摘　　要：目的:研究不同季节一年蓬花挥发油的化学成分。方法:采用水蒸气蒸馏法提取一年蓬花的挥发油,用气相色谱-质谱联用仪对其化学成分进行鉴定,采用面积归一法测定了各组分的含量。结果:从春季和秋季一年蓬花挥发油中分别鉴定出51,32个组分,分别占其挥发油总量的80.66%,90.85%。结论:春季和秋季一年蓬花挥发油以萜类化合物为主,高于2.00%的化学成分相同。Objective： To study the chemical constituents of volatile oil from different season flowers of Erigeron annus. Method： The volatile oil was extracted by steam distillation and analyzed by GC-MS. The relative content of each component was determined by area normalization. Result： Fifty-one and thirty-two compounds were identified from the spring and autumn flowers of E. annus, representing 80.66% and 90.85% of the total content, respectively. Conclusion： Terpenes are found to be the dominant components and the chemical constituents over 2.00% are the same in the volatile oil from different season flowers of E. annus.
