Objective: To analyze constituents in the volatile oils extracted from stems and leaves

root tubers and its processed products of Curcuma kwangsiensis. Method: Volatile oils of C. kwangsiensis were extracted through steam distillation

and the constituents were separated and identified by using GC-MS. Result: Thirty-seven chemical components were determined in volatile oil from stems and leaves of curcumae kwangsiensis

22 chemical components were determined in volatile oil from root tubers of C.kwangsiensis and 32 chemical components were determined in volatile oil from its processed products. Conclusion: Chemical components in volatile oils were different in three samples.
