Advances of Modern Gas Chromatography and Hyphenated Techniques for Analysis of Plant Extracts

Abstract

Modern gas chromatography, with the development of advanced analytical techniques, has become a fundamental tool for the separation and characterization of plant extracts. These last issues are absolutely important if considering the widespread use of plant derivatives not only in pharmaceutical/food industry but also, for a large part, in traditional and alternative medicine, which require a high level of quality and safety. Hence, the development of new, powerful hyphenated GC techniques were reviewed in this article, including Gas Chromatography-Mass Spectrometry (GC-MS), Solid Phase Microextraction-Gas Chromatography (SPME-GC), Gas Chromatography-Fourier-transformed Infrared Spectroscopy (GC-FTIR), Multidimensional Gas Chromatography (MDGC) and Comprehensive Gas Chromatography (GCxGC). Several applications of each technique were reported and illustrated.

“…Comprehensive twodimensional gas chromatography, characterized by powerful and increased separation capability, has been introduced and successfully applied to the field of life sciences (Costa, Dugo, Santi, Dugo, & Mondello, 2010;Tranchida, Dugo, Dugo, & Mondello, 2004). Considered a new promising branch of separation science, multidimensional gas chromatography, characterized by the combination of different types of stationary phases, has proved to be a powerful and effective tool for flavor and fragrance analysis.…”
