摘要
采用气质联用法(GC-MS)对不同产地(山东、云南、安徽、江苏、新疆)的姜油中的挥发性成分进行分析和比较。采用双柱(DB-1柱和HP-INNOWAX柱)保留指数(RI)辅助定性,气相色谱(GC)面积归一法定量。研究过程中,成功分离分析出醇类、酮类、烯烃类、酯类、醛类、杂环类、芳香类化合物等共计64种成分,其组成成分平均含量最高为姜烯(29.7%),其它依次为β-倍半水芹烯(12.28%)、α-姜黄烯(9.7%)、β-水芹烯+1,8-桉叶素+苧烯(7.5%)、γ-杜松烯+α-金合欢烯(7.0%)、β-红没药烯(6.9%)和莰烯(5.7%)等。对比结果表明,不同产地的姜油含有几乎相同的化学成分,但含量存在差异。
This paper reports analysis and comparison of volatile components of oil of ginger （Zingiberofficinale Roscoe） produced from different areas in China （Shandong, Yunnan, Anhui, Jiangsu and Xinjiang） by Gas Chromatography-Mass Spectrometry （GC-MS）. The qualitative analysis was supported by retention index （RI） on two columns （DB-1 column and HP-INNOWAX column）. The quantification of components was based on peak area in GC. In the study, totally 64 volatile components were successfully separated and identified, including alcohols, ketones, olefins, esters, aldehydes and heterocyclic components. It was found that Zingiberene was the highest level volatile component （29.68%）, followed by β-sesquiphellandrene （12.3%）, α-curcumene （9. 7%）, β-phellandrene ＋ 1,8-eineole ＋ limonene （7. 5%）, β-bisabolene （6. 9%）, and camphene （5.7%）. The results show that ginger oil produced at different areas contain almost same components but in different quantities.
