Microwave-Assisted Hydrodistillation of Jasminum Sambac and Its Chemical Constituents


Medicinal and Aromatic Plants Seminar (MAPS 2008)


21st October - 22nd October 2008

Place Held

The Legend Hotel, Kuala Lumpur


Extraction of fresh flowers of Jasminum sambac (closed bud and fully bloomed flowers) were carried out using microwave-assisted hydrodistillation technique (MAHD). The chemical composition of the essential oils obtained were analysed by capillary GC and GC-MS. The main chemical compounds identified from the bud and flower oils, respectively, were (E,E)-α-farnesene (14.36%, 13.10%) and linalool (4.89%, 1.16%). Chemical components usually found in jasmine essential oils such as cis-jasmone, benzyl acetate (0.27%). benzaldehyde (0.20%) and α-gurjunene (0.34%) were detected from the closed buds. On the other hand, only cis-3-hexenyl benzoate (6.63%) and geranyl linalool (7.09%) were found in the flower oil. Other components found in the flower oils were hydrocarbons and made up of 23.91% of the oil. From this study, we found that the bud oil contained some of the aroma compounds contributing to the jasmine odour. Although the fully bloomed flowers gave a more distinctive aroma, it was possible that the volatile compounds coud have evaporated prior to the distillation process. Our study showed that MAHD was suitable for extracting essential oil within a short period (1 h and 40 min) and useful for the rapid identification of essential oil components.
