| 摘 要： | [目的]考察蒸馏时间对丁香油化学成分的影响。[方法]采用水蒸气蒸馏法提取不同蒸馏时段的精油馏分，通过气相色谱-质谱（GC-MS）映用分析鉴定其化学成分。[结果]不同蒸馏时段丁香油的主要化学成分为：丁香酚（85．574％～58．519％）、乙酸丁香酚酯（8．845％-30．584％）、β-石竹烯（1．758％-5．680％）、α-石竹烯（0．257％～1．005％）。[结论]蒸馏时间对丁香油的化学成分有较大影响，随着蒸馏时间的延长，丁香酚的含量逐渐降低，而乙酸丁香酚酯的含量逐渐升高。

| Abstract: | [Objective] The aim was to study effects of distillation duration on the chemical composition of essential oil from Eugenia caryophyllata Thunb.[Method] The essential oil fractions collected at different times during distillation were obtained through hydrodistillation and analyzed by gas chromatography-mass spectrometry(GC-MS) method.[Result] The main constituents in oils collected at different times during distillation were eugenol(85.574%-58.519%),eugenol acetate(8.845%-30.584%),β-caryophyllene(1.758%-5.680%) and α-caryophyllene(0.257%-1.005%).[Conclusion] The constituents of oil from E.caryophyllata Thunb varied obviously with the duration of distillation.The relative content of eugenol decreased with the distillation processing,while that of euganol acetate increased. |
