Chemical Composition of the Essential Oils from Flowers and Leaves of Marsdenia erecta Using Microwave Assisted Hydrodistillation Technique

摘要

In this study, microwave assisted hydrodistillation (MAHD) technique was successfully used to separate volatile essential oils from flowers and leaves of Marsdenia erecta. The obtained oils were subsequently analyzed using the gas chromatography combined with the mass spectrometry (GC-MS) technique. A total of 19 and 15 compounds were identified in the profiles of flowers and leaves, constituting 93.5 % and 90.6 % of the chemical profiles, respectively. Our study revealed the presence of high quantities of linalool in the extracted oils. Additionally, in both oils, oxygenated monoterpenes were the most abundant natural compounds, while the second and third ranks were due to non-terpene hydrocarbons and oxygenated diterpenes, respectively.
