Analysis of the essential oil from Brassica rapa L.root by GC-MS
Objective To analyze the chemical constituents of the essential oil from Brassica rapa L.. Methods The essential oil of Brassica rapa L. was extracted by steam distillation. The chemical components of the essential oil were analyzed by GC-MS and the relative content of volatile oil was determined by peak area normalization method.Results 38 peaks were separated totally ,35 components were identified, and which accounted for 96.55% of the total content of the volatile oil.
