山腊梅中挥发油成分分析

Analysis of Volatile Components in Essential Oil of Chimonanthus nitens by Capillary Gas Chromatography-Mass Spectrometry

采用挥发油萃取器蒸馏法提取山腊梅(Chimonanthus nitens)叶的挥发油性成分,经毛细管气相色谱-质谱联用仪(GC-MS)分析,鉴定了其中的72个挥发性化合物。其挥发性组分主要是烯烃类、醇类物质,其相对含量分别是42.43%和39.60%。该法获得的相对含量最高的是脱氢香橙烯(7.97%),其次是(-)-匙叶桉油烯醇(7.25%),α-杜松醇(7.08%),(+)-匙叶桉油烯醇(6.19%),其它含量较高的成分依次是:△-杜松烯(4.80%),E-环氧金合欢烯(4.36%),石竹烯(4.06%),杉木醇(3.75%),十六烷酸(3.66%),(-)-氧化石竹烯(3.37%)。

The essential oil of Chimonanthus nitens was extracted by the volatile oil extractor, and analyzed by capillary gas chromatograph - mass spectrometry. Seventy two volatile components were identified and their relative contents were determined. It was found that the main volatile components were of alkenes（42.43% ） and alcohols（39.60% ）, in which the predominant compounds were dehydroaromadendrene （ 7.97% ）, （ - ） -Spathulenol （ 7. 25% ）, alpha-Cadinol （ 7.08% ）, （ ＋ ） -Spathulenol （6. 19% ）, delta-Cadinene（4. 80% ）, E-Farnesene Muurolol （3.75%）, n-Hexadeeanoic acid （3.66%） epoxide （4.36%）, Caryophyllene （4. 06% ）, Tau , and （ - ）-Caryophyllene oxide（3.37% ）.
