Abstract The rich and diversified Malaysian flora represents an excellent resource of new chemical structures with biological activities. The genus Xylopia L. includes aromatic plants that have both nutritional and medicinal uses. This study aims to contribute with information about the volatile components of three Xylopia species essential oils: Xylopia frutescens, Xylopia ferruginea, and Xylopia magna. In this study, essential oils were extracted from the leaves by a hydrodistillation process. The identification of the essential oil components was performed by gas chromatography (GC-FID) and gas chromatography–coupled mass spectrometry (GC-MS). The major components of the essential oils from X. frutescens were bicyclogermacrene (22.8%), germacrene D (14.2%), elemol (12.8%), and guaiol (12.8%), whereas components of the essential oils from X. magna were germacrene D (35.9%), bicyclogermacrene (22.8%), and spathulenol (11.1%). The X. ferruginea oil was dominated by bicyclogermacrene (23.6%), elemol (13.7%), guaiol (13.4%), and germacrene D (12.3%).

三种马来西亚木兰属植物（番荔枝科）的精油成分

摘要 马来西亚丰富多样的植物群是具有生物活性的新化学结构的极好资源。Xylopia L. 属包括具有营养和药用用途的芳香植物。本研究旨在提供有关三种木皮属植物精油的挥发性成分的信息：Xylopia frutescens、Xylopia ferruginea 和 Xylopia magna。在这项研究中，精油是通过水蒸馏过程从叶子中提取的。精油成分的鉴定通过气相色谱法 (GC-FID) 和气相色谱-耦合质谱法 (GC-MS) 进行。X. frutescens 精油的主要成分是双环锗烯 (22.8%)、锗烯 D (14.2%)、elemol (12.8%) 和愈创木酚 (12.8%)，而 X. magna 是锗烯 D (35.9%)、双环锗烯 (22.8%) 和匙羹藤醇 (11.1%)。X. ferruginea 油以双环锗烯 (23.6%)、elemol (13.7%)、愈创木酚 (13.4%) 和锗烯 D (12.3%) 为主。
