    Abstract:
    OBJECTIVE: To compare the content of water, ethanol soluble extracts and tetrahydropalmatine in crude and processed Corydalis Rhizoma samples from different habitats. METHODS: Corydalis Rhizoma was processed according to the optimum processing of the Chinese Pharmacopoeia (2010 edition), and then, the difference of the content of water,ethanol soluble extracts and tetrahydropalmatine in crude and processed Corydalis Rhizoma samples were analyzed and compared. RESULTS: From 14 different batches of Corydalis Rhizoma studies, the content of water, ethanol soluble extracts and tetrahydropalmatine in crude Corydalis Rhizoma was 12.8%-14.8%, 16.5%-19.6% and 0.043%-0.075%, respectively; As for Corydalis Rhizoma after processing with vinegar,the content of water, ethanol soluble extracts and tetrahydropalmatine was 7.58%-11.7%, 17.8%-23.5% and 0.046%-0.079%, respectively. CONCLUSION: The content of water, ethanol soluble extracts and tetrahydropalmatine varies slightly in the same type of samples from different habitats,which might be due to the difference in soil and climate in each habitat.
