【摘要】 以大马士革玫瑰精油为研究对象,利用GC-MS和GC-O/AEDA法结合香气重组试验鉴定玫瑰精油样品的特征香气化合物。结果显示,玫瑰精油的特征香气化合物主要为萜烯类、醛类、醇类、酮类、酚类、酯类、酸类以及少量的醚类化合物。通过香气重组试验以及感官分析结果得出影响玫瑰精油香气的主要感官属性为青香、木香、脂香、甜香、辛香、花香、果香。对比GC-O稀释法与感观分析结果表明37种特征香气化合物对玫瑰精油整体香气的贡献作用。更多还原

【Abstract】 In this study, the volatile aroma compounds in 2 rose oils were studied using GC/MS and GC-O(AEDA) method combined with reconstruction experiment to identify the characteristic aroma compounds of rose essential oil samples from different area. The result showed that the characteristic aroma compounds of rose essential oil, mainly terpene class, aldehydes, alcohols, ketones, phenols, and a small amount of ether compounds. The main sensory attributes of rose oil are green, woody, fatty, sweet, spicy, floral and fruity identified by GC-O/AEDA and sensory attributes.Comparison of GC-O/AEDA and sensory analysis further explain the contribution of characteristic aroma to the overall aroma rose essential oil.更多还原
