Phytochemical Analysis of Plant Extracts by Using Advanced Gas Chromatography and Mass Spectrometry

Abstract:

Plant metabolite measurements are formidable challenges to plant biologists due to the limited platform sensitivity, or unavailability of a generic analytical method to achieve unbiased simultaneous identification and quantification of plant metabolomes. Recently, Wong has tackled this problem to try to provide better metabolite coverage, by using multidimensional gas chromatography (MDGC) methods. In this talk, Wong will be sharing with us on how he applied high resolution methods to a variety of plant essential oils, such as agarwood oil (Aquilaria malaccensis), tea tree oil (Melaleuca alternifolia), and eucalyptus oil. Clearly, higher dimensionality is required to expand the metabolic coverage of total components identified in plant extracts, and for successful enantiomeric analysis of designated terpenes in plant oil for authenticity assessment.

Speaker's Profile:

Yong Foo Wong is a PhD candidate in the School of Chemistry, Faculty of Science, Monash University. He was awarded a Master of Science degree from the Universiti Sains Malaysia in Oct 2013. His current research interests include development of high-resolution metabolic profiling approaches (MDGC and GC×GC with advanced mass spectrometry) applied to essential oils and plant extracts. He also has an interest in authenticity assessment of essential oils. He is the author of 8 research articles.
