In this study, an accelerated solvent extraction dispersive liquid-liquid microextraction coupled with gas chromatography and mass spectrometry was established and employed for the extraction, concentration and analysis of essential oil constituents from Ligusticum chuanxiong Hort. Response surface
The volatile oils of 23 Ligusticum chuanxiong Hort. samples from 4 different regions were analyzed by comprehensive two-dimensional gas chromatography/time-of-flight mass spectrometry (GC x GC/TOF MS). The group-type separation of 4 terpenoids and phthalides was well accomplished based on a DB-Petro
