摘　　要：目的分析葱白的低极性挥发性组分。方法采用超临界二氧化碳（CO2）萃取法从葱白中提取挥发油；再用硅胶柱层析法，以石油醚（30～60℃）为流动相，按极性由小到大得到组分A和组分B；最后用气相色谱-质谱联用技术对两个组分进行成分分析，并用归一化法确定各化学成分的相对百分含量。结果组分A和组分B共分离、鉴定出16种化合物，主要含二萜类、脂肪酸类、黄酮类、烷烃类和含硫类化合物。结论了解葱白超临界萃取挥发性组分中低极性组分的化学成分，为中药制剂搏心通的开发奠定基础。Objective To analyze the chemical components of essential oil from Congbai. Methods The volatile oil was extracted with supercritical carbon dioxide, the components in which and contents were determined by GC-MS and normalization method. Results 16 components from Congbai by SFE were separated and identified. The main compounds of volatile oil were diterpenoids, fatty acids, alkanes, organosulfur compounds. Conclusion We have investigated the low polarity gradients from the volatile part of Congbai, the way of which benefits for further studying of Congbai .
