Analysis of the influence of sulfur-fumigation on the volatile components of Angelicae sinensis Radix by comprehensive two-dimensional gas chromatography/time-of-flight mass spectrometry

Background: Sulfur-fumigation of Angelicae sinensis Radix causes changes in the structure and composition of volatile components. These changes alter the curative effect and the quality of A. sinensis Radix. Materials and Methods: In this study, comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC × GC-TOFMS) was employed to investigate the influence of sulfur-fumigation on the volatile components,...
