固相微萃取-气相色谱-质谱法分析香樟籽挥发性成分

GC-MS Determination of Volatile Components of the Seeds of Camphor Tree with Solid Phase Micro-extraction

摘要: 采用固相微萃取-气相色谱-质谱法分离和鉴定香樟籽的挥发性成分,用归一化法测定其相对含量。共分离出76种组分,鉴定出47种化合物,其含量占总挥发性成分的97.4%。主要挥发成分为樟脑(57.89%)、柠檬烯(12.68%)、α-蒎烯(4.42%)、莰烯(2.69%)、香橙烯(2.34%)、伞花烃(2.26%)及β-蒎烯(2.12%)。

Abstract: The volatile components of the seed of comphor tree were separated and identified by solid phase micro-extraction and GC-MS in hyphenation, and their relative contents (in %) were found by the method of normalization. Totally 76 compounds were separated among which 47 compounds were identified and determined, amounting to 97.4% of the total peak areas of the volatile components. The main compounds found were as follows (relative %): camphor (57.89%), limonene (12.68%), α-pinene (4.42%), camphene (2.69%), aromadendrene (2.34%), o-cymene (2.26%), β-pinene (2.12%).
