Influence of Processing Technology on Andrographolide and Dehydroandrographolide Contents in Andrographis Tablet / 中药新药与临床药理

ABSTRACT

On the basis of thermal stability of andrographolide and dehydroandrographolide,the influences of medicinal material factors(habitats,collecting time,storage time),thermal stability,production technology(solvent,temperature,heating time and storage condition)on the content of andrographolide and dehydroandrographolide in Andrographis Tablet(AT)were explored so as to increase the quality of AT.The results showed that the excellent medicinal material of Herba Andrographis,optimized production technology,shorter heating time and lower temperature are the effective measures for increasing the quality of AT.
