橙皮挥发油的提取及成分分析

Extraction and Identification of Volatile Oil in Fresh Orange Peel

采用水蒸气蒸馏法提取橙皮中的挥发油,并用气相色谱-质谱联用仪分析挥发油的组成成分。结果表明,橙皮中挥发油橙香味浓郁,其主要成分为柠檬烯,气相色谱中的保留时间为6.72min,含量达到80%以上。

Conventional hydrodistillation （HD） was used to extract volatile oil in fresh orange peel ,and the chemical components were separated and identified by using Gas chromatography-mass spectrometry （GC-MS） .The results showed that the volatile oil in fresh orange peel was very sweet-scented ,and the main component in the volatile oil is limonene ,whose gas chromatography retention time was 6.72 min ,and content was more than 80% .
