The constituents of essential oils and organic extracts from peel and kernels of Citrus japonica were analysed by GC and GC/MS. The content of essential oil in peel and kernel was 1.1 and 0.8% based on dry weight. The essential oil of C. japonica peel and kernel was characterised by a higher amount of limonene (51.0 and 47.1%) and germacrene D (12.1 and 6.3%), and the hexane extracts of its peel and kernel were characterised by a higher amount of dodecanol-1(12.9 and 20.8%) and linolenic acid (13.1 and 16.3%), respectively. The antioxidant activities of oils were evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. The results indicate that both oils from different parts of C. japonica possess considerable antioxidant activity. The fruit peel and kernel essential oil could thus be useful in the industries, chiefly in the food and pharmaceutical industries.
采用气相色谱（GC）和气相色谱 - 质谱联用（GC/MS）技术分析了日本柑桔果皮和果仁中精油及有机提取物的成分。基于干重，果皮和果仁中精油的含量分别为1.1%和0.8%。日本柑桔果皮和果仁的精油以较高含量的柠檬烯（分别为51.0%和47.1%）和吉马烯D（分别为12.1%和6.3%）为特征，其果皮和果仁的己烷提取物分别以较高含量的1 - 十二醇（分别为12.9%和20.8%）和亚麻酸（分别为13.1%和16.3%）为特征。通过1,1 - 二苯基 - 2 - 苦基肼（DPPH）法评估了这些油的抗氧化活性。结果表明，来自日本柑桔不同部位的两种油都具有相当的抗氧化活性。因此，该水果的果皮和果仁精油在工业中可能有用，主要是在食品和制药行业。
