    Abstract:
    OBJECTIVE: To analyze the essential oil from the rhizome of Curcuma aromatica of different growth periods, and to provide the scientific reference for reasonable cultivation and quality control of this plant. METHODS: The essential oil was extracted by hydrodistillation and analyzed with GC-MS. The relative contents were determined with area normalization method. RESULTS: The main volatile constituents in the rhizome of Curcuma aromatica were basically the same. Among these volatile constituents, curdione was the major. The relative content of curdione was 16.35% in the rhizome of wild plant in Hengxian county, and 15.81% in the rhizome of one-year-old plant in Mingyang farm, Nanning city. The relative content of eucalyptol in the 2-year-old cultivated rhizome in Hengxian county was 15.40%, and 14.59% in the rhizome of wild plant in Hengxian county. beta-Elemene, beta-caryophyllene,eugenol and germacrone were also the main constituents in the rhizome essential oil. CONCLUSION: Volatile constituents in the rhizome of Curcuma aromatica are similar to each other,but the relative content of each component is different. This result can provide the scientific foundation for the cultivation of Curcuma aromatica.
