Abstract An effective analysis method for tablet of Corydalis tuber for alleviating pain was developed by high performance liquid chromatography in the presence of solvent mixtures of acetic acid, triethylamine, methanol, and water in gradient elution. It was applied to 12 tablet samples that were collected stochastically from pharmacies and hospitals. An image chromatographic fingerprint was developed and four marker compounds were identified in the fingerprint. A digitized chromatographic… CONTINUE READING
