目的 :分析明党参加工炮制前后的顶空气体成分 ,探讨其是否与明党参的致敏性有关。方法 :采用毛细管气相色谱 质谱 计算机联用方法分析明党参炮制前、炮制过程中、炮制后顶空气体成分。结果 :初步鉴定出 2 4个化合物。炮制前的主要成分是 :8 羟基 对伞花烃 (7.72 % )、4 甲基 2 ,6 二叔丁基苯酚 (7.48% )、1,2 二苯乙烯 (8.12 % )。炮制过程中的主要成分是 :联苯 (13.44 % )、十五烷 (9.6 4% )、β 乙基萘 (8.37% )。炮制后的主要成分是 :β 蒎烯 (5 2 .17% )、α 蒎烯(2 2 .0 9% )、柠檬烯 (13.0 4% )、α 异松油烯 (8.6 9% )。结论 :三者顶空气体成分的化学组成呈明显差异。
Objectives: To analyze the composition of the headspace gas before and after the Party’s participation in the artillery processing, and to explore whether it is related to the allergenicity of the radix pilosula. Methods :Analysis of the components of the top air body before, during and after processing of Radix Codonopsis by computerized method with capillary gas chromatograph and mass spectrometry. Results: Twenty-four compounds were initially identified. The main components before processing were: 8 hydroxy paraffin (7.72%), 4 methyl 2, 6 di-tert-butylphenol (7.48%), and 1,2-stilbene (8.12%). The main components in the processing are: biphenyl (13.44 %), pentadecane (9.64%), and beta ethyl naphthalene (8.37%). The main components after processing were: β-terpene (52.17%), α-limonene (20.29%), limonene (13.04%), and α-terpinene (8.69%). Conclusion : The chemical composition of the three components of the top air body is significantly different.
