GC-MS Analysis of Volatile Components in Shanghai Yulania denudate Floral Fragrance and Fresh Flower Essential Oil
To assess the differences in composition between the fragrance of Shanghai Yulania denudate fresh flowers and the essential oil extracted from fresh Y.denudate flowers,volatile constituents were analyzed by using headspace gas chromatography-mass spectrometry(HS-GC-MS)or gas chromatography-mass spectrometry(GC-MS).The results revealed a total of 44 identified compounds from both fragrance and essential oil,with 10 compounds common to both.The fragrance exhibited 26 components,accounting for 96.29％of the total,characterized predominantly by eucalyptol(26.73％),sabinen(23.29％),β-pinene(18.77％),β-myrcene(12.22％)and α-pinene(6.83％).The fresh flower essential oil contained 28 chemical constituents,comprising 79.46％of the total,with major components including phenylethanol(35.48％),eucalyptol(10.09％),α-terpineol(9.12％),cryptomeridiol(5.69％)and 4-terpineol(5.52％).Differences in the composition and relative proportions of components between the fragrance and essential oil of Y.denudate provide a scientific basis for the rational exploitation of this resource.
