Abstract
Comprehensive two-dimensional gas chromatography (GC×GC) is an important technique used to investigate complex mixtures with pharmaceutical potential. GC×GC expands the peak capacity of the separation, which increases the resolution for more targeted characterization of analytes of interest and trace chemicals. Traditional gas chromatography–mass spectrometry is used to investigate extracts; however, when the mixture is complex, there is a need for higher resolution power to identify the extracts profile completely and discover new extracts of interest. In this study, inkberry chemical compounds were characterized using GC×GC. Inkberry was chosen because of the lack of literature on its chemical components. Two solvent solutions were used to isolate chemicals from inkberry leaves, acetone and hexane. From the acetone extracts, 2,986 chemicals were identified and 1,653 of them were unknowns. From the hexane extracts, 1,726 chemicals were identified and 698 were unknowns. NIST and Wiley libraries were used for identification.
