摘  要：
[目的]分析比较不同方法提取柑橘皮中挥发性成分的效果。[方法]分别采用水蒸气蒸馏(SD)和超声萃取-水蒸气蒸馏(UESD)从柑橘皮中提取挥发油,通过气相色谱-质谱(GC-MS)联用技术,比较分析了挥发油的化学成分;峰面积归一化法确定了各组分的相对百分含量。[结果]SD法共分离出30个色谱峰,鉴定出21种物质,占总峰面积的93.89%,主要是邻苯二甲酸(51.93%);UESD法共分离出45个色谱峰,鉴定出38种物质,占总峰面积的98.07%,主要是D-苎烯(25.90%)等。[结论]2种方法提取柑橘皮中挥发油主要共有成分为有机酸和烷烃类化合物,但组成和含量有差异,SD法提取有机酸的含量较高。

摘  要：
[Objective] To compare different extraction method for volatile oil from orange peel.[Method] The volatile oils were extracted from orange peel by steam distillation(SD) and ultrasound-assisted steam distillation(UESD),respectively.The chemical constituents in the volatile oils were identified by Gas Chromatography-Mass Spectrometry GC-MS and their relative contents were calculated based on GC peak areas.[Result] For steam distillation,21 compounds of 30 detected peaks were identified,accounting for 93.89% of the volatile fraction.The main components were dimethyl phthalate(51.93%);For ultrasound-assisted steam distillation,38 compounds of 45 detected peaks were identified,accounting for 98.07% of the volatile fraction.The main components were D-Limonene.[Conclusion] The results indicated that,there is a significant difference in the composition and relative amounts between the volatile oils obtained by SD and UESD methods;the common components of the two extracts were organic acids and alkanes.SD method allows higher amount of organic acids than UESD.
