[Objective] To investigate effects of different elevations on ginseng volatile oil contents and their variation law.[Methods] The volatile oil of ginseng was extracted by steam distillation method,and the volume fractions of volatile oil components were calculated by area normalization method.The separated components were identified and determined by GC-MS.[Results] The content and composition of volatile oil in 4-year old RADIX ET RHIZOMA GINSENG at different elevations regions were quite different.[Conclusion]Elevation has a certain impact on the components and relative contents of ginseng volatile oil,and ginseng volatile oil content increases with the rise of elevation.
