Abstract：Objective To optimize the extraction technology and analyze the chemical composition of Maca volatile oil. Methods The yields of Maca volatile oil were investigated to compare different extraction technologies, including steam distillation (water), steam distillation ( salt water) , ultrasonic extraction method of petroleum ether and petroleum? ether soak extraction method. GC-MS was used to analyze the chemical composition of the volatile oil. Results Among the 4 methods, the steam distillation ( salt water) showed highest yield of Maca volatile oil. 78 chromatographic peaks were detected in the volatile oil sample by GC-MS and 26 chemi-cal compositions were identified, most of which were unsaturated components. Conclusion Steam distillation ( salt water) is an opti-mized method of extracting Maca volatile oil. phenylacetonitrile and benzyl isothiocyanate are main constituents of Maca volatilel oil ac-cording the GC-MS results.
