Abstract
Mikania micrantha Kunth is widely known as potential herbal medicine, although it is an invasive alien species in Southeast Asia. In this study, the essential oils from leaves and stems of M. micrantha were extracted by hydrodistillation method, and the chemical profiles of essential oils were then analysed by gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC/MS). It was found that there were similarities and differences in chemical compositions and their percentage between the essential oils obtained from these two parts. The dominant components of leaves essential oil are β-Cubebene, Germacrene D, and α-Zingiberene, accounting for 11.34%, 10.96%, and 10.76%, respectively. Additionally, the major components of stems essential oils are D-Limonene (16.99%), β-Pinene (7.91%), and α-Zingiberene (7.26%). The research sheds fresh light on the chemical makeup of M. micrantha essential oils, emphasising their potential for the future.
