A qualitative analysis of Litsea fulva essential oils using comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry
A qualitative analysis of the individual compounds in Litsea fulva (locally known as ‘Medang’) essential oils was performed by comprehensive two-dimensional gas chromatography (GC × GC) coupled with time-of-flight mass spectrometer (TOF/MS) for the identification of the resolved peaks. Litsea fulva...
