Abstract
Most perfumes are blend of fragrant organic compounds, which may be natural or synthetic. A wide variety of natural fragrant organic compounds are extracted from flowers by steam distillation or by solvent extraction. These extracted organic compounds are blended in different proportions blending synthetic compounds, whose structures may or may not be similar to the compounds give a signature smell of a floral perfume. Perfumes are also formulated by compounds extracted from the flowers. Jasmine essential oil is widely used in large number of formulations of fragrance products including Channel No 5 perfume. In this study, commercial synthetic jasmine oil was analyzed by gas chromatography – mass spectrometry (GC-MS) on Agilent 7890B GC and Agilent-5977 MS using HP-5 MS 5% Phenylmethyl SILOX 30 m x 250 m x 0.25 m capillary column. The oil consisted of twelve components, which were successfully separated by GC, and were identified by comparison of their mass spectra with a MS database from National Institute of Standards and Technology (NIST). The identified compounds were various esters including methyl jasmonate, ethers, phenolic compounds, and aromatic compounds, such as indole. The research is being further done to identify these compounds by comparison of their retention times with the authentic standards and by nuclear magnetic resonance (NMR).
