用气相色谱-质谱法(GC-MS)、感官评价法和气味活性值法(OAV)测定了雌雄花蕾挥发油的化学成分，并对其香气活性成分进行了分析。这些油中含有85种化合物。我们首次从刺参中鉴定出44个化合物。通过感官评定，用气相色谱-嗅觉仪(GC-O)鉴定了19种香气活性物质。由于化学成分会影响植物和食草性昆虫之间的相互作用，我们的结果表明，日本野菜雄花和雌花的精油对草食动物的影响不同。精油的性别差异值得在这一植物昆虫系统中进一步研究。
This study was conducted to determine the composition of essential oil from buds of male and female Eurya japonica flowers and to determine the aroma-active compounds of this plant by gas chromatography-mass spectrometry (GC-MS), sensory evaluation, and odor activity values (OAV). The oils contained eighty-five compounds. We identified for the first time forty-four compounds in E. japonica. Through sensory evaluation, nineteen aroma-active compounds were identified by gas chromatographyolfactometry (GC-O). Because the chemical composition can affect the interaction between plants and herbivorous insects, our results suggest that essential oils from male and female flower buds of E. japonica differently affect herbivores. Sexual differences in essential oils deserve further investigations in this plant insect system.
