The objective of the present study was to characterize chemically the essential oils of two distinct propolis types: Brazilian red and Taiwanese green. Unlike the non-volatile chemical composition of these types of propolis, which has been extensively studied, the knowledge of the essential oils is scarce or even not investigated. The essential oils were obtained by hydrodistillation of raw propolis samples using a Likens-Nickerson type apparatus and then analyzed by GC/MS. The main volatile components of Brazilian red propolis were the phenylpropanoids: elemicin (26.1-27.5%), methyl eugenol (16.3-23.8%), trans- methyl isoeugenol (9.2-11.6%), isoelemicin (6.1-7.1%) and trans-anethole (4.4-7.1%), while the major constituents of Taiwanese green propolis essential oil were: β-eudesmol (13.9%), 6-methyl-3,5-heptadiene-2-one (12.2%), y-eudesmol (4.4%), geranial (4.1%) and 6-methyl-5-heptene-2-one (3.7%).
本研究的目的是对两种不同类型蜂胶（巴西红蜂胶和台湾绿蜂胶）的精油进行化学特征分析。与这些类型蜂胶的非挥发性化学成分已得到广泛研究不同，关于其精油的知识却很匮乏，甚至尚未被研究。通过使用Likens-Nickerson型仪器对生蜂胶样品进行水蒸馏来获得精油，然后用气相色谱/质谱联用仪（GC/MS）进行分析。巴西红蜂胶的主要挥发性成分是苯丙素类化合物：榄香素（26.1 - 27.5%）、甲基丁香酚（16.3 - 23.8%）、反式甲基异丁香酚（9.2 - 11.6%）、异榄香素（6.1 - 7.1%）和反式茴香脑（4.4 - 7.1%），而台湾绿蜂胶精油的主要成分是：β-桉叶醇（13.9%）、6-甲基-3,5-庚二烯-2-酮（12.2%）、γ-桉叶醇（4.4%）、香叶醛（4.1%）和6-甲基-5-庚烯-2-酮（3.7%）。
