Chuanxiong or kot-hua-bua samples in Thailand were identified by macroscopic and mi-
croscopic examinations, chemical reactions, thin-layer chromatography (TLC), and ultraviolet
(UV) spectrum and compared with the samples from the People’s Republic of China. It was
found that the characteristics of both types of samples were not different. However, the crude
drugs could be classified into two groups based on their macroscopic characters: one was dried
herb having a fist-like shape and the other was sliced and stirred in yellow wine to be a brownish
red slice. The chemical compositions of these two groups were different and clearly detected by
TLC.

Key words: Chuanxiong, Kot-hua-bua, quality, Chinese crude drugs.
