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%)。The volatile components of the seed of micro-extraction and GC-MS in hyphenation, and their comphor tree were separated and identified by solid phase 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. 890%）, limonene （12.68%）, a-pinene （4. 42%）, camphene （2. 69%）, aromadendrene （2.34%）, o-eymene （2.26%）, β-pinene （2. 12%）.
