The essential oils and extracts of Mylia taylorii and M. nuda were investigated by gas chromatography, mass spectrometry, NMR spectroscopy and chemical correlations. Beside several known compounds 13 new constituents including three new carbon skeletons could be identified. Four hydrocarbons with a molecular formula of C15H22 (m/z 202) were identified as myli-4(15)-ene (1), aromadendra-1(10),4(15)-diene
通过气相色谱、质谱、核磁共振光谱和化学相关性研究了 Mylia taylorii 和 M. nuda 的精油和提取物。除了几种已知的化合物外,还可以确定 13 种新成分,包括三种新的碳骨架。四种分子式为 C15H22 (m/z 202) 的烃被鉴定为 myli-4(15)-ene (1)、aromadendra-1(10),4(15)-diene (19)、aromadendra-4、 10(14)-二烯 (20) 和芳香树花-4,9-二烯 (21)。三种 oxaspiro 化合物被鉴定为 7-epi-bourbon-3-en-5,11-oxide (22)、guai-3,10(14)-dien-5,11-oxide (23) 和 guai-3, 9-dien-5,11-氧化物 (24)。myli-4(15)-en-3-one (5) 的绝对构型可以通过化学相关性建立。连同 alpha-taylorione
