RESUMEN
In this paper, it is found that the preferential growth of secondary {117} facets of Bi24O31Br10 into dominant facets would lead to higher photocatalytic activity, although the original main {213} facet has a stronger molecular oxygen adsorption ability, which illustrates that the charge separation efficiency induced by dominant/secondary facet control plays a more important role than that of O2 adsorptive performance in improving activity.
RESUMEN
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.
