摘要:

以贵州黔南平塘县、陕西三原县两个地区种植的大马士革玫瑰花为材料,建立玫瑰花精油提取分离以及主要挥发性成分的鉴定方法,通过改进分析方法,比较不同地区种植的大马士革玫瑰花精油的主要香气成分。利用水蒸气蒸馏法提取玫瑰花精油,应用气相色谱-质谱联用(GC-MS)法对提取的玫瑰花精油成分进行定性分离鉴定。共鉴定28种主要化合物,与国际标准中玫瑰精油的组成成分及相对含量范围基本一致。所测的几种化学成分精密度、重复性和稳定性良好;加标回收率为97.1%~99.4%,RSD为0.80%~1.50%。不同产地的大马士革玫瑰花精油的主要成分和相对含量有一定差异,各具特色。本实验建立的分析方法稳定,适合玫瑰花精油的成分分析。

Abstract: To establish a method for extracting and separating rose essential oil and the separation and identification of main volatile components from damascus Rose a planted in Pingtang County of Guizhou Province and Sanyuan County of Shaanxi Province, the analytical methods were improved to compare the main aroma components of damascus Rose essential oil grown in different regions by improving the analytical methods. Rose essential oil was extracted by steam distillation, and the extracted rose essential oil components were qualitatively separated and identified by gas chromatography-mass spectrometry (GC-MS). A total of 28 major compounds were identified, which are basically consistent with the composition and relative content of rose essential oils in international standards. The precision, repeatability and stability of several chemical components tested were great; the recoveries were 97.1%-99.4%, and the RSD was 0.80%-1.50%. The main components and relative contents of damascus Rose essential oils from different regions have different characteristics and different characteristics. The analytical method established in this experiment is stable and suitable for the composition analysis of rose essential oil.
