Abstract

ABSTRACT This study illustrates the importance of multivariate analysis in profiling the levels of 104 volatiles across 14 modern rose cultivars obtained using headspace gas chromatography–mass spectrometry analysis. Despite differences in the abundance of volatiles, the cultivars ‘Lady Emma Hamilton’, ‘Golden Celebration’ and ‘The Poet’s Wife’ share similar profiles of volatile organic compounds (VOCs) and the absence of phenethyl alcohol, which is usually associated with a characteristic ‘rose’ fragrance. R. ‘Hansa’ is the cultivar with the greatest abundance of volatiles, with high levels of acyclic monoterpenes and aromatic compounds. No monoterpenes were detected from the climbing rose R. ‘August Gervais’. The study revealed that highly fragrant cultivars tend to produce VOCs in higher intensity and greater diversity. These findings also demonstrate the potential of using headspace analysis to compare the natural aromas of rose cultivars, which provides information to inspire innovation in the perfumery and food industries. Abbreviations AMT, acyclic monoterpenes; ARM, aromatic compounds; CMT, cyclic monoterpenes; GLV, green leaf volatiles; HEX, C6 lipid derivatives; OTH, other volatiles; PCoA, principal coordinates analysis; PEA, phenethyl alcohol; RI, retention index; SSQ, sesquiterpenes; TD-GC-MS, thermal desorption-gas chromatography-mass spectrometry; VOC, volatile organic compounds.

14个月季品种挥发性有机物多样性研究

摘要:本研究阐明了利用顶空气相色谱-质谱分析方法对14个现代玫瑰品种的104种挥发物含量进行多元分析的重要性。尽管挥发物含量不同，但“Lady Emma Hamilton”、“Golden Celebration”和“the Poet’s Wife”这三个品种的挥发性有机化合物(VOCs)含量相似，而且不含苯乙醇，而苯乙醇通常与特有的“玫瑰”香味有关。R. ' Hansa '是挥发物最丰富的品种，挥发物含量高，无环单萜烯和芳香化合物含量高。月季‘August Gervais’中未检测到单萜类化合物。研究表明，高香品种产生的挥发性有机化合物强度更高，多样性更大。这些发现也证明了利用顶空分析来比较玫瑰品种的天然香气的潜力，这为激发香水和食品工业的创新提供了信息。缩写AMT，无环单萜;ARM:芳香化合物;CMT，环单萜;GLV:绿叶挥发物;HEX, C6脂质衍生物;OTH，其他挥发物;主坐标分析;PEA，苯乙醇;RI:保留指数;SSQ,倍半萜烯;TD-GC-MS，热解吸-气相色谱-质谱;VOC，挥发性有机化合物。图形抽象

期刊介绍： Journal of Essential Oil Research ( JEOR) is the major forum for the publication of essential oil research and analysis. Each issue includes studies performed on the chemical composition of some of the 20,000 aromatic plants known in the plant kingdom. JEOR is devoted entirely to all phases of research from every corner of the world by the experts in their field. JEOR''s main areas of focus include: -Analytical chemistry- Biological activity- Biotechnology- Chemical composition- Chemical synthesis- Chemosystematics- Microbiological activity- Plant biochemistry/biosynthesis- Toxicology. Published six times per year, JEOR provides articles on the aromatic principles of a plant or its isolates and are directed toward furthering our readers'' knowledge of the aromatic plant and animal kingdoms.
