The fragrance is volatile and is prone to radical reactions by light or heat. In particular, theby-products generated by radical reactions are likely to be harmful to the human body. In addition, overexpression of free radicals is known to cause various pathophysiological disorders such as cardiovascular disease, diabetes, ischemia, anemia reperfusion injury, coronary atherosclerosis, Alzheimer's, cancer, as well as aging. Therefore, accurate harmful component quantitative analysis is necessary for the fragrance.In this study, the results of gas chromatograph-mass spectrometer (GC-MS) and gas chromatographic-vacuum ultraviolet (GC-VUV) analysis were compared. In addition, to reduce the generation of harmful substances in natural and synthetic fragrances, the experiment was conducted to prepare and analyze synthetic fragrances. We synthesized fragrances and developed eco-friendly fragrances through quantitative analysis of harmful ingredients by GC-VUV.As a result of this study, it was confirmed that harmful substances of benzene are detected through GC-MS and GC-VUV in natural fragrance analysis. As a result of the synthetic fragrance analysis, unlike the natural fragrance, no harmful substances of benzenes were detected, but it was confirmed that butyric acid methyl ester, which was not detected by GC-MS, was detected as a by-product in GC-VUV analysis. As a result of controlling the content of ethyl butyrate, the concentration of butyric acid methyl ester decreased as the ratio of ethyl butyrate decreased.In this study, we were able to synthesize natural fragrances with low content of harmful substances. GC-VUV is expected to be useful for analysis of harmful substances in perfumery and cosmetic fields along with GC-MS.
