The chemical composition and aroma profile of seven Rosa damascena Mill. essential oil samples from Saudi Arabia (Al‐Shafa, Al‐Hada and Al‐Taif area) were studied in details by means of gas chromatography‐mass spectrometry (GC/MS) and gas chromatography with flame ionization detection (GC‐FID). As a result, more than 120 compounds, containing C3‐C27 carbon atoms, mainly mono‐ and sesquiterpenoids, were identified by GC/MS. Fifty‐two components with concentration >0.01%, which represents 97.5%‐99.5% of the total detected compounds, were quantified by means of GC‐FID. The main compounds of essential oil samples from Saudi Arabia are as follows: citronellol (19.64%‐28.13%), geraniol (18.29%‐27.23%), nerol (7.02%‐14.27%), linalool (2.93%‐7.55%), β‐phenylethyl alcohol (1.77%‐3.87%) and n‐paraffins (13.53%‐30.85%). An olfactory evaluation of the samples was performed, as well. A sample of Bulgarian Rosa damascena Mill. distilled rose oil was analysed in addition, and its chemical profile and olfactive characteristics were compared to these of the oils from Saudi Arabia. The results for the chemical composition of the rose oil samples allowed revealing the similarity between the samples by using cluster analysis. The Saudi Arabia rose oils, despite do not fully comply with the ISO 9842:2003 standard for rose oil, reveal a high olfactive potential.

沙特阿拉伯和保加利亚玫瑰油化学特性的比较研究:技术和地理起源的影响

七个Rosa damascena Mill的化学成分和香气特征。通过气相色谱-质谱(GC / MS)和带火焰离子化检测的气相色谱(GC-FID)对沙特阿拉伯(Al-Shafa,Al-Hada和Al-Taif地区)的精油样品进行了详细研究。结果,包含C 3 -C 27的120多种化合物通过GC / MS鉴定了碳原子,主要是单萜和倍半萜。通过GC-FID定量分析了52种浓度> 0.01%的成分,占检测到的化合物总数的97.5%-99.5%。来自沙特阿拉伯的精油样品的主要化合物如下:香茅酚(19.64%‐28.13%),香叶醇(18.29%‐27.23%),神经醇(7.02%‐14.27%),芳樟醇(2.93%‐7.55%), β-苯乙醇(1.77%-3.87%)和正链烷烃(13.53%-30.85%)。还对样品进行嗅觉评价。保加利亚罗莎(Rosa damascena)的样本磨。此外,还分析了蒸馏玫瑰油,并将其化学特性和嗅觉特性与沙特阿拉伯的这些油进行了比较。通过使用聚类分析,玫瑰油样品化学成分的结果可以揭示样品之间的相似性。尽管不完全符合ISO 9842:2003玫瑰油标准,但沙特阿拉伯玫瑰油仍具有很高的嗅觉潜力。
