福建产大马士革玫瑰精油成分GC-MS分析

    Component Analysis of the Essential Oil of Rosa damascena from Fujian by GC-MS

    • 摘要: 研究福建产大马士革玫瑰精油中的挥发性成分,为其香气品质评价和开发利用提供科学依据。采用顶空固相微萃取和气相质谱联用技术(HS-SPME/GC-MS)测定水蒸气蒸馏提取的福建产大马士革玫瑰精油中的挥发性成分。结果表明:从大马士革玫瑰精油中共分离鉴定出154种挥发性成分,相对总含量为97.68%,主要含醇类、酯类、醛类、酮类、酸类、萜烯类、烷烃类、芳香族类等成分,其中以萜烯类成分的数量最多,达61种,相对含量达48.14%。大马士革玫瑰精油中相对含量较高的挥发性成分有(R)-(+)-β-香茅醇、蒎烯、β-石竹烯、α-愈创木烯、α-石竹烯、牻牛儿酸甲酯,相对含量分别为20.18%、7.11%、6.24%、5.38%、4.37%、4.20%。萜烯类、醇类、酯类是构成大马士革玫瑰精油香气的主要物质基础,赋予了大马士革玫瑰精油花香、果香、草香等多种香味,香味层次丰富。

       

      Abstract: The volatile components in the essential oil of Rosa damascena from Fujian Province were studied to provide scientific basis for the quality evaluation and development and utilization of aroma. The volatile components in the essential oil of Rosa damascena produced in Fujian Province extracted by steam distillation were determined by using the headspace solid-phase microextraction and gas chromatography-mass spectrometry technology (HS-SPME/GC-MS). The results showed that a total of 154 volatile components were isolated and identified from the essential oil of Rosa damascena, with the relative total content of 97.68%, mainly containing alcohols, esters, aldehydes, ketones, acids, terpenes, alkanes and aromatic compounds. Among them, the number of terpenes was the largest, reaching 61 species, and the relative content was up to 48.14%. The volatile components in the essential oil of Rosa damascena with higher relative content were (R)-(+)-β-citronellol, pinene, β-caryophyllene, α-guaiene, α-caryophyllene, geranic acid methyl, and their relative contents were 20.18%, 7.11%, 6.24%, 5.38%, 4.37% and 4.20%, respectively. Terpenes, alcohols and esters were the main material basis of the aroma of essential oil from Rosa damascena, which endowed the essential oil of Rosa damascena with floral, fruity and grassy fragrance with rich fragrance levels.
