摘　　要：目的分析研究白英挥发油的主要化学成分。方法采用水蒸气蒸馏法从白英中提取挥发油。用气相色谱-质谱联用法对其化学成分进行鉴定,用归一化法计算各组分的相对百分含量。结果分离得到154个化学组分峰,并确定出其中47个化学成分,占挥发油总量的83.23%。结论主要成分为棕榈酸和亚油酸。Objective To analyze chemical constituents of the volatile oil from Solynum larytum Thunb. Methods The volatile oil was extracted from Solynum larytum Thunb. by steam distillation. The components of the volatile oil were separated and identified by GC-MS. The relative content of each component was determined by area normalization. Results One hundred and fifty - four kinds of components were separated. Among them, forty-seven components were identified, accounting about 83.23% of the total volatile oil. Conclusion Hexadecanoic acid and linoleic acid are the most abundant components with the concentration of 42.79% and 19.97% respectively.
