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 Poncirus canadensis in different seasons. Methods: Volatile oil of Paphia bracteatum was extracted by steam distillation. The chemical constituents were identified by gas chromatography - mass spectrometry. The content of each component was determined by area normalization. Results: Fifty-one and thirty-two components were identified from the volatile oil of Ponchus chinensis in the spring and autumn, accounting for 80.66% and 90.85% of the total volatile oil, respectively. Conclusion: The volatile oil of Ponchosia is mainly terpenoids in spring and autumn, the chemical composition of more than 2.00% is the same.
