature of 16$0^{circ}C$, 42$0^{circ}C$, $650^{circ}C$, 76$0^{circ}C$, and 92$0^{circ}C$ by Curie-Point Pyrolyzer. The pyrolysis products were analyzed by gas chromatography(GC) and mass selective detector(MSD). Total 21 components were identified in the pyrolyzates of patchouli oil. The temperature for maximum formation of most of these compounds was in the range of 76$0^{circ}C$~92$0^{circ}C$. The major components were $eta$-patchoulene, $alpha$-guaiene, $eta$-caryophyllene, $alpha$-patchoulene, seychellene, $delta$-guaiene, and patchouli alcohol. The numbers of the pyrolyzed products of patchouli oil were increased by increasing temperature, however, the yields of major components such as patchoulene, guaiene, seychellene and patchouli alcohol decreased as the temperature of pyrolysis was raised to 92$0^{circ}C$, the highest temperature in this experiment. The optimum temperature for formation of the pyrolysis products such as styrene, indane and naphthalene was at 92$0^{circ}C$.
