Abstract: The GC-MS technique was applied to analyze the volatile oil extracted by steam distillation from Cymbopogon citrates(DC.) Stapf that came from five different regions, and the chemical components of the volatile oil in different samples were compared. The results showed that in all five samples tested, the content of volatile oil in leaves was the highest, followed by the whole plant and then the stem. The types and contents of volatile components in C. citrates from different regions were different. The volatile oils in the whole plant from Hunan, Guangdong, Zhejiang, Hainan and Fujian were identified as 36, 30, 37, 22, 33 species components, respectively, and the volatile oils in the leaves were identified as 25, 24, 32, 27, 39 species components, respectively. The main constituents were identified as E-citral, Z-citral, β-myrcene and geraniol, etc. The volatile oil and whole plant has the highest amount of citral (about 70%-85%), with E-citral of 40.86%-51.15% and Z-citral of 31.01%-36.46%. The contents of β-myrcene and geraniol were 1.94%-15.43% and 1.61%-4.89%, respectively. The components of volatile oil in whole plant and leaves were mainly oxygenated monoterpenes (81.91%-93.04%) and with the characteristics of localization.
