摘要
采用固相微萃取-气相色谱质谱法分离和鉴定千里光挥发油成分,用归一化法测定其相对含量。共分离出93个组分,鉴定出71种化学物,其含量占总挥发油组分峰面积的96.39%。主要挥发成分及其含量为十四烯(11.55%)、4乙烯基苯酚(10.99%)、δ-榄香烯(10.25%)、4-乙烯基-2甲氧基-苯酚(9.75%)、莰烯(8.7%)、(E,E)-α-金合欢烯(7.1%)和三环烯(4.6%)等。
Components of volatile oil in Senecio scandens Buch.-Ham. were separated and identified by solid phase micro-extraction （SPME） and GC-MS in hyphenation, and their relative contents （in %） were found by the method of normalization. Totally 93 compounds were separated, among which 71 compounds were identified and determined, amounting to 96.39% of the total peak areas of the components of the volatile oil. The main compounds found with their relative contents were as follows.- tetradecene （11. 55%）, 4-vinylphenol （10. 99%）, 8-elemene （10. 25%）, 4-vinyb2-methoxyphenol （9. 75%）, camphene （8. 7%）, （E, E）-a-farnesene （7. 1%） and tricyclene （4.6%）.
