Objective:To study on difference of properties of cross-linked povidone(PVPP) and its application in the traditional Chinese medicine.Method: Four kinds of domestic PVPP and three kinds of imported PVPP were chosen
and to study on particle morphology
mobility
swelling capacity
water absorption rate constant and specific surface area
etc;Performance of different PVPP was investigated with Chuangxinlian tablet
Shiquan Dabu tablet
Liuwei Dihuang tablet as model medicine.Result: There were some differences in powder properties and functional parameters of different PVPP
especially it was used in model medicine as disintegrating agent
imported PVPP was better than domestic PVPP on disintegrating performance.Conclusion: Performance of domestic PVPP need to be optimized.
