摘要
以湛江市遂溪县产藿香为研究对象,采用水蒸气蒸馏法提取藿香的挥发油成分,利用气相色谱—质谱联用技术结合程序升温保留指数进行定性分析,采用峰面积归一法进行定量分析.共分离出90种化学成分,鉴定了50种化合物,占挥发油总量的72.53%,主要成分有广霍香醇(24.88%)、δ-愈创木烯(16.05%)、α-广藿香烯(7.61%)、α-愈创木烯(7.36%)、丁香烯(3.63%)、β-广藿香烯(3.38%)、β-榄香烯(1.5%)和γ-丁香烯(1.0%).
The essential oil of Pogostemon cablin from Suixi county, Zhanjiang City, Guang- dong Province was extracted by steam distillation and analyzed by gas chromatography- mass spectrometry （GC-MS）. Meanwhile, the temperature-programmedretention index （PTRI） was employed to improve the accuracy of qualitative analysis.The relative concen- tration of each component was determined by peak area normalization. A total of 90 com- pounds were isolated, of which 50 compounds were chemically identified and accounted for 72.53% of the total peak area. The major components identified were Patchouli alcohol （24.88%） ,. delta.-Guaiene （ 16.05% ） ,. alpha.-Patchoulene （7.61%） , alpha.-Guaiene （ 7.36% ）, Caryophyllene （ 3.63% ） ,. beta.-Patchoulene （ 3.38% ） ,. beta.-Elemene （ 1.5% ） and Isocarvophillene （ 1.0% ）.
