Laser capture microdissection(LCM) combined with gas chromatography-mass spectrometry(GC-MS) was employed to investigate the distribution of volatile compound in the secretory cavities of different tissues(cortex, phloem, xylem, and pith) in different rhizome sections of wild Atractylodes lancea. The same method was used to study the metabolic characteristics of the volatile compounds in the secretory cavities of different rhizome tissues of A. lancea transplanted for 1-3 years.
