不同岩蔷薇浸膏挥发性致香成分的SED-GC-MS分析研究

Analysis. ＆ Research of Volatile Aromatic Substances in Different Labdanum Concert with SED-GC-MS Method

采用同时蒸馏-萃取装置分别提取国产及进口岩蔷薇浸膏中挥发性物质，将其进行GC-MS分析。结果显示：国产岩蔷薇浸膏中挥发油含量为10．52％，进口岩蔷薇浸膏中挥发油含量为21．80％。分别从国产及进口岩蔷薇浸膏中鉴定了48种和38种挥发性成分。对比进行感官评价表明：国产岩蔷薇浸膏香气特征明显，具有典型的龙涎香-琥珀膏香香气，但余味欠干净需控制用量谨慎使用。进口岩蔷薇浸膏似经过人工复配，特征明显，与烟草的配伍性表现良好。

Use simultaneous distillstion and extraction facility to extract volatiles respectively fromlocal and imported labdanum concrete and then conduct GC-MS analysis of them. The results showed that content of volatile otis in local labdanum concrete took 10.52% proportion whereas those in the imported one took 21.80% .Meanwhile,there were 48 and 38 volatile substances identified in local labdanum and imported one respectively. Sensory evaluation of the two differently-originated materials demonstrated that local lalxlanum had distinct characteristic aroma of typical ambergris and amber, however its after taste was not dean enough so that dosage shall be controlled carefully when applied. Imported labdanum concrete seemed to have been synthesized,it also has distinct characteristics and it could match with tobacco flavor in harmony.
