Essential Oil of Glycosmis stenocarpa (Drake) Leaves Grown in Hai Duong Province, Vietnam

In this study, the extraction of essential oil of Vietnamese Glycosmis stenocarpa leaves was conducted using two different methods such as conventional microwave-assisted hydrodistillation (MAHD) and hydrodistillation (HD). The obtained products were analyzed by gas chromatography-mass spectrometry (GC-MS). The essential oil quality was attained in a comparable manner in both samples respectively. In addition, the GC-MS analysis showed that the hydrodistillation essential oil contains a total of 29 chemical compounds, whereas the MAHD essential oil contained 28 constituents. Moreover, the chemical constitutes of the two essential oils were similar, with the major components being citronellal, neryl acetate, citronellyl acetate and geranyl acetate.
