Abstract: Tbe yields of the essential oil were acquired with 0.8% and 2.6% respectively by steamdistillating of the roots of Kaempferia galanga L. collected at Yunnan and Guangdong. The essential oils were analysed by combination of chromatography, deri-vative preparation and GC/MS/DS. As a result, 31 constituents were identified as the following: α-thujene α-pinene, camphene, benzaldehyde, sabinene, β- pinene, α-phellandrene, Δ3-carene, p-cymene, limonene, 1, 8-cineole, β-phe- llandrene, p-methoxy-styrene, borneol, terpin- 4 -ol, α-terpineol, eucarvone, anisaldehyde, bornyl acetate, thymol, α-terpinyl acetata, cis-ethyl-cinnamate, β-elemene, δ-selinene, trans-etbyl-cinnamate, pentadecane, γ-cadinene, hexa- decane, cis-p-methoxy-ethyl-cinnamat heptadecane, trans-p-methoxy-ethyl-cinnamate.
