摘 要 ：采用水蒸气蒸馏法提取早熟金柚果皮挥发油，通过正交实验优选获得早熟金柚果皮挥发油提取的工艺参数，结果表明：早熟金柚果皮挥发油的最佳提取工艺是将柚皮粉碎60 s，加水5倍，提取6 h。采用GC-MS联用技术对早熟金柚果皮挥发油的化学成分进行分离鉴定，共分离出44个峰，鉴定出了其中的25种化合物，占峰面积的98.43%。用面积归一化法测定了各个组分的相对百分含量，其主要成分有柠檬烯（65.82%）、β-月桂烯（25.52%）、4-侧柏烯（1.78%）、紫苏烯（0.44%）、氧化芳樟醇（0.42%）。

Abstract:The volatile oil of early maturity gold pomelo peel was extracted by watersteaming method. The extraction process was optimized by orthogonal design. The optimum extracting condition obtained: adding 5 folds of water, extracting for 6 hours after smashing 60s. The chemical components were first analyzed by means of GC-MS. Twenty-five components, 98.43% of total content, had been identified from forty-four separated peaks. The main components were Limonene(65.82%), β-Myrcene(25.52%), 4-Thujene(1.78%), Perillene(0.44%), Linalool oxide(0.42%).
