目的分析新疆芜菁根挥发油的化学成分。方法采用水蒸气蒸馏法提取芜菁根中的挥发油,以气相色谱质谱联用技术对其化学成分进行分析,用峰面积归一化法得到各组分的相对含量。结果从芜菁根挥发油中共分离出38个峰,鉴定出了35个成分,占挥发油总含量的96.55%。结论芜菁挥发油主要成分为异硫氰酸酯、腈类、少量醛和萜类化合物。 Objective To analyze the chemical constituents of the essential oil of Xinjiang turnip root. Methods Volatile oil from root of turnip was extracted by steam distillation. The chemical constituents were analyzed by gas chromatography-mass spectrometry. The relative contents of each component were obtained by normalizing peak area. Results A total of 38 peaks were isolated from the volatile oil of turnip root. 35 components were identified, accounting for 96.55% of the total volatile oil content. Conclusion The main constituents of turnip volatile oil is isothiocyanate, nitriles, a small amount of aldehydes and terpenoids.
