花的气味已经被证明会引起蝴蝶的行为反应，蝴蝶在收到适当的信号后会觅食花朵。相对于花香味的研究而言，叶香味的研究则相对较少。采用空气夹带法采集樟科植物樟叶挥发物，在电生理和行为学测试中，均表现出对日本纹凤蝶（Graphium sarpedon nipponum）的活性。挥发性成分采用毛细管气相色谱-电子探针检测法（GC-EAD）进行分析。经气相色谱-质谱联用（GC-MS）分析，确定了两种具有电生理活性的化合物，分别为壬醛和癸醛。雌蝶对顶空挥发物和具有触角电位活性的醛类的触角电位反应一般比雄蝶大。两个触角电位活性醛被发现在引诱剂测试是有吸引力的两性蝴蝶单独处理时。虽然性别差异不显著，但雌性蝴蝶的偏好往往比雄性更活跃。
Floral scent has been shown to elicit behavioral responses by butterflies which forage for flowers after receiving appropriate signals. In comparison with investigations about the role of floral scent, those of foliar odor are, however, very few. In this study, the foliar volatiles of Cinnamomum camphora (Lauraceae), which had been collected by air entrainment, exhibited activities toward Graphium sarpedon nipponum (Papilionidae) in both electrophysiological and behavioral tests. The volatiles were analyzed by capillary gas chromatography with electro-antennographic detection (GC-EAD). Two electrophysiological active compounds were found which were determined as nonanal and decanal by using gas chromatography-mass spectrometry (GC-MS). Female butterflies generally tend to show a greater EAG response than males to the headspace volatiles and EAG-active aldehydes. Two EAG-active aldehydes were found in attractant tests to be attractive to both sexes of the butterfly when treated individually. Although the difference between the sexes was not significant, the female butterflies' preference tended to be more active than that of the males.
