OBJECTIVE: To extract volatile constituents from the dried tubers of Xiao Baiqi (A) and Hua Xia Qi (B) of white clay stub columns, and qualitatively and quantitatively analyze them. Methods: Qualitative analysis was performed by gas chromatography-mass spectrometry, and the relative content of each component was determined by gas chromatography. Results: Forty compounds were identified from A and 47 compounds were identified from B. The identification rates were 74.85 % and 81.26 %, respectively. The main component was hexadecanoic acid. Conclusion: The volatile constituents of A, B of two kinds of herbs are almost the same and their contents are slightly different.
