Abstract:
Experiments on the use of ultrafiltration in the preparation of Shengmaiying oral liquid were carried out in comparison with the conventional preparation procedure. Results showed that the product obtained had abetter clarity and less impurities. It is postulated that such technique can be used in the purification of many oral liquid preparations of compounded herbal formulations with efficient removal of impurities while retaining the main active principles. The selection of ultrafiltration equipment,its optimum working pressure,temperature and filtration rate were discussed.
