Abstract
In the present research, the indicator compounds in Gardenia jasminoides Ellis and Arctium lappa L. were purified and used as standards to analyze the crudes and concentrated herbal extracts of local GMP manufacturers with the aid of high-performance liquid chromatography. Themethods validation examinations were performed to confirm that these methods were precise and reliable. Thus they were subjected into the fingerprint chromatogram analyses of G. jasminoides and A. lappa and the results suggested that the chromatographic fingerprints could improve the products quality of the traditional Chinese medicine preparations.
