| Abstract: | The essential oil of Pogostemon cablin from Suixi county,Zhanjiang City,Guangdong Province was extracted by steam distillation and analyzed by gas chromatography-mass spectrometry(GC-MS).Meanwhile,the temperature-programmedretention index (PTRI) was employed to improve the accuracy of qualitative analysis.The relative concentration of each component was determined by peak area normalization.A total of 90 compounds were isolated,of which 50 compounds were chemically identified and accounted for 72.53% of the total peak area.The major components identified were Patchouli alcohol(24.88%),.delta.-Guaiene(16.05%),.alpha.-Patchoulene(7.61%),.alpha.-Guaiene(7.36%),Caryophyllene(3.63%),.beta.-Patchoulene(3.38%),.beta.-Elemene(1.5%) and Isocaryophillene(1.0%). |
